Super Six fuel mileage

lol you guys are crackin me up! i have the push button 3 speed. HYPERMILING! THATS THE WORD I WAS LOOKING FOR! lol yes, this is helping. this post was just more of an inquiry, but it is definitly a learning experience.

I dont get run over, but after 50 the fuel gauge begins to move faster than the car. Even with the smaller tires.

Is the tires you have on now bigger or smaller than your old ones?
