Formula and example

How it is calculated

Consumption in l/100 km = litres / kilometres × 100

Worked example

39 l over 600 km gives 6.5 l/100 km.

Things to check

  • For a meaningful fill-to-fill comparison, use the same tank level at the beginning and end. A single short trip is less representative.
