they will never bother to watch and read. coz it is edi in their knowledge.
It is just like explaining the new technology difference of last time car to nowadays car to my dad.
well, at least my dad read and understand.

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.

im surprised no one has related protons power window failure to the quality of oil....

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. Everybody who had no choice must resort to Ron95, the cheapo petrol at the moment...

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.

wait for RON2013 la, car no need service already, even abs kong also it will heal it self, cause it is RON2013

this thread has made my day.. LOL.. RON2012 and RON2013.. HAHAHHAHAHAHAHHAHA

sarcasm level :- forum.lowyat.net/TheFast&TheFurious

RON95 burn your car easily...RON97 burn you money hardly? LOL

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.

My dads Mitsubishi has been pumping ron95 for 32 years. Doesn't seem to have any problem also.

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.

Added on August 2, 2012, 5:58 amWho 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.

This is not the worst I have heard about RON95, I've heard more hilarious comments like "RON95 make your engine consume engine oil and then damage the whole engine where you need to overhaul it".

RON95 killed my rabbit

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.

***Luckily, nobody here proclaiming "I pump minyak kelapa sawit my car still running like a boss**

minyak kelapa sawit also got. its biodiesel.

minyak masak yg terpakai pun boleh pakai. but this is usually for diesel cars lah...

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...

their mindset. in penang, already 2 cases myvi burnttttt...
anyone here is the owner of those myvi..? myvi , ppl will blame ron95.. because they said is myvi is toyota quality but i disagree because myvi dont even have 30% of toyota quality also..

this is a good suggestion...used to do that ages before... will try it again with my current ride (vios).. now using RON95 exclusively... but on my Wira (11 years old car).. still using RON95 but from different station.. most of the time will be Caltex... so far so good

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


= 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!!!

Where does the conclusion comes from?
