During these past few fill-ups, I've noticed that the needle doesn't go all the to the F line. Instead it's below it. A long time ago, I remember that the needle even went past above the F line. I tried everything.. different gas stations (sunoco, exxon, etc.) and even tried to see if topping off would help. Is there something wrong with it?

 

no idea what the heck that is because mine started doing that also about 3-4 months ago after i filled up after being at the track. i thought the pump just stopped early so i went back later and put in .20 lol. from then on it never goes where it used to go and i have no idea why that is??? it makes me mad somtimes though -Ryan ...maybe its a 99 thing?

 

This isn't really an answer, but I was over at How Stuff Works, and there's an article the about How Fuel Gauges work, which might be of interest.

Another cool article talks about finding the best speed for maximum fuel efficiency. I didn't realize that driving at say 30 mph is actually less fuel efficient than driving at 40 mph. Check it out here.

 

I could be wrong guys but it might be full but the needle might have moved a little?

 

well when i know for sure that mine is completly full my gauge reads it to be almost 1/8 tank down already though it doesnt move off that for about 120 miles which is correct, its just wierd -ryan

 

Mine did that for like 1.5 years when I bought it used. I always filled up Shell here in Canada.

I then now moved only to Petro Canada and after two fill ups 1.5 years ago, I always read full. It was a gas thing for me for sure based on my fill ups here and there with shell. It is really weird. BTW, I only fill up regular.

Car still runs great and dont tell me my car is going to explode by using regular. I belive 99% of the non .org owners fill up regular. I know guys who own 95 max's and after 9 years, creeping on to 10 years, no problems what so ever.
