#1. Fill Your Tank

Want to calculate the mileage on a car? The first thing to do is to fill the fuel tank. To do this, you need to use a pre-decided fuel pump and a specific dispenser to fill the car’s tank.

#5. Refill Again

As soon as your car is low on fuel, visit that same pump and refill again. Once more, do not refill the dispenser once it stops due to the auto cut-off. Take note of how much fuel was used.

#6. Determine the car’s mileage.

Calculate your car’s mileage by dividing the distance you traveled, as indicated by the trip meter, by the amount of fuel consumed. It isn’t something difficult; it’s quite simple.
