Hi, I'm not sure whether has this topic been posted here before. I have been hearing stories about how bad RON 95 is. People been telling me that this petrol will easily caused car catch fire. This is why now days we have been seeing and hearing allot of car caught fire. I realized that allot of car caught fire victims ever since RON95 been introduced.

I even hear stories like our Ron 95 is not a real 95. It was from the ron92 that added addictive to produce like Ron 95 which can harm the car engines and parts.

I was using RON95 for my Honda city for about 6 months and my car slowly develops problems. Problems like throttle body and throttle sensor making my car chocking. Car behaving weird and when sent to HONDA, the machenIC told me not to use ron95 as it will wear out car parts and damage easily. I experienced difficulties of gear shift. Feels like it dO not want to shift to the next gear, lagging or something. The engine raw. It's louder than before and felt lack of power. So when mechanic advice to use rOn97. Everything works find now. Gear shifting is smooth and no more weird behavior like car chockIng engine dying. Engine is quieter like before.

I would like to hear what are your opinions

RON 81, RON 85, RON 90, RON 95, RON98, RON 101, any petrol no matter what octane number/rating will also easily catch fire one lah doh.gif

Try take a ceramic cup and pour some petrol in it. Light up a match stick and just carefully wave the match stick across the surface. It will ignite even the matchstick didn't comes into contact to to the petrol surface. It was due to petrol vapor and petrol can easily vaporize the moment it come into contact with air, especially hot weather.

My neighbour's using a Honda City too, and he has been pumping RON95, and his car has no problem at all. Seldom heard him complaining about his car and certainly never heard him telling me those problems you are facing back then when you are still using RON95.

BTW, Honda mechanic are full of shits. They can cook up a lot of stories so that they can deny customer's warranty claim. I have a friend who drove a Honda Civic. He experience jerking and sometimes cant accelerate smoothly. The mechanic at a few Honda SC keep on reset his ECU for 8 times. They keep on insist that the gearbox has no problem, saying that "1 year old gearbox from Honda wont have problem one" and therefore it doesn't need checking. I go over and F them and when they decide to run a diagnostic check on the gearbox, they found out something in there is wonky. Wont have problem my foot.

Stories designed for folk out there that will believe everything people tell them. I'm using RON-95 and my car doesn't give any problems. Have poured from different retailers also no issues. For more modern cars with ECU, the engine management system will detect your fuel and adjust the engine characteristics accordingly. Of course RON 97 will give more power and smoothness, that is already proven / given with the available research out there.

It happens to my kelisa as well before I Sold it. Symptoms like engine raw and lack of power. Gear box reluctant to shift gear( auto). Engine vibrate violently. After switching back to 97. Everything ok.

This mechanic probably have not studied science before? RON 95 vs 97 is just a difference in octane level and modern cars have knocking sensors that will automatically switch maps according to RON levels. However I do agree than RON 97 will make the car feels better in terms of performance but it is not true that RON 95 will kill your engine because if it does, 90% of the cars in Malaysia will be damaged by now biggrin.gif

Actually newer ones don't need as the knock sensor will automatically adjust to the petrol octane
Old cars like mine with a Proton 1.6 engine, have to play with distributor if you are using stock ECU parameters, or get a programmable ECU for tuning

fuel inconsistent quality had caused issues on my friend's car too. she mainly uses 95. need to drain out the whole batch and refill with fresh ron95 then only solved problem of jerking.

Most proton and perodua cars can use R95. Imported cars, some need R97 due to engine knock issue. Check with your car manual, its all written there.

I'm running DOHC 1.6
Using RON95 my car got knocking issue, adjusted the distributor can reduce just a little bit, engine slightly less power as my engine is high compression and need higher RON bcos it is harder to combust laugh.gif

But so far is still ok la, since it is cheap, I pumped 97, tak boleh tahan wei~~~

how come ron95 use affect gearbox performance?

just nowadays too many car burnt issue MIGHT BE due to nowadays too many car accessories shop open and all act like pro installer tap wire here and there...today's car wiring system sometime is very sensitive if u tap the wire, its either the wire will get hot and caused flicker and the flicker caught up with the petrol fume thus trigger the fire burning the whole car...

it's the knocking problem that caused problems...

95 caused more knocking % than 97 and it can cause serious damage to your piston and block...

however this is depends on luck, some driver no prob at all but some did...

herm, this is the catch, i dunno what is honda's mechanic problems, but honda city runs in thailand n indonesia using ron 91 n ron 88. N in singapore also can run on ron 92@95. Even if malaysia is ron 92 with additive to make it ron 95(i dont think so), but it still higher than ron 91 n even higher than ron 88. I wonder why suddenly honda city in malaysia need ron 97?

New modern cars can retard its timing to coupe with the lower octane. I think its the ecu problems. Whether they dont want to claim it or any other reason. Loss of performance yes, but causing problems to engine, nope i think unless the ems has prob. Unless its equip with super high compression ratio performance engine like type r engine, but dont think so.

I think better ts go to other reputable honda service centre to check the probs. Maybe some forumers can help.

simple to think is like this

less knock = timing more advance = more power
more knock = timing retard = less power

octane is basically how well the fuel resist knocking.

higher the grade the more resistive it is.

just my 2 cents

Technically speaking, octane grade is how much the fuel can be compressed before detonating without a spark, which causes knocking. The higher the grade, the more it can be compressed before combusting without spark.

This is why the 1.6 Campro CFE engine has less compression ratio than the normal 1.6 Campro, to accomodate lower RON petrol in other countries.

Technically speaking, octane grade is how much the fuel can be compressed before detonating without a spark, which causes knocking. The higher the grade, the more it can be compressed before combusting without spark.

This is why the 1.6 Campro CFE engine has less compression ratio than the normal 1.6 Campro, to accomodate lower RON petrol in other countries.

yes.. i lazy type so long ma tongue.gif

actually abt the cfe is not really accurate. turbo car has less compression ratio coz you pack more air in the same amount of space. so you cant compress it too much without it giving you other issues...

no problem. still working after 6 years. of course in terms of performance ron95 a bit inferior compared to ron97. but definitely using ron95 wont harm my p2 engine.

No problems with my Conti. Not even with the super aggressive E10 (10% ethanol) when driving in Europe. Actually E10 even fixed my car, the fuel gauge is working again. thumbup.gif

But really, a good car that was designed for RON 95 shouldn't have any problems. Maybe Japanese cars aren't so good and require higher quality fuel? With the difference in fuel price who would want to use RON 97 if they can get along with 95? Except for petrol station owners perhaps who want you to buy the more expensive fuel. hmm.gif

yep..turbo already have high pressure. so the compression ratio must be lower compared to na engine. thats why if want to bot na engine..need to use low compression piston(if the boost is high). smile.gif

The compression ratio was set at 8.9:1, which although relatively low for a modern downsized engine, allows the same hardware to be used for all the target markets including those with 88 RON fuel and very hot climates without excessive retardation.


But you are perhaps correct as the fact that it is a turbocharged engine was probably also taken into consideration.

And how the heck does fuel damage the throttle body? How can the fuel damage any parts that it does not come into direct contact? Might as well say that by just driving the car on the road the paint is being worn off by using RON95 petrol. rclxub.gif rclxub.gif rclxub.gif rclxub.gif rclxub.gif rclxub.gif rclxub.gif rclxub.gif

-When you last changed your spark plugs

Hi, I'm not sure whether has this topic been posted here before. I have been hearing stories about how bad RON 95 is. People been telling me that this petrol will easily caused car catch fire. This is why now days we have been seeing and hearing allot of car caught fire. I realized that allot of car caught fire victims ever since RON95 been introduced.

I even hear stories like our Ron 95 is not a real 95. It was from the ron92 that added addictive to produce like Ron 95 which can harm the car engines and parts.

I was using RON95 for my Honda city for about 6 months and my car slowly develops problems. Problems like throttle body and throttle sensor making my car chocking.  Car behaving weird and when sent to HONDA, the machenIC told me not to use ron95 as it will wear out car parts and damage easily. I experienced difficulties of gear shift. Feels like it dO not want to shift to the next gear, lagging or something. The engine raw. It's louder than before and felt lack of power. So when mechanic advice to use rOn97. Everything works find now. Gear shifting is smooth and no more weird behavior like car chockIng engine dying. Engine is quieter like before.

I would like to hear what are your opinions

TS,
Strongly suggest u bring ur ride to another SC or mechanic. No way can lower octane petrol can cause damage to d parts u mentioned. Wats ur milleage? For ur sensor, hv it cleaned (theres a DIY method of cleaning it if its not mechanically faulty) or replaced while hv ur throttle body checked/cleaned coz any of these 2 can cause unwanted jerkiness reponse.

As for ppl who complain bout very poor fc n performance after downgrading from higher octane fuel, suggest tat u drive 2 or 3 tanks wit d lower octane fuel 1st. Normally d settings n fuel line would b completely b 'flushed' by then. I personally also noticed different brands having different effeciency effects on cars. So u might wanna maintain d same fuel brand for a couple of tanks as u hunt for ur 'suitable' fuel.

N by d way, also noticed many ol time mechanics, sales or basically performance driven ppl would recommend high octane fuel no matter wat car's in topic even though they work just a hair slower with Ron95 or lower.

I hav nvr encounter any prob with RON95 fuel...Shell's sucks for both of my car, my SGTI and e46 318i...Esso and Petronas r okay n good engine sound especially for my 4g93 engine...

Other countries also use RON95, RON92 and RON88 la, no complaints also...i dun think engine catching fire is the fault of fuel, as i know a lot of ppl who nvr check their water level, engine oil level etc...i am a car noob, correct me if i m wrong

depends on each engine. the manual will state what fuel you can use.

e.g. 130Y states RON95. this is carb car, so use RON97 will give no difference since it cannot change the timing automatically
new C200k says RON91-98. this modern car has knock sensors and complete control over valve and ignition timing so it can adjust accordingly.
i heard JDM cars must take RON98

no such thing cause damage if use RON95. good car with good engine can support up to RON92. in thailand their normal grade of fuel is RON92. premium 1 is RON 95. so msian shd not complaning much. only blame the car engine if you car cannot support RON95/92.

