Gas Mileage Question...AGAIN

baller760 said:

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.

I want to kick you all in the teeth.

You can't accuratly calculate MPG going by how many miles you have gone and where your gas guage is point to. The ONLY way to accuratly find MPG is divide the miles traveled by the EXACT number of gallons you used.

You can't just say...hmmm, I went 150 miles and my gas guage is pointing at 1/2 tank mark. That must mean I've used exactly 1/2 my tank, which is approx 7.5 gallons. So..I must have gotten 20mpg.

We all know that the gas gauge isn't accurate. For example, when my gauge points at 3/4 tank, I've usually gone approx 100 miles. Does that mean I'll be able to go 400 miles on the whole tank? No, because the gauge isn't accurate. I generally can go 100 miles on first 1/4, another 100 by 1/2 and then the 2nd 1/2 is another 40-70 miles.

ok...I'm done.

BTW...I average 19mpg (50% city/50% highway). Best mileage I've ever gotten was a highway trip...26mpg. Worst was my last fuel up after getting headers, Accufab plenum/tb and having my foot on the floor most of the time....16 mpg.
