144. Fuel
Fuel is a source of energy used to power a vehicle's engine. Common vehicle fuels include petrol, diesel, LPG, CNG and alternative fuels. Electric vehicles use electricity rather than conventional liquid or gaseous fuel.
Drivers should always use a fuel that is compatible with their vehicle. Using the wrong fuel can damage the engine or fuel system, while economical driving and proper vehicle maintenance can reduce fuel consumption.