IMHO, from $$$ pov, it makes no sense to pump 95 cuz its much more expensive. look at the small piece of paper when you pump petrol, RM3.5x per litre without subsidy. so my question is why would you subsidize a more expensive fuel? why not just give the same subsidy to 97 and this problem wont arise? (RM2.90 gov set market price -RM1.05 subsidy= RM1.85/litre of RON 97)


I am just stating from official figures. I am ignoring performance in this senario.

TRUE..!!
TS, I've experienced in 2 of my cars: kembara & kancil (L5 efrl turbo).
In my kembara's case:
using RON 95 (any brand), when driving @ constant speed of 90kmh and above for more then 5 minutes, engine suddenly choke and flooring the pedal make it worse that the engine will die while moving..even turning the key to start also wont help and i have to free the gear and slowly move to the side of the road and wait for around few minutes before i can start the car again.. at first i tot this is surely engine problem but once during a long journey, i tried filling in ron97 fuel full tank and the problem nvr occur. i tried again filling ron95 when tank almost empty and as expected, the car choke again..so now, i only use ron97 fuel and that surely trims my pocket even more.. only occasionaly i fill in ron95 (when pocket almost empty).. biggrin.gif

My kancil's case:
using ron95 (any brand), when accelarating, the engine shudder/jerks causing a non smooth acceleration.. but no engine die problem as my kembara does. using ron97, no problem occurs.

My hyundai (getz):
no problem using ron95.. just abit sluggish that's all.. as expected.

so, for those having similar problems as i am (engine jerks n die), try using ron97 for a change.. that might solve the problem.. smile.gif

Use RON95 for my Inspira 2.0 for 1 year. No problem.
Savvy RON 95 maybe 2 years...no problem.
Old Myvi 1.3 also 2 years..no problem.

Mostly Petronas (80%), BP(10%), Yang Lain-Lain (10%).

Confirmed it's your car problem. tongue.gif

proton wira. ok bro here the explanation.
most wira on the road now are still run carb. car with carb need to adjust the air/fuel mixture(smooth idle rpm) n' distributor for ignition timing for spark plugs.
b4 RON 95 around our market. most car were tuned with RON 97 spec/running state. tuning not just dyno the car like u read hypertune mag.. every carb engine need to do tuning in order to get running at optimum state(less FC for most normal driver want)

when RON 95 came out. again most of the proton wira(except fuel injection model) car driver/owner don't aware of their car need to go for re-tune. some of carb wira owner run on RON 95 with no problem b'cos either the engine knocking is so small even driver can't feel it. only feel the car was lazy to get going. when used it for years with no problem.suddenly the car act weird. then only seek for mechanic to check. most mechanic claimed is the fuel that cause the problem. actually is not true. why?
mechanical parts ie. carburetor will face wear-and-tear for period of time. even u don't race the engine, it will still worn off the fuel metering parts inside it. depends on condition, either some adjustment or repair can be fixed or parts replace is needed to fix it.

whereas, EFI or MPFI and direction injection engine are run with the help of ECU(Engine Control Unit). a computer box to control the engine during running. most modern car use it with build-in anti knocking sensor to ensure the engine run in smooth and optimum state set by the each car manufacturer. ie. maybe the ECU will retard the engine timing(ignition timing) to suite RON 95. when engine timing been retard of cos the car will feel less power. maybe engine equip with double vanos, vtec,i-vtec, cvtc, vvti,vvel, etc etc..... these system will slightly compensate the power loss from lower RON fuel but will not as responsive/same state like using RON 97 for sure.

JDM car needed RON98 to run on its optimum performance but can run RON95 if needed. I'm driving a swift sport but once awhile I feed it with RON95 no problem also, there's decreased in performance yes but engine kong I said its bullshit.

RON95 have no issue laaa Proton Saga (Old)/Iswara and Wira (Carb) is tune for RON91 (Due to thailand requirement) if not how on hell you drive your car to Thailand cross border over there there is no such thing as RON97 and they pump RON91!!!

all car authorized manufacturer seller (ASEAN country) is compatible with RON91 (minumum requirement)

All recond car (From other country AP car)
-Europe country (RON92 minimum) - supermarket grade, except sport car
- Japan orgin (JDM cars) - (RON95/97 minimum) as Japan lowest RON is RON97 and their premium fuel is RON99 (If car has knock sensor RON95) expect horse power reduction
- US orgin car (RON 95) minimum

RON97 only car

Modified car like Kancil Turbo (Transplant from L2000/L5 etc etc) RON97 min as Car in Japan is RON97

Honda Civic Type-R : RON97 minimum *Recomend by japan RON98/99
so Shell V-power works here

Performance/sport car better RON97 since you guys can afford it smile.gif

Those who transplant engine (half cut from Japan) prefer RON97

Yeah.... RON95 is so corrosive that RON97 is not harlow.;. it is petrol what U ESPECT....

RON95 amd 97 is basically same petrol the different in RON numbers is the ability to combust... 95 combust earlier and 97 later (which add to 97 stability) it is called pre-mature combustion nothing to do with the nature of corrosive or heat...

for HEAT issue check your water level guess something leak... (not your petrol)

Basically, RON95/97 doesn't matter..
What matters is what your stock car is designed to use..

If it's built to use RON95, then it will run well on RON95
Most of our Malaysian cars is built to use both RON95 & 97

The only time RON95/97 makes a difference is when you modify your car engine (for eg. TurboCharge or SuperCharge)

It FELT hotter. 'Feeling' the temperature of 'the engine bay' is not a reliable way of telling if the engine is having problems. Maybe it was more humid at the time you felt that it was hotter? Maybe you just had your air-con working harder? Maybe it's your cooling system? If the temp needle doesn't go beyond the safe level, whatever increase in temperature you feel from the engine bay is most of the time irrelevant. If it does indeed get hot, I wouldn't blame the fuel either. It's not like you're running the car with a mixture of nitrous oxide and methanol. laugh.gif

Relax. If you are not driving high performance cars like that, RON95 is OK for your Proton and low performance Honda City.

Many may not understand what is "placebo effect". To put it layman's term, it's a feeling one will get after paying for some modification, bought a device, filled higher grade petrol, added addictive etc (& also partly because of the "extraordinary" claims in advertisements, sales talk, forum chat etc), to the point that one CANNOT believe what you paid for does not work as claimed even though there may not be noticeable difference in terms of performance from stock or standard settings/tuning. Phew...there...understand now? No? How about this...

Ah Beng found a performance chip in ebay which claims that after installing it, his car horsepower could increase by 30 ponies. A bargain Ah Beng thought at USD60 so Ah Beng bought and installed it. Wow, he said. The car feels smoother, more pickup, and definitely more power!! Ah Beng is happy. Weeks later, Ah Beng after much persuasion from his car kaki, did a dyno & found out his car actually has less horsepower than his friend's who did no modification or added anything at all! His friend drives the same car as Ah Beng. Ah Beng later recovered from his placebo effect.

dont use ron95 for modern car .. our ron 95 is same with 92+addictive .. it was the gov who ask the fuel maker to come up with a low price fuel but better then ron92 .. old car carburator is ok to use ron92-95 -97 new car with fuel injection no no no.. did u notice they is a lot more car with their bonnet paint tearing off due to heat problem??
most car who have been using the ron95 since coming out from the supplier their car started to develop problem now .. first u will notice ur air cond not that cold anymore and ur car engine start to consume more engine oil and leaking oil...check out with ur trusted mechanic ask them since the intro of ron95 did he notice lot more car coming to have a top overhaul due to oil leaking?

yeah....it will run fine on low RON if normal drive
but if want high speed drive, better use higher RON fuel cuz it push the HP to the limit
but truthfully la...our RON95 really is problematic..no offense...especially the shell one tongue.gif
esso/mobil one still the best
now that RON97 reduced to RM2.6...these few weeks i pump half 95 half 97(same amt of RM), the FC is the same as full 95(despite having lower Litre)...and dam, that power feels good, and the engine is so quite and smooth
i always wonder why 97 and 95 difference is so big

Dont wanna believe me is ok. I have driven my waja cps almost 50k km with RON95 without single issue. No knocking whatsoever. Infact I am heavy footer, frequently high speeding and do hill runs sometimes. Should give some effect to my engine if RON95 here really that bad as what u believed.

then now u started to realise that our ron95 did have some problem right .. the difference of octane is so little but the price is 40% difference .

I do agree with you. Of late my SR4 Civic (1.6l ME-216 EFi no-VTEC) since pumping 97 the FC seems to drop a bit also engine noise definitely reduced especially when accelerating. I'm not sure what exactly the difference is but just my theory that in older engines that are no longer as efficient the more combustible RON 97 helps restore some of that lost efficiency thus reducing noise and improving acceleration.

its not problems la...its more like annoyances...louder grumpier engine sound and no power and FC not as good as RON97
there isn't any problem with it, its just annoyance only
it won't cause any damage...its still oil afterall...unless u pour in water thn thats a different story

my car already 220k. been pouring ron 95 ever since it was launched. no oil leak, no problems with the engine. only thing is that fc is slightly higher when compared to pouring 97. yes i drive a 'dumb' proton , im a heavy footer, and i still get 300km for 50 bucks.

theres no issue mixing fuel brand..its the same fuel afterall..only different addictives
if u run out of oil(say u use esso) and thn the nearest esso is still far away and a shell is in front of u..would u go in?...or do u want to keep going just to use shell and risk stalling
no issue mixing oil brand and mixing 95 and 97....i sometime mix shell's 95 and 97 thn sometime full esso 95 thn sometime if holiday didn't go anywhere thn i pump petronas cuz its near
always like that..no issue also

dont use ron95 for modern car .. our ron 95 is same with 92+addictive  .. it was the gov who ask the fuel maker to come up with a low price fuel but better then ron92 .. old car carburator is ok to use ron92-95 -97 new car with fuel injection no no no.. did u notice they is a lot more car with their bonnet paint tearing off due to heat problem??

