Yesterday I filled up about $45.00 of gas, and the tank was full right to the top. The fuel gauge is way above the F mark. I have driven the car for about 70 Kms., and the gauge has not come down. Will it ever come down? How many Kms. can the car go on a full tank (2.8 automatic) ? any suggestions will be greatly appreciated.

Yes, it will come down eventually and it won't stop :lol: Not sure about the auto, but my stock manual would get around 400km's per tank between city & hwy driving. I'd get 500km's on straight hwy runs.

Guess that's the difference between the 5spd and 4spd. I could only muster just over 400 strick highway driving - slow/steady.
The tank size changed in 87, right? That would also account for my differences.

If you drive heavy/quick acceleration plan on 300-350 per tank... unless you really tromp on it, then maybe 150/tank.

Ya I get about 300-350/tank in my 86 4spd. I consider my 1/4 tank mark the empty light - get to the next station I see lol.

your gauge might also be off/uncalibrated; they tend to drift at the resistor/sender in the tank over time..

caution:
if it reads way over full on full tank fill, it likely will read just above the empty line when (not even) close to empty.
ask me how i know :roll:

i think there was an archived pff thread on how to recal/clean up the resistor...
