my mark doesnt display the correct gas reading on the display and the fuel gauge reads gas a quarter tank too full.it seems to fairly calibrate once the tank gets to about a quarter. I notice when i turn the car off the gauge sometimes rises. when i fill the tank it points far above the max mark.
and the digital readout takes miles of driving before it too can calibrate.
 
Mine is opposite, reads low after filling. I have noticed that the car must be level for a semi-accurate reading. The other day I drove 15 miles after empty on the computer, Not fun!
 
Do you guys turn off the key when you are fueling? I've noticed that most all FoMoCo cars/trucks require that the key be off for accuracy.

yes key is not in the ignition.
i just bought this car last week and the owner also knew about it.
 
Maybe HE kept car running to fill it...or listened to radio....try a couple of complete fillups and see if that helps....usually it does.
 
I second that.....especially if its a 97/98. Our patrol cars will do that same crap if you leave the key on, but only on the 03's and up.
