On my 1993 civic Si my gauge seems to work fine, fill it up and it goes to F and gradually goes down to E like normal, or so i would think. The problem comes in when i fill it up off of E with the gas needle all the way on E. The most gas i've EVER put in the car is 8.1 gallons at 1 time, but it averages about 7.5 gallons, and i fill it up EVERYTIME. Shouldnt I put more than that in to fill it from dead E to fuel shooting out the filler neck.

 

Civic gas gauges are not very accurate.

that and dont keep filling after the pump stops on its own.

 

i wish that was the case, but these busted gas stations around here the pumps dont stop on their own. Well my freinds 00 hx fills up normally takes about 10 gallons like one would expect but mine has a false bottom or somethin. Can a bad fuel gauge sensor cause this problem?

 

bump for input on possible bad sensor causing the problem.

 

mine had a problem when there was a dent in the gas tank.

 

i was thinking that as well but there's no dent, but it would make perfect sense

 

I wouldn't bother with it. If it read too high instead, then I'd have to fix it.

 

well i'm trying to improve my gas milage and not fill up as often but its hard to do when i dont know when the tank is really empty. And driving till it runs out with a can of gas in the car isnt what i'm trying to do, just want things to work correctly.
