Propane or liquefied petroleum gas (LPG) is a clean-burning fossil fuel that can be used to power internal combustion engines. Liquefied petroleum gases (LPG) are produced from associated petroleum gas.

These are pure gases or special mixtures that can be used to heat buildings, to produce petrochemicals and as a motor fuel.

LPG-fueled vehicles can produce significantly lower amounts of some harmful emissions and the greenhouse gas carbon dioxide (CO2).

LPG has a good caloric value; used as cooking fuel; because LPG has no natural odour, a distinctive odorant is added so that it will be noticeable should a leak occur.
