I got a stock vq30de-k (5th gen) max. Would running unleaded race fuel hurt anythin on my car?

 

help? anybody?

 

No it will not hurt anything. I will probably not help you any though unless you are experiencing detonation.

 

Depends how high of an octane you will be running. Cause if its too high you can loose some power.

 

race fuel is for high compression engines where detonation is a major concern. you really dont need it unless you're getting engine knock, which shouldnt happen w/91 or better octane. i get nothin even when i use 87 (not a the strip of course, just daily driving). So no, race fuel wont make you go faster, it'll just cost more.

 

cool thanks guys.
