Fuel Fill-Up Mileage (Actual MPG)
Work out your real fuel economy and cost per distance from odometer readings and the fuel you added, free online.
About this calculator
Fill the tank, note the odometer, drive, then refill and note the litres or gallons needed. Fuel economy = distance driven ÷ fuel added (mpg or km/L), and L/100 km = fuel ÷ distance × 100. Tracking this over several fill-ups reveals engine problems, tyre pressure issues and driving-style savings.