Lower RON fuel are more prone to pinging and knocking, EFI cars have knock sensors that can retard ignition timing to minimize knocking. But carb cars do not have knock sensors, and cannot adjust on the fly when pre-detonation occurs, therefore they are actually not suitable for lower RON fuel.

What you are suggesting is complete opposite.

use ron95 doesnt mean u car will develop problem right after u used it ... my point is after the intro of ron 95 more and more car is having an engine oil leak problem ... and engine oil leak will not happen in 1-2 years even if u are using ron95 .. but u will feel ur car engine not as good as before and after some while many engine related problem will started to arise...

my car, when started using 97, ron 95 was only launched this past 2-3 years right, my car 6 years. i cover 10k every 2.5 months sometimes less. but now, got another car already for my balik kampung trips, so now im clocking high mileage on my exora cfe, which btw, from day one,i have been pouring ron 95 as well. car already 16k . only 5 months old. no problems so far.
with the exora also, im a heavy footer, i get around 300km for 50 bucks.

I have been using Ron 97 all the while in my rusty car. Then when price went up, i started to use 95. Just need to calibrate the carbs and i'm good to go. Its already 3 years right? No problem so far. But i hate Petronas. 2 times i used this fuel for 1 week, it killed my fuel pump and clogged my fuel filter. Basically the fuel is too clean and abrasive. Old cars do not agree with it. The same thing happened again with Shell. I tried it because of Bonuslink. But have always been Mobil or Esso for me.

most car who have been using the ron95 since coming out from the supplier their car started to develop problem now .. first u will notice ur air cond not that cold anymore and ur car engine start to consume more engine oil and leaking oil...check out with ur trusted mechanic ask them since the intro of ron95 did he notice lot more car coming to have a top overhaul due to oil leaking?

Thanks for your reply. I haven't done my first service yet. I'll call the salesman tomorrow and ask what kind of petrol he recommends. Since the RON97 is cheaper now and the RON95 is that problematic. I think probably I'll start using RON97 for the next refill. So far for RON97 Shell is the best right?

my friend (from oil company) suggest to me that if want to use ron95 also can but every 2 full tank of ron95 use 1 tank of ron97 ...

and the forum topic is about ron95 caused damages... from my experience is YES ron 95 cause many problem and damage to engine.. even some on the internet related since the intro of ron95 more car caught fire on the road then previously .. this part i dont know ...

some will say no problem using ron 95 but that your experience lar.. at least i 'm not saying this person tok kok ..

but yet if u can afford to use ron97 then why have to use ron95 ? i myself use ron97 since my second car . my first car use ron95 change engine 2 times later sell ..

indeed ron97 is better then ron 95 if not then why on earth got so many fuel ron 92-95-97-100-101 ..

anyone remember the shell v-power racing which is selling at 3.10 perliter .. that 1 is ron100 and yet the price difference only 40cents from 97 to 100.. but yet 95 to 97 price difference is 70cents now..

yeah, but your point of long usage of ron 95 causes problems with engines doesnt hold water since i've been using ron95 on my dumb vanilla camtakpro gen2 for the past 3 years, and i've no oil leaks, in that 3 years, the car has racked in at least 100k,collected almost 2k in speeding summons and after 220k on the clock can still give a 'decent' 300kms for 50 bucks with 70% jam .
oil leaks and engine problems are usually due to not keeping up the maintenance of the car properly of being cheap on certain parts and ignoring the proper mileage change for wear and tear items as recommended by the manufacturer.

some choose to buy the cheapest engine oil in the market, and then whack a 10k oci. or for those who drives a jap, and their manufacturer oci is 5k, just because using a 200 ringgit fully syn oil doesnt mean the engine oci is now 10k, it is still 5k. the oci doesnt follow how expensive the oil we use, but follow the manufacturer spec.

some already notice some minor leak, but dont want to get it fixed. sometimes, its just as simple as changing the head gasket because, believe it or not. those things wear off as well. some choose to do engine wash ( when its not recommended by the manufacturer) . the engine super hot. go spray cold water on it. do it often enough, sure something will give away one...


i doubt ron95 causes engine oil leak and all the other problem...

well men like what i say u experience no problem on ron 95 me vise versa my first satria no problem before launch of ron95 that times only use ron97 .. no problem engine smooth no oil leak nothing ,, after ron 95 started using it after 1 years oil leaking gasket blow .... etc .. change engine after 1 years problem come again gasket not blow engine oil top up every 2 weeks.. my service is 5 k with semi synthethic shell . sell car ..now
my wife city also same problem service also not using cheap oil .. but semi syn oil on every 5k .
now used new car only use ron97 .. while that my experience .. maybe some will say both of my car got problem already .... but then i just want to use ron97 instead of ron95 give less problem ...before the lauch of ron95 ..

One thing I'd like to know is does RON97 definitely perform better than RON95 for long journey travel? I usually use my second car for working. I only use my c-class for weekend and outstation. After read what you said, I'll just go for RON97 since I don't really use my car daily and as long as it helps to keep the car safe from damage. Its definitely worth! yawn.gif

you will generally get better mileage when u use higher ron. if you dare, you can try pour 10 litres of v power racing, and then drive as you normally drive, and see what mileage you get before the empty tank light comes on. then pour 10 litres of vpower and do the same. then lastly pour their ron95 , same amount(10 litres) and check the mileage. U will notice that v power racing would give you the best mileage. ...biggrin.gif
for your c class; pour 97 lah since it only runs during weekends.

I havr covered more than 200,000km. My savvy has clocked 150,000km. 1st few years of ownership was using RON97 until gov introduced RON95. Engine still going strong and can achieved top speed. The only downside is FC worse a bit.

You sound like RON97 die hard fan as you give the budget till rm5 per litre which means you will never change to other RON. Your thread made me recall that sometimes my C-class likes chocking when speed up from 40 to 100+ when I get out from the petrol station in highway, I didn't reliaze any problem with it and I thought it was my driving style problem. Until now, I think it might could be the RON95 problem.

Do you even know what the RON number stand for? I can bet 99% dont even know what it is for. And to those idiot that say using RON95 causes your car to catch fire easier, please go shoot yourself in the head before you spread more of your stupid facts on the internet.

RON stand for Research Octane Number and it is an indication of the fuel's resistance to auto-ignition or better known as pinging. Pinging occur when the air/fuel mixture ignites prematurely in the cylinder before the piston reaches TDC. The higher the fuels RON number, the better the engine performance as the ECU does not need to retard the ignition of the fuel mixture too much to prevent premature ignition.

EFI engine have no problem as their ECU can auto-calibrate but carburettor engine might need to be retuned to take RON95.

No such thing as faster engine wear and tear if using RON95. But what I can see among all the fuel companies, BHP and Esso/mobil fuel perform best cause they add alot of friction modifier additive. Just a tip to save you money.

You can choose to continue being ignorant. No one is stopping you cause in the end, you are the one paying for the fuel. I work in the downstream Oil & Gas business so I know my facts. At least backup with facts and dont just rely on your gut feeling. I think I spoke too much, better to keep it to myself.

if you think I copy from Mr wiki, then so be it. I dont need to prove anything to people like you

You can choose to continue being ignorant. No one is stopping you cause in the end, you are the one paying for the fuel. I work in the downstream Oil & Gas business so I know my facts. At least backup with facts and dont just rely on your gut feeling. I think I spoke too much, better to keep it to myself.

now u say u work at what downstair of oil and research ??? ya spoke too much later get sack for telling much more about fuel ?

u say i choose to continue ignorant vise versa i also can say that to u . i'm happy with my choice but sad now cannot get ron100 on shell already not on my area..

nest times dont just come out from no where to say people are idiot and should bang their head ?? have some manners . u got ur believe i got mine .. i didnt boom those people who use ron95 saying they are **** my old car still using ron95 only my new car i use ron97 all the times ..

Wow suddenly this topic become hot again. Ok guys despite all the theories, do you realizes (some of u will shoot me for this question). Using Ron 95 your engine bay gets hotter? I meAn just stand infront of your car after a drive. U will be surprise to feel the very warm heat that I never experience before when I was using 97. I have been using 97 for a year. Then try out 95. No doubt 95 makes the the engine raw and no power and sometimes I can hear my engine pings. I have been using 95 for 6 full tanks. I can tell that 95 is not a pleasant fuel to drive. It just make too much noise and sluggish. In long run it may damage my car. After using back 97. Everything goes back smooth and normal. Oh yeah and the engine bay warm temputure. When back to normal. No more very hot sensation.

no idea about new car or old car having difference on RON. instead i know if you are driving a sport car then definitely got difference.been pumping ron95 since the first day i get my persona. Now 76k km. no problem at all. on my volvo 850, last time pump Ron97, since introduce ron95, i pump ron 95. same, no problem. only thing is both my persona and volvo choke on shell ron95. other is ok. Volvo is a 2.5 which seems to have better FC, using RON95 caltex/esso, fc is around 11km/l. RON97 i get around 12km/l. for persona, i get the same. but high end revving on RON97 is of coz much smoother. if RON95 will damage car, while previously our RON92 wont, why dont pump RON92?, coz we got no choice. minimum requirement of new car is RON95.

btw, about mixing RON97 and 95, i got experience on my persona only. Volvo never try. pumping RON97 on the volvo gonna burn my wallet. RON95 alone reach RM100.
Half tank of caltex RON95 and RON97 is quite worth if you wish to have RON97 running in your car.
i pump RM30 of RON95 and remaining pump RON97. i think RON97 is around RM50@RM2.70 per litre that time.
RM80 for full tank instead of RM60-65. A difference of RM15 to RM20 is actually acceptable. Power I wont say is powerful, but is smoother. Idle time, engine sound same regardless of mixing, pure 95, pure 97. High rev at 5000rpm and above, noise lvl is higher when using RON95 than mixing with RON97/ pure RON97.
So if you always drive at below 3k RPM, no point. I get same FC on all. RON97 caltex is recommended for high rev kaki. hahaha~~i tried shell 97, i got no comment. is not even better than BHP RON97. Unless is V-Power Racing. I never visited shell since shell fuel save 95 save 1 liter per full tank is introduced. 70 litres on volvo save 1 litre =="

i once saw an old article on the shell website regarding the launch of the first ever vpower... and it stated that by law...maximum RON in malaysia is 97.

so the Vpower racing is 97 with additional additives.

tried finding that article again so many times and still havent been able to find it...

