What do you guys usually get to a 1/4 tank in your GT's? In my 00 GT I get around 150 miles. That's using 3/4 tank of gas. I don't really ever do any highway and its mostly just city driving to and from school and to friends house and wherever. I don't usually get on the freeway much unless I'm going to the beach or something. But I average around 14.5 mpg. The best I ever got which was with highway driving was 17mpg and the worst was 13.8mpg. I do get on it every once in a while though each tank of gas. I just can't help that . But I also drove like a grandma once and that's when I got 13.8. So I'm just wondering what kind of driving techniques you guys use or if I need a new fuel filter or something.
