My GMC Sonoma seems to be getting way less mpg than it should be, its supposed to be getting 14-16 city but it seems I’m getting less than ten. I just got my gas tank repaired due to a leak and they did somewhat of a once over in order for it to pass inspection, but i don’t know why its getting about 8 mpg. please help ---

an additional question to the problem, could it be a faulty fuel gauge, or sensor ---

What year Sonoma, engine, and transmission do you have? Is it 4WD or 2WD, and what is the rear end ratio? ---

And how are you measuring the mileage? Have you ever gotten something close to that 14 - 16 mpg? It could have a lot to do with the load, gearing and your driving style.
