I thought a higher octane really just meant the fuel was (for lack of better words) cleaned more. Less little particles and such floating around.
With my other cars, I got better gas miles running the cheap stuff than I did the more expensive. But I don't have the gutts to try running the cheap stuff in my car. I really don't want to blow the car up.
Thanks all. Still funny to see people complaing about $2.60 a gallon. Right now I'll take it!
