Liquefied petroleum gas or condensed oil gas or fluid oil gas (LPG or LP gas), is a combustible blend of hydrocarbon gases utilized as fuel in warming machines, cooking hardware, and vehicles. It is progressively utilized as a vaporized force and a refrigerant supplanting chlorofluorocarbons with an end goal to lessen harm to the ozone layer. At the point when explicitly utilized as a vehicle fuel it is regularly alluded to as autogas. Assortments of LPG purchased and sold incorporate blends that are generally propane (C3H8), for the most part butane (C4H10), and, most normally, blends including both propane and butane. In the northern half of the globe winter, the blends contain more propane, while in summer, they contain more butane.

Propylene, butylenes and different hydrocarbons are typically additionally present in little fixations. HD-5 restrains the measure of propylene that can be put in LPG to 5%, and is used as an autogas detail. An incredible odorant, ethanethiol, is included with the goal that breaks can be recognized without any problem. The globally perceived European Standard is EN 589. In the US, tetrahydrothiophene (thiophane) or amyl mercaptan are additionally affirmed odorants, albeit nor is as of now being used.
