Aviation fuel is a specialized type of petroleum-based fuel (actually Propellant) used to power aircraft. It is generally of a higher quality than fuels used in less critical applications, such as heating or road transport, and often contains additives to reduce the risk of icing or explosion due to high temperature, among other properties.

Most aviation fuels available for aircraft are kinds of petroleum spirit used in engines with spark plugs (i.e. piston and Wankel rotary engines), or fuel for jet turbine engines, which is also used in diesel aircraft engines.

Kerosene is a combustible hydrocarbon liquid widely used as a fuel, in industry, and in households. Its name is derived from Greek: κηρός (keros) meaning wax, and was registered as a trademark by Abraham Gesner in 1854 before evolving into a genericized trademark. It is sometimes spelled kerosine in scientific and industrial usage.[1] The term "kerosene" is common in much of India, Canada, the United States, Australia and New Zealand.

Kerosene is usually called paraffin in the UK, Ireland, Southeast Asia and South Africa. A more viscous paraffin oil is used as a laxative. A waxy solid extracted from petroleum is called paraffin wax.
