85. 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.

How do I know which fuel my vehicle needs?
Check the vehicle manufacturer's instructions and the fuel information shown near the filler opening or on the vehicle. Fuel pumps are normally labelled to help drivers identify compatible fuels.
How can a driver reduce fuel consumption?
Smooth acceleration, anticipating traffic, maintaining an appropriate speed, correct tyre pressure, avoiding unnecessary loads and keeping the vehicle properly maintained can help reduce fuel consumption.
