"I fill my tank up until it will take no more. As a result I have very accurate fuel mileage history"........ I've always been told this a bad thing to do. I used to do it all the time and a friend of mine's husband said I shouldn't do it cuz it will cause problems.
Going off-topic a bit, but I have a question..... I've noticed when my gas hand get to the 1/4 mark it will start "floating" so to speak when accelerating. Is this normal? Should I have it looked at? I might have a quarter tank, but the gas hand will move up to almost 3/4's.
