Propane: Liquefied Petroleum Gas (LPG). Propane, or liquefied petroleum gas (LPG), is a clean-burning fossil fuel that can be used to power internal combustion engines. LPG-fueled vehicles can produce significantly lower amounts of some harmful emissions and the greenhouse gas carbon dioxide (CO 2). LPG is usually less expensive than gasoline, it can be used without degrading vehicle performance, and most LPG used in U.S. comes from domestic sources. The availability of LPG-fueled light-duty passenger vehicles is currently limited.
There are a number of gases that fall under the âLPGâ label, including propane, butane, propylene, butadiene, butylene and isobutylene, as well as mixtures of these gases. Propane does not occur naturally. LPG is produced during natural gas processing and petroleum refining.ollowing its refinement, LPG is stored as a liquid under pressure until used, at which point it becomes a gas or vapour. In Australia, LPG is Propane. Propane is a three carbon molecule with the formula C3H8.