Sometimes, when I drive my car (Myvi 2011 edition) during hot weather and dry condition, I kinda get these jerking feelings, like my engine was a little bit sluggish. Was it caused by RON95?

its cause ur engine is sucking in warm air which is less dense with oxygen. at night when air is cooler u can feel the engine perform better cause cold air is denser

Coincidence only happen after one year I used 97 only I feel it when switch to Ron 95? Wow ok. That's really a coincidence. Wasn't checking anything. I always clean wipe the engine bay after a drive back from A car wash. That's where the most obvious I felt it was really hot compare to Normal warm temp when I was with 97. Hm....coincidence? I don't think so. Well
This is just my opinion and experienced. No need to urge with it. If u don't have the same experience. Then good for u. Your car is great with
Ron95 ( our so called 95). Majorities knows is not pure 95

can any WRX owner can verify this low-compression EJ20 theory?

while mass produced engines from merc & bmw are generally low-compression as well(except AMG-tuned)
so they good for ron95,even merc stated their engine can use ron92 as well

Lol, u guys are just paranoid. I went to california previously, do u know that ron they have are RON 91, 92 and 95 (AKI 87, 90 and 91) only at normal pump station. And the price for ron95 is about rm5+- per liter ( around usd 5++ per gallon). They used it (ron92 midgrade and ron95 premium) on big capacity engine such mustang, cadillac, Camaro for everyday used. No problem pon. Only Malaysian think ron 91,92,95 is bad for car, even we just used it for cheap jap car. Duhh

My experience.. using mpv rondo 2.0 ... after the introduction of ron 95.. the performance is not that vroom anymore.. u have to feel it to believe it! in fact have to refuel often. ended up using my 1.5 wira to drive around. Personally there are some differences.

Will be purchasing elantra or tucson soon. Not sure want to use 95. ill keep my wira for that.

So many cars got burn nowadays.. and i do agree my wira is hotter than before...

First of all, it is not all about the static compression ratio. Compression ratio alone does not determine whether the engine pings or not. 4G63 compression ratio goes from 7.8 to 8.8:1 from the oldest to the newest and final batch of the 4G63 in the EVO 9. Subaru EJ20 maintained at 8.5:1.

It's all about the engine tuning. To squeeze more power out of the 2L engines, the Japs had to put very aggresive tuning and need to run it on RON100. They didn't make it run on RON100 just because they had RON100 fuel. Since the Japs don't give a damn about emissions control, they can tune it hard and run RON100 and spew shit out of the exhaust without anybody bothering them.

However, on export models and with strict emissions controls in US/UK, they had to use the EJ25 (2.5L) to produce the same power as 2.0L due to the less aggressive tuning and those engines are made to work with RON95 and below.

In Malaysia, the grey importers bring in JDMs and will ping when they use RON95. As much as the ECU wants to retard the settings, by default, it will always try to revert back to original aggressive programming and the engine will keep pinging. Those who purchased the export models from local distributor like Motor Image, can run their WRX on RON95 without any issue.

I run my UK model WRX on RON95 without any pinging since it was made to run at RON95 for export models.

We get our petrol from overseas too since we don't refine them all in Malaysia. We export crude oil but import refined petrol. I don't find anything wrong with our RON95 even with my turbocharged engine. What's wrong with your car?

then some will say ai ya car only mah got problem sell buy new car ..to me this is the most stupid response .. car is liability even if u are rich can pay cash on your car the next day u sell u will lose 15k at least lar.. got so many money to waste then pump ron95 ????

Why use RON97 when the car does not need it? Driving a sports car does not mean it needs RON97 unless you get a grey import JDM model. My car is made for a country that does not sell RON100 and runs on RON95 as per the owners manual. All new sports cars nowadays exist in both JDM and export models and both are tuned differently. Gone are the days of people driving an EVO 6 in UK/US trying to hunt down petrol stations that sells premium RON 98.

We get our petrol from overseas too since we don't refine them all in Malaysia. We export crude oil but import refined petrol. I don't find anything wrong with our RON95 even with my turbocharged engine. What's wrong with your car?

mind i ask you, how u know the car parts spoil due to the petrol RON rating 95 or 97??? my other car use ron 95 for 10 years no problem so far.... then now new car still using ron 95 . still same no problem.

for me normal car use ron97 is such a waste.... they use ron97 due to they can use a more agressive mapping to let the engine produce higher power. if your engine is compatible with ron95... u pump 97... got what diff??

thats the thing bro, many are disputing the fact that you related your engine troubles with the petrol you pump ? might be how you mantain your car ? or you might need to change your mechanic ? i know my brother had issues with his cars, and he had both a local and a jap. i took one good look at his engine bay and i can identify many wrong things. told him to bring his cars to the mechanic i send mine too, and after the fella work on his cars, my brother now no complains. the engine runs well, is quiet and he postponed selling his local car to a few more years. he is even happy with the work the fella did on his jap car.

anyhow, no one stopping you from pouring ron 97 , but i would suggest that the next time you get engine troubles, try get an opinion from a few shops before fixing your car.

one thing to ponder...have it ever occur to u that the life span of the gasket or oil seal or whatever just happen to reach its limit when ron95 was introduced?

u did mention u travel a lot...

if ur point is ron95 perform poorer compare dto ron97 then that makes sense...to blame ron95 caused damage to the engine well there's no solid fact or thorough test done to justify wasn't it?

car burnt a lot nowadays...i wonder why nowadays with the introduction of so many accessories so many kedai abang like accessories shop...we've got now the famous drl, the f1 3rd brake light style, LED all over, HID amplifier crossover blablabla u name it...it only needs one wrongly installed by amateur and it could make the wiring gets hot and trigger sparks at the battery area which COINCIDENTALLY resides in the engine bay and somehow near the petrol or engine combustion area and kaboommm people wont blame the wiring they blame the petrol instead...

got what i'm trying to point out?

oh well i'm no genius i just think what might be logical...i can be wrong so suit urself...as long as ure happy with ur ron97 and others are happy with their ron95 why bother?

just my piece of thoughts...

i dont buy wat u and your mechanic talking ....

unless u are talking u driving a car need RON 97 , but u use RON95 all the time, so cause SERIOUS knocking. then this is other story, cause it can cause engine damage.

do you have any idea what RON rating about??

i always ask those people who pump 97 for their car.... some of them answer to me... RON95 oil dirtier than RON97 rclxub.gif rclxub.gif rclxub.gif

I would say most of the ppl would have not encountered such problem as yours.
you give out very big amount of information that can beat your own statement.
You travel a lot before the launch of RON95. When you started using RON95, hello, your car is at much higher mileage. And a local 2nd hand car that is used for 5 years. Come on. We all know our local car is not that reliable, but you have been driving a 2nd hand local car with 5 years without problem. you put the blame on petrol rather than your car or parts. is just like you rather believe that your new handphone charger damage your phone rather than thinking about the age, reliability and other factors.
No one is stopping you from pumping RON97. We are only telling you that it is not necessary to use the money. why would Car manufacturer want to cheat you on the minimum RON required for the car. the testing and tuning of the car is run on that particular RON and sold to the people. And are you thinking that they use overseas petrol to tune your car and when you pump the same RON95 you get a fake RON95??
it is like saying that the I-phone in US is better than the I-phone in Malaysia. I think that is what you say.
go ahead and use ron97 for your new car. but please make sure the mileage of the car and the age of the car is the same as the car you encountering problem before you say that RON95 really damage your car. dont come and tell us that your new car after using it for 2 years got no problem because using RON97. Your old car is more than 5 years car when you using RON95.

*
so both local and japanese car leaking engine oil, become hotter, and aircond got problem??
come on. since you are so confirm that the car problem comes from RON95, why you did not service the broken part and never to use RON95 again?? if you are able to confirm that it damage your car, you are just being too clever at your own statement. You mention that you rather pump RON97 than spending the money to fix your car. but then you still let your old car use ron95. are you saying that your old car dont need servicing and repairing?? if yes, you should use RON97 on your old car. I cant believe someone that can be so certain of something damaging its own car but still willing to spend the money to repair. As you said, you dont buy car and sell car every 5 years because you dont gain. so as you are so confirm RON95 damage your car, you should start pumping RON97 for them. then you can use your car without problem. as you are so confirm that it is RON95 that make your car have those problem, you will not have those problem anymore.

Btw, you should share where is your mechanic, so that i wouldnt mistakely go there. He is more pro than those engineer in car manufacturing and petroleum.

Seriously one question, you think your satria will not have any problem you encountering now if you use RON97 all the while??

Hi, I'm not sure whether has this topic been posted here before. I have been hearing stories about how bad RON 95 is. People been telling me that this petrol will easily caused car catch fire. This is why now days we have been seeing and hearing allot of car caught fire. I realized that allot of car caught fire victims ever since RON95 been introduced.

I even hear stories like our Ron 95 is not a real 95. It was from the ron92 that added addictive to produce like Ron 95 which can harm the car engines and parts.

