I know the manual says to use 87 octane. But, will power or smoothness increase with higher octane? I suspect the answer is no and 99% of you use 87 octane.
Some vehicles will carbon up. My brother had an oxygen sensor malfunction on a car. Dealer said he had his one chance and future problems would not be covered by the warranty.Will it hurt to use 93 octane? I've been using it because I forgot the manual said to use 87. I did read the manual!
I believe that your country uses a different measuring systemdown here there is no 87, the lower one you can get is 93 and i use 95.
