The Core Concept: Gas Mileage (Fuel Economy) Calculation

A The appFigures out a vehicle's Fuel Economy, which is the distance traveled per unit of fuel consumed. In the US/Imperial system, this is commonly measured in Miles Per Gallon (MPG). Knowing your vehicle's true MPG is essential for budgeting, tracking performance, and diagnosing potential issues.

The figure is a simple division of the distance driven by the figure of fuel worked with to cover that distance.


1. The Mileage Number Formula

To precisely work out MPG, two key readings are called for: the exact distance traveled since the last refueling, and the exact volume of fuel added during the latest refueling.

Gas Mileage (MPG) = Total Distance Driven (Miles) Fuel Added (Gallons)

Note: The Fuel Added (Gallons) is the sum needed to refill the tank back to full, not the total size of the tank.


2. Steps for Manual Result

To figure out MPG manually, the user must record data over at least two fill-ups:

  • Fill-up 1: Note the starting odometer reading (or reset the trip meter) and fill the tank completely.
  • Fill-up 2: Drive normally. Note the current odometer reading and fill the tank completely again, noting the exact number of gallons purchased.
  • Result: Subtract the starting odometer reading from the current reading to get the distance driven. Divide this distance by the gallons purchased at Fill-up 2.

3. Metric Equivalent (Liters per 100 km)

In countries working with the metric system, fuel economy is often measured as Liters per 100 Kilometers (L/100 km). Lower numbers suggest better efficiency.

L/100 km = Fuel Consumed (Liters) multiplied by 100 Distance Driven (Kilometers)
