you can use any grade of gas, but the premium has additives in it to make you car run better. Although if you know your not gonna race or floor it you could you regular and everything would be fine.

you should use premium, but if you dont the computer will retard timing so it doesnt really matter then except loss of power... but the place you get gas is important, and never get 7-11 gas...

Just use 91 octane or better. Your car will run fine on 87 as long as you dont stomp on it. Anything over 93 octane is a waste of money, as the computer could care less if its over 93 octane.

If I was doing a long distance trip over a couple of days with no plans to get on it, I would use 87.
For tooling around town and just having some fun, 94 is what I use.

Don't forget the fact that you will usually get a little better mileage with better fuel becuase the PCM can advance the ignition more and produce more power with less throttle input. Helps offset the price of the premium fuel a little.
