    was using 98 ron fuel and got about 350 km a tank now i switched to 95 ron fuel and looks like i can get 400km plus a tank.....how is that ? all this time thought the 98 ron was better.

    my car's only modification is a d sport drop in air filter . 660 motor

    Maybe using 95 slows you down a little ;)

    98RON is a higher octane so burns faster, doesn't it? You get higher performance (in some cars) but not as many miles to the gallon? I have to say I haven't noticed the difference between the two in my copen, but in my husband's 2.3 V5 beetle, the engine pings if he doesn't use the higher RON.

    I have to agree with the above my 1.3 Copen ran the same on both, I used 98 ron for 6 months. Not the slightest difference.

    Especially at the price I just stick with 95 ron.

    mileage per tank

    looks like I will get about 400km per tank on 95 ron fuel for my 660cc motor.

    Will it hurt the engine much with ron 95? I use ron 98 all the while..

    Oops...I've been pumping RON 92 into my Copen cos I read somewhere in the manual that min octane is 90...pls advice.

    I drive a 660cc Copen made in 2009.

    Correct, min RON 90 required, so no worries.

    Phew...thanks! I thought my engine was getting damaged without me knowing...you see, because my manual is in japanese and I just can't make sense of anything...if any of you have an owner's manual for the 660cc in english in softcopy...pls let me know.

    Just incase you hadn't realised....
    The service manual on the 'Directory' tab of this site is for the 660.
    But the owners manual is for th 1300.

    Hi Rex, am aware. That is why I was asking if anyone has an english manual for the 660cc Copen to spare. Because in the service manual, the technical data doesn't specify octane requirements etc.

    Ive only ever used the 98, and if you want your engine to last the longest, use that only. economy adjustment is minimal. I had the good fortune to speak to a engine designer for Daihatsu. Described as "clean burning" it benefits your engine in the long run, and you dont get those "pings" that sometimes come if you use the lower ron petrol

    I've started to use Esso 95, not the supermarket stuff. I've found the mpg has increased slightly, but it could be other factors. There are a lot of debates, of whether the supermarket brand is the same as the well known ones. I'm not sure - whats your view?
