A »To calculate fuel economy, fill your tank completely and reset the trip odometer. Drive until it's time to refuel, then note the miles driven and gallons needed to refill. Divide the miles by the gallons to get miles per gallon (MPG). For example, if you drove 300 miles and used 10 gallons, your fuel economy is 30 MPG. This provides an effective measure of a vehicle's efficiency.

A »To calculate fuel economy, divide the total distance traveled by the amount of fuel consumed. For example, to find miles per gallon (mpg), divide the total miles driven by the gallons of fuel used. This can be done by tracking the odometer readings and fuel fill-ups. The formula is: mpg = total miles / total gallons consumed.

A »To calculate your vehicle's fuel economy, fill up your tank and reset the trip odometer. Drive until you need fuel again, then note the miles driven and gallons used to refill. Divide the miles by the gallons to get miles per gallon (MPG). For example, if you drove 300 miles and used 10 gallons, your fuel economy is 30 MPG. This helps track efficiency and plan for fuel costs!

A »To calculate fuel economy, divide the total distance traveled by the total fuel consumed. For example, if a vehicle travels 300 miles on 15 gallons of fuel, its fuel economy is 300 miles / 15 gallons = 20 miles per gallon (mpg).
