must check this out. but in my understanding MOST cars except those with very high compression rates and meant for racing can use Ron91 and above.

Just check Singapore. They have Ron 92, 95 and 98 on sale. And most of their cars are the latest in the market.

in Thailand, Unleaded Premium is Ron95 and it is expensive like hell.  Gasohol is Ron95. and they have Ron91. Car rental company in Phuket recommended I pump Ron91 only for the Vios I rented last 2 years ago when I was in Phuket.

In America there is stil Ron88 or 89..forgot liao....

My honest opinion, Malaysian drivers have been cheated to use high Ron for nothing.... only because korupland gomen want to increase price they phase out Ron92 and come out with Ron95 with of course immediate price increase! Then feed us with propoganda that Ron97 is premium so all of us pay ridiculous prices for our expensive petrols.

It is not really ~ as u can see nowadays our car's compression ratio was set above 8.0:1 hence minimum acceptable rate for RON is 95 with AKI 90 minutes ~ ... or else have to add variable valve timing, knock sensors to delay ignition timing to protect our engine ~

and It is possible to manufacture gasoline engines with compression ratios of over 11:1 that can use 87 (MON + RON)/2 (octane rating) fuel with the addition of variable valve timing and knock sensors to delay ignition timing. Such engines may not produce their full rated power using 87 octane gasoline under all circumstances, due to the delayed ignition timing.

So that is why i said higher RON is better especially for stock engine ~

Hi Bro...
Campro 1.3L has compression ratio of 10:1 

Probly dat's why by using RON 97 or a mix of 95/97 gives a smoother (?) & quieter (?) engine...? 

So if Govt changes 95 to 91, a similar mix wld help our stock Campro...? 

ps. Since 97 price drop, me hv started mix of roughly 3 parts 95 with 1 part 97...
Any Bro has tried similar mixes?
Pls share...TQ!! 

above old town got korean restorant

If Puchong Asia Cafe, I can drag my car out. If Sri Petaling, I think it's too far to drive with damaged drive train.