I was using RON95 for my Honda city for about 6 months and my car slowly develops problems. Problems like throttle body and throttle sensor making my car chocking.  Car behaving weird and when sent to HONDA, the machenIC told me not to use ron95 as it will wear out car parts and damage easily. I experienced difficulties of gear shift. Feels like it dO not want to shift to the next gear, lagging or something. The engine raw. It's louder than before and felt lack of power. So when mechanic advice to use rOn97. Everything works find now. Gear shifting is smooth and no more weird behavior like car chockIng engine dying. Engine is quieter like before.

I would like to hear what are your opinions

Whatever you mention about are about "what you heard".

I've been using RON 95 in my both cars since RON 95 launched in Malaysia in the past few years, no issue with them, except less power and responsive.

they should just cancel the RON95, instead the subsidies replace to RON97 but with frequent price change due to market price, but the subsidies still apply on it.. better? right?

hmm i just got my license and now starting to drive a myvi given by my mom, i find that the car is now getting sluggish when i drive for more than 20min, 0-40 is freaking slow (esp when u stuck in traffic jam just to get it to 20kmh is slow) and when u wanna potong ppl u must kaki kuat then only u get the power.. and when im driving ard 60-80 by tapping the throttle slowly it feels the car is like tired very tired no energy to pump.. could it be due to ron 95. i feel my gear changes slower (like no energy) every time. could it be due to ron 95? maybe the next pump i will try ron 97 if the fc improve

anyways OT abit. does it mean that the fuel faster finish (95 vs 95) means the fuel is cleaner?

The only problem you get from using the fuel with a RON rating that is too low for your engine would be detonation/pinging/knocking. The result of that in the long run would be damage to your piston/conrod and possibly crankshaft as these are the only things which would be directly affected by detonation.

Anything else that spoils is not related to the fuel. Any good mechanic can tell you that. Your mech is just not good enough if he blames your spoiling air con to bad fuel. That is like saying the wrong tyre caused your windscreen to break. It has no relations whatsoever.

Err... for non-new cars, may give a try on the carburator/fuel-injector cleaner (that mix with fuel), the product suggest 1 bottle for every lubricant oil change. I feel the difference after applying it (maybe too much dirt after 10-years), though the feel is very subjective.

Not sure if the liquid will cause warranty void for new car.

of course my mechanic not saying to me ron95 cause aircond spoil lar.. u already give out the answer .. bad ron cause denotation .. will bad detonation cause engine tempature high? my point is when ur engine tempature is high the first thing u will notice is ur air cond not cold ..

Nope u don't, but then again, this is an anonymous (almost) forum, so post whatever u like. Let the misguided fools believe whatever they want also... hahaha

RON95 in Malaysia may be bad for some engines, but will not cause some of the damages described. Like car paint become bad because using RON95... this one classic joke. rclxm9.gif

Nope u don't, but then again, this is an anonymous (almost) forum, so post whatever u like. Let the misguided fools believe whatever they want also... hahaha

RON95 in Malaysia may be bad for some engines, but will not cause some of the damages described. Like car paint become bad because using RON95... this one classic joke.  rclxm9.gif

hahaha... since you are so pro here.. maybe u can solve this question.

When you are re-building a race engine that has been re-machined and you need new crankshaft bearings.
How do you purchase the correct one from the spare part shop. What must you specify to the guy when you purchase it?

Can you prove otherwise?

Stop calling ppl out because they can't prove that RON95 is in fact RON95, when you yourself cannot prove your own claims with evidence other than "your engine develop problems after using RON95.".

Hi, I'm not sure whether has this topic been posted here before. I have been hearing stories about how bad RON 95 is. People been telling me that this petrol will easily caused car catch fire. This is why now days we have been seeing and hearing allot of car caught fire. I realized that allot of car caught fire victims ever since RON95 been introduced.

I even hear stories like our Ron 95 is not a real 95. It was from the ron92 that added addictive to produce like Ron 95 which can harm the car engines and parts.

I was using RON95 for my Honda city for about 6 months and my car slowly develops problems. Problems like throttle body and throttle sensor making my car chocking.  Car behaving weird and when sent to HONDA, the machenIC told me not to use ron95 as it will wear out car parts and damage easily. I experienced difficulties of gear shift. Feels like it dO not want to shift to the next gear, lagging or something. The engine raw. It's louder than before and felt lack of power. So when mechanic advice to use rOn97. Everything works find now. Gear shifting is smooth and no more weird behavior like car chockIng engine dying. Engine is quieter like before.

I would like to hear what are your opinions

Dunno about u... I have been using RON95 since introduction. Only recently my car started having e-throttle problems after switching back to RON97.

When you dont know how the oil industry work, better to just keep your 2cent to yourself. Fuel formulation is subjective and dependent on different oil companies and we dont add additive to boast RON92 fuel to RON95.

Not only it is more expensive to do so, its completely stupid to produce RON92 fuel and then later
add additive to boast the octane number. Doing so would make your fuel product inconsistent, not to mention the extra hassle. Daily production for a typical refinery runs up to millions of barrel per day and each barrel is around 42 gallon.

i don't think ppl are not happy about you using RON97. No one give a damn on your money. Is just that facts are to be proven. We talk based on facts. Prove is the most important thing. If i tell you an asteroid will hit the earth tomorrow, will you believe me? i got no prove to show you. But if an astrology say that, the whole world will be panic. because they can give out solid prove.

And everyone knows detonation is not good for the car. but then is your car already tuned to run on RON97 therefore RON95 cause detonation to your car. then we can understand why it cause damage to your car. if not, tell us what is the symptom you get during knocking, tell us how do you know there is detonation happen insideyour engine. ?
you think RON95 comes into malaysia because the government do so??
please do some reading. you have internet access. I don't like the government and i believe quite a number of people dont like too. We know they cant be trusted anymore. but then, this RON things got nothing to do with them.

I am just thinking that you are not satisfied because your satria started giving you trouble after 5 years of owning i suppose.

dont believe, try on your aircond during coldstart. compared it with your car still having the warmed up temperature.

This thread is a waste of space. Reading some comments really give me brain damage.

RON95 is gonna stay no matter whether you change the government or not. It is not simple to change the formulation and it is not an overnight process. No doubt the technology is there and we can even refine it up to RON99 just for the lulz but why do that when fuel prices in malaysia is controlled and fixed. RON99 is not gonna give your crappy city car a 20 hp boast or what. Its a waste of money to refine it to RON99 when 90% of car cant utilise the fuel.

If you are so paranoid about RON rating in your fuel, you can go add benzene,toluene or xylene in your fuel tank yourself. Your fuel RON would be boasted up considerably.Benzene has a RON100 rating. But mono-aromatics(benzene,toluene,xylene) are toxic so you bare the responsibility yourself.

theoratically no. but try stepping the accelerator on idle when you entered the car in a hot weather. it will cool your car much faster. Is because your engine is providing power where some power are sucked by the aircond compressor. so if your engine is running at the ideal temperature, you will have colder aircond. you can go and make your car temperature very low, but then why they dont do that? think man. with nowaday technology, cooling the engine is not that hard for engineers. but dont you realise why most car have almost the same temperature when they are normall. and for you to know, my volvo have poor acceleration, bad gear shift, and jerking when the car is too cold.
Ok, maybe i used the wrong word. it does not mean that if my car temperature is higher than normal i got colder aircond. that is no no.

Oh my farking god.

I read 2 pages of this thread and am completely astounded how completely ignorant some people are and yet claim to be 'well informed'. Thank god for the smarter few towards page 10/11/12 otherwise LYN discussions will be going down the drain.

Claiming RON92 + additives and later selling as RON95 is pure stupidity. Oil & Gas companies don't have shit for brains as some forummers do. Additives cost more than the base oil to make the petrol so it wouldn't make dollar and sense to sell RON92 on steroids and not to mention the lawsuits that'll follow filed by people who'll claim false advertising or something. Vpower Racing is RON97 + additives. Why is Vpower Racing so much more expensive? Because of the additives.

Jeez.

And RON95 causes detonation??????????????? Do you even know how an engine works? Ignition timing specifically? Or for that matter do you know what detonation is?? Or are you just trying to sound smart because you're coming across as a wannabe ignorant fool. Stop saying stupid things while you still can.

Let me ask those who think RON95 spoils their engines a simple question, do you know what is compression and how it affects the engine?

In M'sia, apart from exotics, only a few "affordable" cars must use RON97 otherwise they'll get knocking big time. The Civic type-R, Megane-R, Suzuki Swift Sport and any high compression engine car.

As for hotter engine - colder aircon, there is logic to this statement. When the engine is hot, the fan is turned on which effectively cools the coils and radiator therefore making the aircon colder.

its hard to believe that this is the only reason there's a lot of fire going around. Pretty sure the lack of awareness/maintenance from people is one thing.

Although I won't deny that Ron95 can cause damage to our engines. We've been running Ron 97 for many years and a couple of years ago 95 was introduced to our "already running on 97" cars. Its like changing a lower quality spare part and expecting the same result as the better product.

dude, US of A still using RON91 but never heard they have engine problem due to the RON they use. They even run on high powered car like EVO and what I've read from their car magz, a 400whp EVO8 running on RON91 without issue. The key is tuning.


Added on August 2, 2012, 2:12 aminb4 their RON91 is higher grade which match with our RON97

Using RON 97 for Toyota Hybrid cars is even useless since most of the torque comes from the electric motor. The engine is mostly for charging and less for power.

Although I won't deny that Ron95 can cause damage to our engines. We've been running Ron 97 for many years and a couple of years ago 95 was introduced to our "already running on 97" cars. Its like changing a lower quality spare part and expecting the same result as the better product.

I would love to see the evidence proving that RON95 can "cause damage to our engines". Because then I can sue the company I work for and earn millions in cash and live a fat happy life forever.

Please understand RON first before making general statements like that which make you look ignorant.

