How does this work? How do you accurately calculate the mileage?

I FILL my tank to the very top - drive for a couple hundred miles, then fill it to the very top again. Then I do the calculations (miles traveled divided by the gallons just added).

If you are only adding 10 gallons each time, how do you know how much gas you used?

Take Care,
