I filled my tank on Sunday and the needle was past full. I've since driven about 65 miles in the city and it moved a little past F yesterday, but it's back in its original spot after the fillup (to the right of F).

I took a trip last weekend, but it was with my windows up and AC on. I got about 115 miles into the trip and the needle was barely to the left of F, which seemed a little too good. Could having the windows up make that much of a difference in fuel mileage, even with the AC on?

When I returned, I left with the needle in between F and 3/4 tank. Midway through my trip, it seemed that my needle started dropping like a fly. On that tank which was about 70% highway and 30% city, I got 22.xxx MPG, which seems about right.

My question is have any of you experienced any fluctuations with your fuel gauge like I have?

 

few days ago i went to the gas station with the needle way PAST "E" and i only put 14 gallons in

so they're nowhere near accurate ...

 

The gauge has always been fine until this happened. It's still reading full with about 90 miles on the tank now.

I always reset my trip odometer to calculate mileage, so I know when it's due for a fill-up based on that, but for those who don't do that and can't figure out why the car is "still full of gas", they're gonna run out of fuel.

I believe the gas gauge is underrated so you won't run out of gas. When it's close to E, most people believe the car's running on fumes, but there's really like 2 gallons left.

Either way, here's something else to fix.

 

in my experience its got like 3 - 4 gallons left by the time it hits E.

 

mine stays overfull for a while, drops like a rock when it crosses full mark and runs out of gas at 1/4 tank. so i dont run it below half now.
