Question 1

How do I calculate my car's average consumption?

Accepted Answer

Fill up, note the odometer, drive until the next fill-up, note the odometer again and the litres bought. Consumption = litres ÷ km × 100.

Question 2

How do I calculate how many litres I need for a trip?

Accepted Answer

Kilometres × consumption ÷ 100. For 300 km at 6.5 l/100 km you need 19.5 l. Multiplied by the price per litre gives the trip cost.

Question 3

What is standard consumption?

Accepted Answer

The fuel quantity resulting from the kilometres driven multiplied by the vehicle's own consumption norm. It is the consumption justified in the trip sheet, unlike real consumption, which is what you bought.
