I had been under the belief tha the higher the octane gas you're using, the better the gas mileage???

Ha i buy allot of cars from them, this year we pretty much got all new rides in the fam. My girl traded her o6 gli for the 08 R32, My sister got a new scion, mom got a new 4 runner, and I have a new tacoma, Just sold my 07 srt8 superbee, and now a challenger on order. Plus my sales man also happens to be a good friend of mine. It helps hehehe.
As for fuel to run in these cars, my srt8 superbee charger was run on 93 and it helped. I wont run regular gas in any of my cars actualy. 93 does help it out even though you lose a little mpg. The engine does not ping and carbon deposits are at a minimum. For those times when you mash the gas it is a big difference.
