i dont under how u guys get get more that 300 mpg to a tank. Since my i first bought my car brand new i only acheived that couple times by going on a road trip. Right now i have half a tank of gas left and the tirpodometer is reading 122 miles. so i get 122 miles to half a tank. for this tank, i havent ran the a/c nor have i punched the gas. A buddy of mine told me that the gasoline in this area was oxidized, but i dono what that could do.
