gas tank/gauge problems

**Ripper415** · 07-01-2006, 12:08 PM

I wasnt sure where to post this topic but I figured this was as good a place as any. Basically when I'm driving around in my 02 SS it seems as if the gas gauge barely moves. But the next time I start the car the gauge goes down like an 8th of a tank. It's really pissing me off. For example, I'll drive to work (about 10 miles of highway cruising) and the needle will go down like 1 milimeter. Then I'll get out of work and turn the car on and the new reading on the gauge will be like a centimeter lower?! It cant be a gas leak because I'd definately smell it or see liquid spots under the car, and I dont. Also, another thing I noticed is that it seems to take a lot longer for the tank to get from full to half then it does to get from half to empty. I just got this car a few months ago and was wondering if anyone else had these problems too, or if theres some kinda defect with just my car.

Sounds normal to me. My driveway is on an incline and it always reads higher pulling out - go to the store 8 miles away - restart and it's considerably lower. And yeah, it'll take a lot longer going from full to half, than from half to empty. Usually a bad sending unit will read full forever, then drop like a rock (if it does at all). Be nice to your fuel pump and don't let it fall below 1/4 - seen to many "ran low/out of gas and now my fuel pump won't work" posts.

Because of the shape of the tank (for the T-tops) 5/8 is actually 1/2 a tank on the f-bodies. I know for a fact it's been that way since '93.

haha so if 5/8 is really 4/8, then when it says 1/8 i must be down to my last few drops of gas lol. good to know that particular problem isn't out of the ordinary. but what about the thing where i'll turn off my car, then the next time i turn it on the tank needle has moved down like a centimeter? assuming theres no leaks, shouldnt the amount of gas in the tank stay the same?
