My gas gauge goes nuts sometimes after some hard acceleration. Its keeps thinking im driving at full throttle everywhere and the dots just tick down every 5 miles or so. Then I get gas and find out I had like half a tank left. Its really really annoying.

Mine didn't start doing that until after 8K miles!

Every time I get a new car, within the first week, I carry a 2 gallon plastic gas container and run out of fuel on purpose just to see what the gauge indicates and how the car acts when it runs out of fuel. I also fill the tank to the limit every time I refuel and set the trip meter.....and figure my mileage on every tank so I will know where the gauge is when it runs out.....this way you should know how many miles you have left before you run out......comes in very handy when you are traveling and between exits on the interstate. I have found out that most gauges are what I call "Top Loaded". By that I mean the top half tank will give you 200 miles and the bottom half will give only 160 miles.

this is fuel starvation, not a running out of gas situation. In hard right turns, the fuel must slosh or something and doesn't get into the pickup. I've been towed off the track before not knowing what happened, and I'm fairly sure that had I just shut the car off and restarted it, the fuel gauge would have reset to half tank, where it really was.

btw, exiting the carousel at Road America at 5500 rpm in 4th gear, it is happening to me occassionally with 1 dot not lit (basically full tank!), and always with 2 not lit. major PITA!

Spearfish rode with me today and got to experience it in my car as a passenger. It can be scary at 100mph with someone right on your bumper and you unexpectedly slow instead of accelerate!

:iagree:

If you fill up when the warning shows, you can get a good idea.

Any fix to this? i have like 2,300 miles on mine, went to fill it up to winterize it and of course the last LED isnt lighting up. I thought maybe i didnt fill it all the way, went back and pumped more and poured gas on the car. I am not a happy camper....

Running yourself out of gas on purpose or not is not a good idea. The fuel also cools/lubricates the fuel pump. If it overheats.....BOOM!!!! No, just kidding. But you could do damage to your fuel pump.

What he said. If you look under the car the gas tank is shaped like an upside-down U with the driveshaft running through the middle. The problem with this set up is that the pick up is only on one side of the U. This makes it very easy for all the gas to transfer to the side of the U without the pickup and cause fuel starvation.

Maybe it needs a pipe connecting the two halves?

I have been doing this for more than 40 years .....on about 10 cars....never have I ever had any problem.......
