## How do you calculate fuel economy?

**Calculate**

- Get the miles traveled from the trip odometer, or subtract the original odometer reading from the new one.
- Divide the miles traveled by the amount of gallons it took to refill the tank. The result will be your car’s average miles per gallon yield for that driving period.
