Our cars are supposed to have 17 gallon fuel tanks. My fuel gauge read a little over a quarter of a tank of fuel left, but yet I just filled the tank with over 15 gallons. A few years ago, my car ran out of fuel because the gauge was reading about an eighth of a tank left. Luckily my car died while going down hill on the highway and I was able to coast down an exit ramp and into a fueling station. Does anyone else have an inaccurate fuel gauge?
