    Fuel Efficiency Formula — Calculate Your Car's Mileage

    Knowing your vehicle's actual fuel efficiency helps you budget for fuel costs and compare with manufacturer claims.

    Mileage Formula (km/L)

    Fuel Efficiency = Distance Traveled / Fuel Consumed

    Where:

    • Efficiency = Kilometers per liter (km/L)
    • Distance = Distance traveled (km)
    • Fuel = Fuel consumed (liters)

    Step-by-Step:

    1. 1

      Fill tank completely

      Note the odometer reading.

    2. 2

      Drive normally

      Use the car as usual.

    3. 3

      Refill and calculate

      Note new odometer. Mileage = Distance / Liters filled.

    Worked Examples:

    City driving

    Distance: 350 kmFuel: 25 L

    Result: 14 km/L

    350/25 = 14 km/L
