I've found that 76 gas seems to give my Neon better mileage than any other brand. It might have something to do with the fact that 76 is the only brand out here right now without MTBE.
I might need to try 89 octane to see if it helps mileage any.
well, it might help the mileage per tank, but you also spend more money filling the tank, is all a matter of doing some number and see if the extra cost of the gas is cheaper for you.
