What are “miles per gallon” and how do I calculate it?
The term “miles per gallon” or MPG is a measurement of how many miles your vehicle traveled for each gallon of gasoline used. To determine miles per gallon, fill the fuel tank of your car to the top and write down the miles shown on the odometer. Drive your car as you normally would until you have run the fuel tank down and you need to fill up again. Fill the fuel tank to the top and write down the miles on the odometer. Subtract the previous miles from the current mile reading and that will give you the miles driven from the last fill up. Then divide the miles driven by the number of gallons you just purchased and that resulting number equals the miles per gallon that you got since your last fill up. For example, if you drove 250 miles since your last fill up and it took 9.6 gallons to top off the tank, then 250 miles/9.6 gallons = 26.04 miles per gallon. It is important to keep track of your miles per gallon over time and calculate an average since your tank may be filled fuller at o
