Can I mix 91 octane with 100?
I have a 05 Evo flashed for 93 octane, the gas station i get my 93 from swiched to 91, but they also sell 100 octane race fuel. What i'm asking is if it would be safe to mix a little 100 with 91 to make up for the difference? Or should i just get my car reflashed for 91.