There is a reason why Singapore only allowed Ron 97 to be used no?
And I've also heard from people saying Ron 95 will kill the engine faster, but what to do?

Ron 97 price hiked like crazy in just few years time. sad.gif Everybody who had no choice must resort to Ron95, the cheapo petrol at the moment...
*
Who said Singapore only sells 97? They used to have 92 but that later changed to 95. 97 and some stations have 98.



AIYO.. this is getting tiring. USA still uses RON92 and below. If not mistaken the "regular" they talk about is RON88. "Premium" is RON92.

Petrol is petrol. How it burns is what is important. RON95 is easier to ignite than RON97. So fiddle with your ignition timing if you experience knocking. Otherwise please shut up and save yourself embarrassment from saying RON95 destroyed your life. The only petrol that is truly different in M'sia is Vpower Racing. Why? Because it has a lot more expensive additives. Oh btw, it's RON97 too in M'sia. In Singapore it's RON98.

Anyone else claiming RON95 destroyed their aircon/engine/tyres/power windows/etc will get more trolling from the truly knowledgeable ones here so please go do some research first before claiming RON95 destroyed your car.

Like I said in my earlier post, unless you own a HIGH COMPRESSION motor, RON95 will do nothing to do your car unless you have a fuel hose leak... then that will guarantee you'll burn with your car and do us all a favour by removing you from this thread.

Is there a solid proof that saying RON95 will cause damage to the car.
Our car still works fine with RON 95 (pump in at Petronas station). My neighbor 54 old uncle, driving his old Datsun still alive with it till today.

Heh. If the new generation car cannot handle with this fuel, this merely being a joke.

For gasket blow, i think it is more related to fake lubricant oil. Aircond not cold, maybe related to aged compressor/gas leak/hot environment with low-power compressor.

The one damage the engine is the fuel sulphur content, not the octane, unless the ignition timing is incorrect, causing extensive knocking to cam/cam-shaft, and hence cam damage and power lost.

One possibility is the sulphur content in RON97 is less then RON95? I'm not sure...

OK hahaha you guys are jokers....

ok let me put it straight... yes compression ratio affect the RON rating

see here

http://en.wikipedia.org/wiki/Compression_ratio

the calculation is

user posted image
= cylinder bore (diameter)
= piston stroke length
= clearance volume. It is the volume of the combustion chamber (including head gasket). This is the minimum volume of the space at the end of the compression stroke, i.e. when the piston reaches top dead center (TDC). Because of the complex shape of this space, it is usually measured directly rather than calculated.

So this means a engine with compression ratio of 11.1 to 1 is safe to run on RON87

now lets look at our car Compression ratio

Honda City : Compression Ratio 10.4 (http://honda.com.my/model/overview/city/)
Honda Civic (NEW) : Compression Ratio 10.6(1.8l) 10.6(2.0l)
Honda Civic FD2r (Type-R) : Compression ratio 11.7 (Not RON 95 safe) USE RON97

Toyota Vios : Compression Ratio 10.5
Toyota FT86 : Compression Ratio 12.5 : 1 (not RON95 safe) USE RON 97

PROTON engine
Campro CFE engine : compression ratio : 8.9:1 to 10:1 (CPS retard the timing to 8.9 lowest)
Campro CPS engine : compression ratio 10:1

Myvi 1.3 : compression ratio 10.0:1

so we can now say it is safe to use RON95... wait wait how about old car before RON95... hehe

Proton Wira : Compression Ratio 9.2:1 (Safe for RON92)
Proton SAGA (The original SAGA) : Compression Ratio 9.5:1 (Safe for RON92)

remember when saga come out we only have RON91 and RON 92 the car need to be compatible with it... also that time Thailand only have RON88

so now who going to dispute the formula from wikipedia and our car will spoil in RON92...

MOST OF OUR CAR CAN RUN ON RON88 for GOODNESS SAKE!!! stop wasting money and let the rich waste money!!!

I think you think too much. It wont affect your gear box la bro. Doesn't make sense at all. Use logic instead of "i think my car... no power la... bla bla bla...." Give your car service regularly, gear oil, engine oil and etc.

He's asking how you come to the conclusion that compression ratio directly determines the RON usage. The site does not explain that because compression ratio is just a static component measured at TDC. Static compression ratio alone does not determine the RON usage.

Ignition timing plays a bigger part as the more aggressive the timing, the higher the RON is required to prevent detonation even though there is no change to the static compression ratio.

As for CPS lower compression ratio, that is not due to reduced timing as stated by you.

QUOTE
Campro CFE engine : compression ratio : 8.9:1 to 10:1 (CPS retard the timing to 8.9 lowest)
Campro CPS engine : compression ratio 10:1


Every engine can only have 1 static compression ratio as that is determined by the shape of the piston. In the CFE, the piston is changed to reduce the compression ratio from 10.1 to 8.9 without changing the length of the conrods. Ignition timing DOES NOT change static compression ratios. Therefore the campro CFE static compression ratio is 8.9 and not a variable 8.9 to 10.1. THis is static compression ratios we are talking about, not dynamic. That would be another story and another topic.

The tric to reduce compressio ratio is directly invilve in variable timing where the valve maintain open in the inlet to have flow back hence reduce compression ratio and save fuel each piston has a fix compression ratio but by retarding the inlet valve longer the mixture will flow back and reduce the compression ratio hence this is how knock sensor work.

Then you are talking about dynamic compression, not static compression anymore. Just like how a forced induced engine has a much higher dynamic compression ratio even though it has a lower static compression due to the fact that more air and fuel is forced into the combustion chamber. However, this does not change the fact that the STATIC compression ratio remains the same throughout the whole process.

It is not a trick. It is your lack of understanding what Static and Dynamic compression ratios are. You do not change static compression ratios by changing valve timing and lift duration.

Yes agree with you the compression ratio pretty much remain the same since the cylinder length is the same (unless some genius invent variable cylinder length management haha not possible)

Alot of new car come with hi tech stuff to varies cylinder / varies valve / retard ignition / and with the new Prius engine even make a normal otto cycle engine become atkinson engine.... simply by playing around variable valve / retart the valve / etc etc

Yes but we are not talking about those engines are we? The word STATIC means non-changing. If an engine has changing ratios, they'd most probably call it..Variable Compression ratio (yes thank you captain obvious..)

And your reference again to otto cycle engine is still not related to STATIC compression ratios. That is dynamic compression ratios.

Please understand the fact that the calculation of the static compression ratio comes from simple volume mathematics. Don't look at the formula in wiki as that would confuse you into thinking that CRs are complicated stuff. It is just a simple volume of the whole cylinder when the piston is at BDC (bottom dead center) plus the volume between the piston and engine head at TDC divided by that same volume again at TDC.

Once you understand that, you will realise that no matter what you do with cams/lifts/valves/duration/etc etc, you will never change the Static CR. Confuse yourself Static CR with Dynamic CR.

Ignition timing plays a bigger part as the more aggressive the timing, the higher the RON is required to prevent detonation even though there is no change to the static compression ratio.

As for CPS lower compression ratio, that is not due to reduced timing as stated by you.
Every engine can only have 1 static compression ratio as that is determined by the shape of the piston. In the CFE, the piston is changed to reduce the compression ratio from 10.1 to 8.9 without changing the length of the conrods. Ignition timing DOES NOT change static compression ratios. Therefore the campro CFE static compression ratio is 8.9 and not a variable 8.9 to 10.1. THis is static compression ratios we are talking about, not dynamic. That would be another story and another topic.

i think it will make it worse... normal people will accelerate harder if the car is underpower thus consumes even more fuel doh.gif

I do agree that different brand on ron95 makes a difference. My old (>10years) car has less knocking with caltex (more fueal save)/esso compare to previous generation petronas ron95, then I stick to caltex ever since. I think the current petronas ron95 has improved as i just tested with other old car, smooth though but forgot to calculcate the milage...

Wow suddenly this topic become hot again. Ok guys despite all the theories, do you realizes (some of u will shoot me for this question). Using Ron 95 your engine bay gets hotter? I meAn just stand infront of your car after a drive. U will be surprise to feel the very  warm heat that I never experience before when I was using 97. I have been using 97 for a year. Then try out 95. No doubt 95 makes the the engine raw and no power and sometimes I can hear my engine pings. I have been using 95 for 6 full tanks. I can tell that 95 is not a pleasant fuel to drive. It just make too much noise and sluggish. In long run it may damage my car. After using back 97. Everything goes back smooth and normal. Oh yeah and the engine bay warm temputure. When back to normal. No more very hot sensation.

now my old car still use ron 95 bcos already know what need to service every year before the problem come out..

new car no ron95 ron 97 all the times .. u say it a waste to use ron97 if the car can use ron95 . not for me .. i rather pay extra now then have problem later that all .

For me quite the opposite wor..RON 97 is very damaging to my tyres..wears off faster...only last for 3 months, and my tyres also catches fire due to the friction , RON 97 very powderfull..if using ron 95 can last 6 months..no power ma..sluggish.. rclxm9.gif rclxm9.gif rclxm9.gif

When I use RON97 my car become so powderful it actually make the earth spin faster when I drive causing shorter days.

After much calculation I've found that on average it will shorten the day by 4 minutes 8 seconds, increasing the Earth average rotational speed from 1669.8 km/h to 1670 km/h.

So please use RON95, otherwise we end up with 20 hrs day if everybody use RON97.

As mentioned many times before, if your ECU can adjust the ignition timing automatically then you may feel the difference using better RON fuel (burn more efficiently) hence more performance...

Using lesser RON = that may cause pre-mature combustion aka KNOCKING / PINGING and normally in modern engines the ECU would auto retard the ignition timing to prevent your engine destroyed itself.

