How it is calculated
Cost/100 km = L/100 km × price per litre

Consumption of 8 L/100 km at 2.2 per litre costs 17.6 per 100 km or 0.176 per kilometre.
Important notes
This is fuel cost only and excludes tyres, maintenance, insurance and depreciation. Use vehicle cost per km for a broader ownership cost.
