That all depends on your compression.

93 octane will do you just fine... if you go any higher you will be jsut wasting money, it will hurt more than help

It's depends on what altitude he is at. If he is at or below sea level, he may have too high of compression to run 92 octane.

I would say you are in the grey area. Close to pump gas.

if you want to feel safe mix some 100 and some 93 for a 50/50 for a oct of 96.5 ir if its 91 oct it would be 95.5 oct
