Miles Per Tank Calculator

-miles on a full tank
-safe range with reserve

Work out how far your car can travel on a single tank of fuel from its tank capacity and its miles per gallon. Enter your tank size in gallons and your real world MPG, and this calculator gives the full theoretical range along with a safer range that keeps a reserve in the tank. Running down to empty risks leaving you stranded and can shorten the life of the fuel pump, so a reserve of one or two gallons is a smart cushion. Knowing your range helps you plan fuel stops on long drives, especially in remote areas where stations are far apart. Enter your tank in liters instead if you switch the units. Everything is calculated in your browser, so your car details never leave your device.
