Fuel Consumption Calculator | AA Inform
Petrol consumption is the amount of petrol you consume while driving. It includes not only the amount of fuel you burn in the engine but also the amount of fuel that is lost in the exhaust pipe and the amount of energy that goes to waste due to incomplete combustion. Fuel consumption is measured in litres per 100km (L/100km).
