Propane Autogas


Propane gas has been a commercial engine fuel for over 80 years powering more than 4 million vehicles across the world. Propane is the third most popular engine fuel after gasoline & diesel fuel. Propane is clean, cost effective, safe and a reliable alternative fuel.

Clean Alternative Fuel: Going Green!


Tests by the USEPA show that propane powered vehicles can produce 30 – 90% less toxins and smog-producing carbon monoxide and approximately 50% less toxins & other smog producing emissions than gasoline engines. The USEPA projects that propane will be the leading alternative fuel in the 21st century.
Government & private fleets will soon be required to change to alternate fueled vehicles to reduce the harmful emissions from fossil fuels – the leading source of air pollution & green house gas emissions in the USA. Propane is an approved alternative fuel in the US Energy Policy Act of 1992.

Engine Performance:

  • Of all alternative fuels available, propane offers the best mix of durability, performance and driving range.
  • Clean burning: Many fleet owners report on the average, an extended 3 years service life and extended service intervals between required maintenance. Engines can last 2 times longer than gasoline engines and spark plugs from a propane powered vehicle last from 80,000 t0 100,000 miles.
  • Propane vehicles have the longest driving range of all clean-burning fuels.
  • Bi-Fuel Ability: Today’s conversion kits allow fuel injected engines to run on either propane gas or gasoline extending your driving range if away from your home supply area. No adjustments are needed, simply flip a dashboard switch and chose your fuel to run on.

Typical Propane Autogas Fill Stations

  • Propane Autogas
  • Propane Autogas


A wide variety of sizes & shapes are available to fit just about any vehicle on the market. These tanks are over 20 times thicker than a standard gasoline tank and come equipped with safety valves that shut the flow of gas if a fuel line were ever severed.

Propane gas has an extensive price & tax advantage over gasoline today. Many fleet owners can expect to save 50-70% on annual fuel expenditures over gasoline. In addition to the savings on the cost of fuel, there are both federal and state tax incentives for conversions to clean burning alternate fuels. These tax credits = big savings to you as the fleet owner.
