Liquefied Petroleum Gas Writer:Cheng Li Date:2015-10-10

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 (CO2). LPG is usually less expensive than gasoline, it can be used without degrading vehicle performance.

The availability of LPG-fueled light-duty passenger vehicles is currently limited. A few light-duty vehicles—mostly larger trucks and vans—can be ordered from a dealer with a prep-ready engine package and converted to use propane. Existing conventional vehicles can also be converted for LPG use. Since propane is stored as a liquid in LPG storage tanks rated to 300 psi, LPG conversions consist of installing a separate fuel system if the vehicle will run on both conventional fuel and LPG or a replacement fuel system for LPG-only operation.

Advantages and Disadvantages of LPG


90% of propane used inU.S.comes from domestic sources1

Less expensive than gasoline

Potentially lower toxic, carbon dioxide (CO2), carbon monoxide (CO), and nonmethane hydrocarbon (NMHC) emissions


Limited availability (a few LPG tank trucks and vans can be special ordered from manufacturers; other vehicles can be converted by certified installers)

Less readily available than gasoline & diesel

Fewer miles on a tank of fuel
