Liquefied petroleum gas (propane) vehicle
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.

  • Emission Reductions- As a low carbon fuel, LPG can burn cleaner than gasoline.
  • Reduced Costs- Engines running on HD- 5 propane typically require less engine maintenance. Fleet fuel and operating costs can be reduced with private fueling stations.
  • Increased Safety– Propane has greater puncture resistance and lower flammability range than gasoline and diesel.
  • Energy Security- 90 percent of LPG used in the United States is produced domestically (, whereas 40 percent of the U.S. petroleum demand was imported in 2010 (EIA).
