Funny how so many of y'all have problems with the gas gauge. The one in this Burb is pretty accurate. If it says it's half a tank down, it'll take ~22 gallons. I don't top it off; when the pump shuts off, I stop. Topped off the 06 too many times, trying to get as much in the thirsty beast as I can, and got the code for the evap solenoid. Got to crawl up there and replace it, and deal with the so called quick disconnect fitting.....learned my lesson. And I try to only get gas at one Shell that I've never had bad gas from.
Same here I think lol. Does your gauge dance or twitch constant? Lol
