My fuel gauge keeps going up and down. For example I will fuel up it would be ok full and then I drive for a while goes down says need fuel and the back up after a while. Any ideas what it can be?
Yes I mean a short while and some days I think the problem is gone cuz I will drive a day with no issue but then the next day it will happen again the gauge will go all the way to empty.
Hi. I know that some time ago Shell gas was coating / gumming up floats in gas tank and causing problems in GM vehicles. That was a few years back but if yours is a 2007 it may of gotten some of that gas back then and along with a bit of age may be showing effects. Try the dealer, they are aware of the past problem and I believe had a cleaner for the tank that they suggested. Never know might work, inexpensive and easy to try. Good luck.My fuel gauge keeps going up and down. For example I will fuel up it would be ok full and then I drive for a while goes down says need fuel and the back up after a while.

I use nothing but Shell premium which is supposed to have no ethanol. I've heard of other brands causing problems but who knows. Zero problems with Shell gas so far, with over 80K km on the odometer, knock on wood and the car is a 2005. The electronics on these cars are my biggest worry and can be expensive to repair, as mentioned above.
Thank you I will try it out.Hi. I know that some time ago Shell gas was coating / gumming up floats in gas tank and causing problems in GM vehicles.

Thank you Riley I appreciate your reply I will try sea foam see what happens.My 2000 does (or did) that, once I hit 1/3 of a tank, the needle would drop off the face of the earth. With about 1/8 of a tank left, it would come back to let me know I'm about to run out of fuel. One explanation was a gummed up rheostat, where the sensor would hit a dead zone. I used a couple of bottles of Sea Foam over a couple of tanks and the problem has mostly been gone. Others state that the sulfur in the fuel corrodes the sending unit so it can't be restored, so maybe I am lucky with there being a bit of a film. In my old workplace we cleaned our circuit boards by soaking them in toluene, which is also an octane boost! We had 5 gallon pails of the stuff, but I moved to another job before I could test it out, however, I bet that would clean any film off the sensors. And, if you were to do this option, do some research first to make sure you're comfortable with it.
