Hi, my fren has a Mini Cooper S, and he would like to know whether RON 95 is suitable for Mini Cooper S or not?

yes.
suitable

bcos i heard that RON 95 is not good for the car engine as its lower quality than RON 97..
its suitable but not good for engine ?

engine can even cope with ron 92

go and ask bmw..............but i think almost all engine can handle anything better then ron91,but then im not so sure coz im using diesel

"S" brand at all the while... now he pumping V-Super, haven't try RON 95 yet..

Never heard of the owner's manual? Go read it.

if using super V then he will have performance shock when he switch.

the difference is too great to go from V to 95.

wean it off by mixing V and 97 first then gradually dilute to 95

otherwise your fren might blame you.

Good quote for the day
Read the manual spoon-fed...

so far as i know those turbo or high compressed engine no suitable to use RON95...
example our mod sleepwalker Subaru no able to compatible with RON97 very well, must be V-power...
but some of shell station no longer selling V-Power now, wondering what will happen on his car...

The MINI ECU should be able to auto adjust to the RON typre you use. It can range from 95 to 98.
My GTi has no problemo.

cooper s use forced induction..usually forced induction engine can use lower ron fuel..due to low engine compression unlike suzuki swift where the min ron is 98.

uikk swift cannot run 95 meh??or the ECU can auto adjust to lower RON like most car??

eh i mean swift sport. this is what i read from most swift sport review in mag n newspaper. even if the ecu can adjust..it still must be above the minimum octane number.

this is untrue. remember that compressed air has a higher density, and running that air through the turbo heats it up slightly.

so rich to have mini cooper S .. pump back ron97 ma...

hehe tq...but heard about the 1.3 swift manual and mazda2 were coming...*wahhhh*

Some of us have problems. RON 95 activated Check Engine light. Any power loss from switching so far? I'm sticking with 97
