MPG Formula

The MPG calculation is based on two main factors: distance traveled and fuel used.

Formula:
MPG = Distance / Fuel Used
Steps

How to Calculate MPG

To calculate your vehicle's MPG, follow these steps:

  1. 1
    Fill up your gas tank completely
  2. 2
    Reset your trip odometer to zero
  3. 3
    Drive normally until you need to refuel
  4. 4
    Note the distance traveled from your trip odometer
  5. 5
    Fill up your tank again and note the gallons used
  6. 6
    Divide the distance by the gallons used to get MPG
Tips

Understanding Fuel Efficiency

Fuel efficiency can vary based on several factors:

  • Vehicle type and model
  • Driving conditions (city vs. highway)
  • Driving habits and speed
  • Vehicle maintenance
  • Weather conditions
Tip:
For more accurate MPG calculations, measure over longer distances and multiple fill-ups to get an average.
Examples

Practical Examples

Example 1 City Driving

A car travels 250 miles and uses 10 gallons of fuel.

MPG = 250 miles / 10 gallons = 25 MPG

Example 2 Highway Driving

A car travels 400 miles and uses 12 gallons of fuel.

MPG = 400 miles / 12 gallons = 33.3 MPG
