Propane, or Liquefied Petroleum Gas (LPG), is a simple hydrocarbon byproduct of natural gas processing or crude oil refining. The commercial grade of propane for automotive use is known as HD-5 in North America and is also called Autogas.
As a low carbon fuel, LPG can burn cleaner than gasoline. Engines running on HD- 5 propane typically require less engine maintenance. Fleet fuel and operating costs can be reduced with private fueling stations. Propane has greater puncture resistance and lower flammability range than gasoline and diesel. 90 percent of LPG used in the United States is produced domestically (fueleconomy.gov), whereas 40 percent of the U.S. petroleum demand was imported in 2010 (EIA).
