🚗 Car Mileage Calculator
Calculate your vehicle's true MPG and figure out exactly how much your trip cost.
How to track your true MPG
Your dashboard computer is often slightly inaccurate. To calculate your true Miles Per Gallon (MPG):
- Fill up your gas tank until the pump clicks off, and reset your trip odometer to zero.
- Drive normally until you need gas again.
- Fill up your tank until it clicks off again. Record the Distance Driven on your trip odometer, and the Fuel Consumed (gallons) from the gas pump receipt.
- Divide the distance by the gallons to get your true MPG!
