For my car = underpower and doesn't save much because I will need to press more on the accelerator

Some people complained knocking for their cars also....which I find it weird too

My old e46 also states that it can use "Unleaded RON91-98" while SGTI "says" min RON95

For those of you that say RON95 is JUNK and worship RON97!!!

Unless you driving performance car like GOLF and SUBARU then yeah it make sense

Normal car... better give me your money...

i gained more mileage with Esso RON95....

RON95 i would prefer bhp or caltex
they are more reliable in my opinion
97 will go for shell or bhp

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.

not true ... can taruk 95 if needed

Dear TS.. your car going to KONG soon. not becos of the fuel RON u used all these while.
who is the hell of your mechanic cerita grandmother story to u? all wrong/false claimed.
my advice to TS, pls get another workshop to get your car repaired.

merc E class n bmw recommended fuel is RON95, Min is RON91.
but i heard proton wira having problem using ron95, so many ppl in the market says RON95 cannot use and will spoilt engine after sometime, maybe they are those ppl driving wira and maybe is rumours.
what say u

Anyway enough talking...damages caused to the car is NOT due to the fuel. Case close

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)..

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..

You guys honestly believe this dude's scuderia caught on fire due to him using ron95?
OR even more relevantly, you guys believe a ferrari owner filled him tank with anything besides 97?

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.

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.

got money, buy RON97

no money, buy ROn95

not enough money, WALK.

After using Ron 95 for the third tank. I realized that my car engine bay is hotter. I never felt so hot before when I was using Ron 97. Anyone Can confirm this?

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

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