So I notice my fuel gauge on my 06 STS v fluctuates about quarter tank or so when I'm under half a tank. Any one know why or how to fix easily? Will fuel system cleaner fix this?

Fuel system cleaner could "fix" the problem. When was the last time you put any in the car? If it's been awhile, it's time.

BG 44K is the one I recommend.

I've had issues with fuel gauges in my Vettes in the past and a good cleaner appeared to clear the issue.

The previous owner probably didn't either. Using a cleaner would be the first thing to do then.

I doubt she did, it was an old lady from Naples, FL

Bg 44k seemed to work alittle bit but most likely will have to have the part exchanged in the future
