My gas meter has been very inaccurate and unstable. At times it would go down significantly, as though I'm burning up fual THAT fast. THen the next time I drive, the the needle would actually go back up, as if I'm getting gas as I go. My mechanic has no idea what could cause that. Does anyone know?

 

Your fuel level card on the sending unit probably has sulfur build up on it. Try using techron fuel system cleaner in the gas and drive it. If that dosent work you'll need a new sending unit/fuel pump assembly.

 

hey i kind of have that same problem. its weird, sometimes ull go through a quater tank so fast and other times its like normal. and of course its premium fuel too.

 

Pretty much all gas gauges will move slowly when around full, then suddenly dive.