Well said, bro. Too many InterNerd mechanics with WikiPhD scrolls embedded in their flash - based HDD lolz. I'm very sorry but I don't understand why many people complaining about lack of power when they use RO95. Power for what? Overtaking? Just downshift the gearbox will give you the thrust for overtaking, either manual or automatic cars. Other than that, personally for me, just gradually raising the speed to 80 - 90kph, then maintain it enough already. AES sudah start mahhh, and I'm still trying to find a way to beat it lol, which is only possible if one drives at the speed limit and lower kekekeh.

I would love to see the evidence proving that RON95 can "cause damage to our engines". Because then I can sue the company I work for and earn millions in cash and live a fat happy life forever.

Please understand RON first before making general statements like that which make you look ignorant.

Who said Singapore only sells 97? They used to have 92 but that later changed to 95. 97 and some stations have 98.
AIYO.. this is getting tiring. USA still uses RON92 and below. If not mistaken the "regular" they talk about is RON88. "Premium" is RON92.

Petrol is petrol. How it burns is what is important. RON95 is easier to ignite than RON97. So fiddle with your ignition timing if you experience knocking. Otherwise please shut up and save yourself embarrassment from saying RON95 destroyed your life. The only petrol that is truly different in M'sia is Vpower Racing. Why? Because it has a lot more expensive additives. Oh btw, it's RON97 too in M'sia. In Singapore it's RON98.

Anyone else claiming RON95 destroyed their aircon/engine/tyres/power windows/etc will get more trolling from the truly knowledgeable ones here so please go do some research first before claiming RON95 destroyed your car.

Like I said in my earlier post, unless you own a HIGH COMPRESSION motor, RON95 will do nothing to do your car unless you have a fuel hose leak... then that will guarantee you'll burn with your car and do us all a favour by removing you from this thread.

Using RON95 for my Proton FLX 15mth old (13k KM). Enging sound is getting louder. Even can hear it from 10 car away these day.
For slow driver just want to move from 1 place to another place, RON95 is good enough.
For driver dont want to spent more time on the road or efficiency drive. RON97.
Quality is different. RON95 need to step harder on fuel paddle which in return will stress you engine which causing the loud engine sound.
Lots of my friend using RON95 but friendly speaking, they prefer RON97 but due to the COST, no choice.

I did a little experiment and filled up with RON95 instead of my usual 98 a while back.

Except for a little hesitation at the start when the ECU tried to control the knock levels, there was no difference after I went for a long WOT run.

As I always say, the ECU will compensate by retarding the timing. If you aren't knocking, you're fine.

I would love to do this. But it would be quite redundant and expensive.

Most modern cars these days need time for the ECU to adjust to the octane differences. Pump in RON95 and give it a day or 2 to adapt. Go dyno.

Then when almost empty fill with RON97 and drive around until it's almost empty then fill up with RON97 again. Go dyno.

That way the ECU will have plenty of time to adapt and it'll be close to fair depending on the conditions you go for the dyno.

These days people think the ECU adapts instantaneously... it doesn't unless you reset it and force it to relearn there and then or program it (if possible) to utilize the octane differences.

Actually the ECU will adapt very quick based on the feedback from knock sensor. To simplify, this is how it works: the ECU will take a step forward towards the knocking point in every combustion cycle until the knock sensor detects a knocking then it will take a few steps back in a cycle. After that it will take a step forward again for every cumbustion cycle until knock is detected again. This process will be repeating again and again.

How it adapts to a lower RON: it detects a knock and take a few steps back, then when the knock is still detected, it takes another few steps back until knock is no longer detected. After that it will take a step forward again in every cycle until knock is detected again and it takes a few steps back.

no problem using ron95 for all my cars.

I wish I have a car which can only accept ron97 or else that car will have problem. But... I can't afford that kind of car...

If I live in Thailand, surely I will use Ron97... Ron95 around rm3.60. Ron97 should be around rm3.80.. 20sen for more performance, no problem. But in Msia... no way i will use 97...

This issue has been discussed many times. Let me share some points for you guys.

Alot of that so called 'difference' that ppl experience between Ron 95 fuel and Ron 97 is actually psychological. You may see some minor difference but no where worth the price ure paying for Ron 97 currently. The slightly better mileage (if any) will be easily obscured by the much higher cost of the Ron 97 fuel. Please be reminded that Shell Ron 97 is not Shell V Power Racing.

Using a higher octane fuel will not make much difference to internal carbon formation. Its actually a waste to use high octane fuel when your car only needs a lower grade. You wont get much difference in mileage or engine performance. The truth is that every grade of fuel has cleaning agents. Too much cleaning agents, some say, can actually damage your car.

Octane is a measure of how much the fuel can be compressed before it spontaneously ignites. Only engines with higher compression ratios take advantage of higher octane gas.

http://www.ftc.gov/bcp/edu/pubs/consumer/autos/aut12.shtm

Another interesting article:

http://www.fraudguides.com/tips/june2.asp

So guys, please stop using Ron97 fuel. Its a complete waste. If u really insist on using, then limit yourself to 1 full tank every 6 months just for a 'clean-up'. Again, i dont think its neccessary

Btw, i did tests before between the Ron 95 and V Power Racing (not V Power 97) and there was a slight increase in acceleration. But with V POwer 97, there was no such noticeble difference. But V Power Racing is RM 3.30 right?

The car manufacturer would be the best advisor in this case. We can assume the compression increases but again it will be the car manufacturer who will specify a suitable fuel that maximises the performance benefit by using a higher octane fuel. If the car manufacturer has only specified Ron95 as the required fuel, then using Ron 97 is a waste. Like i said earlier, any slight difference (if any) will be insignificant compared to the much higher cost of Ron 97 fuel. Is it worth paying RM66 extra per full tank for this 'slight difference'? Thats RM 1,584 extra per year assuming you fill 2 tanks per month. So instead of spending RM 2,736 per annum, ure gonna spend RM4,320.

The problem with most ppl is that they think the performance increase (if any) will be significant and most of the time its just quantified by word of mouth rather than any hard facts

From experience, Ron97 gives me around 4-5whp more when I did my dyno runs at GT Auto in my old ride. Not worth the extra amount for Ron97. So rather have a tweaked ECU map to run on Ron95 instead for the power hungry.

But nowadays very poor, just pay RM1.80 for diesel tongue.gif

Although the octane reading may be same (Ron 95) but the additives from each manufacturer could be different thus creating such scenarios. Some say Shell 95 creates such problems while others claim Petronas also has similar issues. But there are others who say both these fuels are ok. So i guess it differs. Ive tested Caltex, Mobil and Shell and ive not noticed any difference. I only noticed a difference when using Shell V Power Racing but not V Power 97.

Plus we also gotta take the age of the car into consideration.

But in terms of power and acceleration, there would only be very marginal differences (if any) using Ron97 for a car designed for Ron 95. Either way, i dont think its worth the extra RM 1.00 per litre ure paying.

Either way, i think the new BHP Ron 95 Infinity Advance 2X would be a better choice at a cheaper price. Im just trying my first full tank this week.

car engines ignition timing will be retarded when knocking happens due to highly combustible low octane fuel, such as RON92 or RON95. retardation of ignition causes less power. this is why racers usually advance the ignition timing to get more power. also too much retardation on the ignition timing indeed DOES cause harm to certain engine parts, commonly is burnt exhaust valves.

so its true as some earlier posts say, save gas money, possibly increase engine wear

Firstly, are you refering to high performance cars? If not, which car in particular are you refering to? The topic of discussion i believe is normal day to day passenger cars. Secondly, is the car designed for Ron 95 or Ron 97?

all cars has a range of octane rating that the engine can consume.
eg a vios can go as low as 93. but it will perform better at 95, or 97.
the "car designed for Ron XX" figure is the lowest it can go without dying on u

How do you know a car specified as Ron 93 compatible will perform better using Ron 97? We're not saying that cars cannot operate on higher octane fuels. The question here is:

1) Is there an actual significant increase in power and performance using normal Ron 97 fuel in a car specified for Ron 95?
2) Does this difference (if any) warrant the extra price we're paying for Ron 97 fuel long term?

What do you think?

Unfortunately, for most road cars, the ECU is only self adapting downwards. It will not increase the aggressiveness of the ECU if you give it better fuel but it will retard to protect itself if there is something wrong with the fuel.

Therefore pumping better fuel into an ECU programmed for RON95 will not give you increased performance. I have tested this with my own car. If I don't change the baseline settings and leave it at OEM factory, even if I pump RON 97, it won't increase the aggressiveness on its own. Human intervention is required.

The only way to increase performance is to change the baseline settings in the ECU for a more aggressive setting. I'd pump RON 97 and keep increasing the aggressiveness of the ECU until it starts to retard on it's own and then download the logs to monitor (I don't like driving with the notebook connected to the OBDII port) and fine tune the settings. That was when I was a noob until I found the hundreds of ECU map available that were dyno tested and I could download them for free into my engine. Now no not much testing needed. Just pick and choose the map I want.

This is the reason why most cars don't get a performance boost when using better fuels and only retards on bad fuel as the ECU is made to tune down and not up.

Does that mean, god forbid, if I ever pour RON 92 into my engine, it will run on a retarded timing that is suitable for 92 even if I pump 95 or 97 later?

It will adjust downwards but I didn't say it will stay there permanently. It will adjust back to factory default but most will not go above that.

It most probably wouldn't even affect the engine. Unless you have a high tuned or high strung engine, the lower RON will not even affect it as the ECU mappings might be so sedate that a lower RON will not cause any pinging at all. Highly tuned engines are more sensitive to RON levels than those engines you find in normal cars.

Hi, I'm not sure whether has this topic been posted here before. I have been hearing stories about how bad RON 95 is. People been telling me that this petrol will easily caused car catch fire. This is why now days we have been seeing and hearing allot of car caught fire. I realized that allot of car caught fire victims ever since RON95 been introduced.

I even hear stories like our Ron 95 is not a real 95. It was from the ron92 that added addictive to produce like Ron 95 which can harm the car engines and parts.

