Propane Interest Groups



  • The vast majority of propane consumed in the United States is produced here and distributed via an established infrastructure.
  • Using propane vehicles instead of conventional vehicles reduces U.S. dependence on foreign oil and increases energy security.
  • A variety of light- medium- and heavy-duty propane vehicle models are available through original equipment manufacturers (OEMs) and select dealerships.
  • The cost of propane is lower than gasoline so the return on investment can be quick.
  • Fleets and consumers also have the option of converting existing light- medium- and heavy-duty gasoline or diesel vehicles for propane operation using qualified system retrofitters.
  • Typically in fleet applications propane costs less than gasoline and offers a comparable driving range to conventional fuel.
  • Propane's high octane and low-carbon and oil-contamination characteristics have resulted in greater engine life than conventional gasoline engines.
  • Because the fuel's mixture of propane and air is completely gaseous cold start problems associated with liquid fuel are reduced.
  • Propane is nontoxic. nonpoisonous. and insoluble in water.
