Fuel Consumption Calculator
Find your real fuel consumption from a full tank test.
Consumption = fuel used (L) × 100 / distance (km). MPG = 235.21 / consumption.
How it works
Consumption = fuel used (L) × 100 / distance (km). MPG = 235.21 / consumption.
Worked example
35 L over 500 km = 7 L/100 km, about 33.6 US MPG.