I was using RON95 for my Honda city for about 6 months and my car slowly develops problems. Problems like throttle body and throttle sensor making my car chocking.  Car behaving weird and when sent to HONDA, the machenIC told me not to use ron95 as it will wear out car parts and damage easily. I experienced difficulties of gear shift. Feels like it dO not want to shift to the next gear, lagging or something. The engine raw. It's louder than before and felt lack of power. So when mechanic advice to use rOn97. Everything works find now. Gear shifting is smooth and no more weird behavior like car chockIng engine dying. Engine is quieter like before.

I would like to hear what are your opinions

Sorry if my post is too late, as I was just looking around the forum, I stumbled across this thread and I would like to share that my car after 2 years of using Petronas RON95, is choking actually. Went to the service center, they clean the throttle body but there is still intermittent choking.

I don't really believe in additives, but somehow just a few weeks ago I bought a bottle of STP Petrol Injector cleaner and somehow it was marvellous after a few days of running, immediately the engine became smoother and quiet.

But RON97 being gold prices, now using BHP95 and it seems okay, I think most of our RON95 petrol builts up carbon and such.

Agree injector cleaners help a lot, I experienced a big difference when starting my Mitsubishi. engine so smooth after service. no more rough idling.

Food for thought my 2004 Subaru runs smoother on Mobil RON91. People should include a list of what fuel is best for their cars.

Having owned a few cars, I have avoided using Shell. I find Caltex and BHP generally are ok.

Did you check your fuel filter? Engine choking are usually the signs of a clogged fuel filter and by putting something like a fuel injector cleaner, you are actually not just cleaning the injectors, you are also cleaning some of the gunk collected on the fuel filter. I have seen this happen many times and the symptoms come back after a while unless the fuel filter is changed. Always use a fuel injector cleaner only after you have changed the fuel filter, otherwise the injector cleaner has to go though a dirty filter and end up cleaning the filter instead of the injectors.

We are not really talking about different types of fuel nor are we attempting to make a list of it. There is another topic for that under the fuel consumption topic. Now that RON91 is no longer available (if I wasn't mistaken, it was 92 back then, not 91), we'd stick to the this rather old topic of RON 95/97.

We had RON 92 a while back. The rest of the world has RON 92. Just that RON 92 will complicate the subsidy. Price difference would only be a few cents and not much of a savings. Since our petrol is subsidised, there cannot be any competition in pricing unlike other countries with petrol kiosk selling RON 92 at much cheaper rate to attract customers. RON 92 would also hamper logistics.

Here's my take, use RON95 if you know it is fresh from the oven, but I don't know if this is available info. Most probably not.

I drive a conti TC car and recommended fuel is RON 95 but being a cheap ******* like I always am, i buy fuel on cheap days, cheap for a reason, assuming service station still has the old batch. Car engine management system will always detune with old RON95 batch but good I have ECU overide device so error codes not a problem.

Fact is where I am RON98 is the better fuel....no brainer. For now, I have a refuelling strategy, half tank for RON95 and RON98 for full tank.

Hope this helps.

You have that option in Australia.. cheap days.. cheap outskirt kiosk.. where they can price the fuel according to location and availability of stocks.. and of course oil price.

There's no such option here and to pump RON 97 just means that somebody else is enjoying our subsidy.

mean we cannot use the cheapest fuel and the more expensive fuel .. as the cheap 1 no good for our country economy? and the expensive 1 just waste of money .. if that so .. the fuel industry R & D should close their office and continue to use ron95 till the end ?

rural areas are actually dearer due to logistic issues...but yes very hard to troubleshoot problems like this. Best to run higher octane fuel for performance cars as much as you can.

RON95 on normal cars is not a problem except for Shell that you may experience a small drop in performance.

Yes but that has nothing to do with R&D (you terpesong to R&D). It's all economics. Fuel stations will have to build additional holding tanks. Tankers will have to transport more fuel types. Not worth the few cents of savings to the public. Even now, stations serving RON97 is beginning to disappear but I'm sure they have some form of 'agreement' (gun to their head) with the gov that each brand must have XX amount of RON 97.

Therefore, it is not viable to provide RON92 in a subsidised market. Nothing to do with R&D.

I've read somewhere before, probably on Paultan but can't find the article, it said that our fuel stations can have multiple type of fuel at the pumps without any problem or any additional investment. However there would still be some problem in term of keeping enough stock for the type of fuel that is most in demand.

Euro standard is indeed more for emission control but it also dictates a cleaner fuel requirement which will make your engine last longer and able to retain its power output better after a period of time.

I'm running RON 95 for 5 years after engine overhaul now. (Cracked piston) Lets just say that u need to do a few adjustments to milk everything out of RON95 fuel. But i'm running carburetor and i have the luxury of playing around with numbers like O2 machine and such. I believe all ECU can calibrate itself to make use of RON 95. Of course bigger RON number does let u make big HP. But i have always seen in USA those stock drag cars that use RON 91 can make 600hp and when use premium like RON 98 can make 700HP.

So comes to the part that those are high end drag engines. On our engines that usually make 100hp more or less, actually barely noticeable difference. Unless if we could have an engine room, fill one up with 97 and one with 95 and let them idle and see who finishes first. Then do an engine dyno. There will be difference here and there. So whose game?

Actually, he already addressed your query quite adequately. Short of physically telling you and addressing what you need to know in person, I don't think there's anything else he can do to answer you online if you don't get what he's saying.

Also, the moderator has never at any point stated anything regarding the car he has or what you have, nor has he talked down to you because of your financial status, that kind of thinking is entirely perceived by you and you alone. So just move on please.

for older car using cis-e injection, the ign timing would restore within seconds after knocking stopped.

This is what I meant before when I said the ECU will take a few steps back when knocking is detected and will take a step forward at a time after the knocking stops. Then when it detects the knocking again, it will repeat the same process. Just like sleepwalker said, if the engine is not designed to take advantage from high RON fuel, it won't be able to extract more performance from the higher RON fuel.

Can someone shut the conflicted people up and carry on with the discussion? Seeing all this mud slinging in every damn thread is getting goddamn tiring.

Unless if we could have an engine room, fill one up with 97 and one with 95 and let them idle and see who finishes first. Then do an engine dyno. There will be difference here and there. So whose game?
*
I don't know any workshop in KL that has an engine room. However if you're talking about dyno-ing the actual car itself on the differences in performance, I am game.

Caveat - both my cars take at least a day to adjust itself to the petrol for some reason. It's not immediate. So it'll be minimally a 2-day dyno effort.

just like the lady (vicky?) on Topgear said in her comparison on the different RON fuels, it does have a difference, although most average auntie/uncle wont notice it. the engine feels more responsive to the throttle press.

Did you check your fuel filter? Engine choking are usually the signs of a clogged fuel filter and by putting something like a fuel injector cleaner, you are actually not just cleaning the injectors, you are also cleaning some of the gunk collected on the fuel filter. I have seen this happen many times and the symptoms come back after a while unless the fuel filter is changed. Always use a fuel injector cleaner only after you have changed the fuel filter, otherwise the injector cleaner has to go though a dirty filter and end up cleaning the filter instead of the injectors.
Never thought of it, my car is maintained by the 3S centres, that's actually funny since it has clock over 90K and I don't think I've every signed on any fuel filter change.

Will check on the next service, but I do reckon that our quality of fuel actually causes carbon built up and such, it is recommended to clean the injectors.

Thanks anyway.

We are not really talking about different types of fuel nor are we attempting to make a list of it. There is another topic for that under the fuel consumption topic. Now that RON91 is no longer available (if I wasn't mistaken, it was 92 back then, not 91), we'd stick to the this rather old topic of RON 95/97.

100K km is a common fuel filter replacement schedule but some manufacturer's might change it early. At 90k km I can say its pretty much clogged up by then if it has not been changed before.

What bull crap is this?

Those people who says this are obviously lacking knowledge and are picking it out from the sky without any concrete backups.

Same to those who says 5w-30 / 10w-30 oils are meant for Kancil engines.

These are all old mindsets. Wake up!!!!!


Added on October 24, 2012, 4:55 pmMy family cars consists of Pajero, Benz, Civic and Wira have been using Ron92 for more than 10 yrs. Then migrate to Ron95 compulsory by government regulation and joining the pack are two Persona and Kelisa.

No issues at all. No power issues also because these cars are designed to run Ron92 and there is no point pumping in Ron97 because the engine won't perform anymore power than it is designed for.

so what EO does kancil take? what is the recommendation by perodua?

as far as petrol goes, stick with recommendation. if you cant pay ron97 when driving a car requiring it (eg: ferrari/lambo), you probably shouldn't have driven that car in the first place

On some cars the responsiveness is apparent. But on most normal 'standard' cars, it's not. Some cars meaning those higher than average compression setup cars but less than those high compression engine cars.

But like you said, in most cases it's negligible. Unless you've been driving the same car in exactly the same conditions (same car wear and tear, same roads, same potholes...) and suddenly you change the petrol and you say it feels different, then perhaps... it's placebo? A very strong placebo. Humans are not creatures of change and most of the time are unwilling to accept change until it's forced onto them.

Is it just me or when i try
Shell: i step on the pedal, engine respond delays like 1 - 1.5sec ,engine revs louder, speedometer rises slowly when i'm trying to go 100 to 120 km/h
Esso/petron: stepped on the pedal, engine respond time to the pedal 0.5 - 1sec , engine revs but not that loud compare to shell, and speedometer increase faster.

True?

i dont think its only you.

i dont even need to drive the car. i just start it in the morning with shell and the idling is so rough!
with BP or Esso the idling is smooth. happens every morning until i changed the fuel.

Ive been using Shell 95 for some time now. But recently changed to the new BHP RON 95 fuel. After 2 full tanks, i notice that my car engine sounds louder when idling. Not sure why. Anybody else tried the new BHP Euro 3 fuel?
