The gas guage on my T/A has always been a little "Goofy'. After I fill it up, it sits on the high peg for what seems like a week, and then it slowly starts to come down towards half-tank. Once it gets to Half-tank, it seems like it falls off 5 times faster! It is just a bit "non-linear" to say the least. By 1/4 tank, I start looking for a gas station. Anyone else have this, or does my car just suck?

 

yup mine does that, also if its under a 1/4 and I just sit there in park I can see the needle drop...but at full tank it chills for a while...classic...a solution would be great also

 

it's the "V" design of the tank. nothing you can do about it

 

happens on my other car too... and theres really no way the manufacturere can fix it either..

 

yea, its a joke, i go by the trip odometer. mine doesnt even go up at all half the time even when i have half a tank

 

honestly my car doesnt do this. it's usually pretty accurate.

fwiw my window motors havent gone out yet either, 100k miles

*knock on wood*

 

Yep happenes with me. Expecially if I'm doin city driving.

 

this is the answer.

/thread

 

oh yeah mines totally jacked as of late. When i first got it (@ 126k miles) it worked perfectly but now (134k miles) it drifts a lot.. acts like its going down to fast and its intermittent.

 

yeah mine does the same..when its at a quarter i know i cant go too much further cuz ill be on empty soon, and when i put it in neutral the needle moves down about a quarter tank?

 

Mine stays up towards F a little longer than the rest of the time but is fairly accurate otherwise. When it reads 1/4 tank it is pretty close, not exact but I never expect it to be. Ran it down to close to E once and I still had about a gallon and a half left. Not too bad, much better than my old car that would run past E before I was even at a quarter tank

 

Both of my fbodies did that I just fill them up at 200 city miles when it says around a quarter tank...I know it goes empty from there learned that the hard way one day home from work lol

 

Same here....

 

my 02 doesnt gauge is actaully pretty good

and my old 95 and 97 did that

 

yup, the fuel depletes at an exponential rate

 

LT1s seems to do it the worst. I go by the od. for the most part. Mine goes way above full and once it gets down to the F its really about half and at the 3/4 its more like 1/3. Once it gets down to the 1/4 its got maybe 2-3 Gallons left

 

yup once mine gets to about half the gauge plummets...

 

When I first got my car my gas gauge would oscillate up and down a little bit like it was hunting and then stabilize, but it has not done that in years now.

 

how the hell does the "V" design make any sense, common sense says to place the sensor higher than half of the tank (top of the v) to compensate for the inward point at the bottom. i do know it is shaped like a v, but wouldn't that be the smart place to put the sensor instead of the direct middle?

 

it doesn't matter where the sensor is. What we meant by the v-shape making a difference is because the percent that the fuel tank empties out, which is what the guage does accurately represent, increases exponentially as the tank empties out
