Kerosene

Kerosene or paraffin oil (British English, not to be confused with the waxy solid also called paraffin wax or just paraffin) is a flammable hydrocarbon liquid. The name is derived from Greek "keros" (κηρός wax).

Its heating value, or heat of combustion, is around 18,500 Btu/lb, or 43.1 MJ/kg, making it similar to that of diesel. It is widely used to power jet-engined aircraft, but is also commonly used as a heating fuel.
