You can run all the way up to race fuel!.. But on a stock motor it's not going to do you any good!.. Won't hurt it any either!..

yes, but your car won't know the difference unless it is tuned for it.

it'll probably run the same as 93 octane, but you'll have a lower chance of blowing up your engine, if you're running FI
