The gas mileage calculator determines your vehicle's fuel efficiency in miles per gallon (MPG). This helps track fuel economy, identify mechanical issues, and compare vehicle performance over time.
Enter miles driven and gallons used (fill tank, drive, refill and note gallons). The calculator provides MPG, metric equivalent, and an efficiency rating.
Tracking mileage helps you notice changes that might indicate maintenance needs, compare your car's performance to EPA ratings, and make informed decisions about driving habits and vehicle purchases.
