3/22/2010 · To calculate fuel consumption, start by writing down how many miles you have on your car and then filling up the gas tank. Then, drive your car around until the gas tank is nearly empty. When the tank is almost empty, refill it and write down how many gallons of gas you needed and how many miles you've driven since the last time you filled up.

Consumption of natural gas vehicles is, however, most often expressed in kg/100km. Different types of natural gas are available in Belgium, roughly divided into two categories: low and high calorific gas (L- and H-gas). CO2 emissions differ between both categories, and strongly depends on the composition and origin of the gas.
