It's a good thing that the gauge shows "E" before you are actually empty! I had a car several years ago that was the opposite; it would run out of gas when the needle was on 1/8 tank..... NOT GOOD!i filled my tank up from "E" and it took 16.5 gallons. the tank is supposed to be 19 gallons. i take it this car has a reserve tank of about 2.5-3 gallons? im making sure before i take my long road trip to vegas!
