    So I just filled up my tank yesterday, and today, after about 35 miles, I noticed my gas was fluctuating.

    It was starting to steadily go down to about 1/2 tank, and slowly (much slower) go back up, and only to about 3/4 tank. WTF is going on?

    This is a 03 extra cab. 2.4 MT. It has 162k miles on it.

    I have no idea what's happening here. Anybody knows or have any ideas?

    Thanks!

    Were you going uplill or downhill enough to shift the float in the gas tank? It has been my experience on other cars that when this happens the gas gauge reading wil drop quickly but rise back up to normal very slowly.

    Also, sharp, long turns can also throw off your gauge. Anything with any sort of angle or g-forces will move the fuel around. It could also just be that the imperfections in the road caused just the perfect amount of movement in the tank for there to become waves over time, which would cause the float to drop down a good amount.

    Make sure to watch your miles and that your gauge does actually keep the right levels, as it very well could be the float is stuck or the sensor is malfunctioning. It's just one of those things that can happen with age. Only way to know if that is the case is to drive it and see if the level actually moves. Just dont run yourself out of gas.

    I wouldnt worry about this at all every vehicle I have driven does this its probally you just never took notice to it. How often do you actually really look at your fuel gauge when driving. Sometimes I look at it and I can see the it quivering and moving a bit. Id just keep an eye on it. Now if it goes from like full to E then back again I might get it checked out haha good luck

    Thanks for the reassurance, everyone. It was just such a drastic drop that concerned me a bit.

    I'll keep a close watch on it.

    Thanks!
