Calculate dieselforbrug
Find your car's real dieselforbrug: fill the tank, drive, fill again and enter the km driven and litres filled.
How to measure consumption
Fill the tank completely and reset the trip meter. The next time you fill up completely, enter the km driven and the number of litres. Km per litre = km ÷ litres.
Measure over several fill-ups for a more accurate figure. Cold, short trips, high speed and a roof box raise consumption.
