Getting an honest number

  • Fill the tank to the same point both times — brim to brim is what makes the reading trustworthy.
  • Measure over a few hundred kilometres. One short city trip mostly measures traffic.
  • Already know your km/L and want a trip cost instead? Use the fuel cost calculator.
