Mile for mile, propane autogas simply costs less than gasoline. Lower fuel and maintenance expenses and environmental benefits make propane the ideal alternative to gasoline for vehicle fleets. It’s no wonder propane is the leading alternative fuel in the United States and the third most common fuel for vehicles after gasoline and diesel.

Propane autogas costs less per gallon than gasoline or diesel fuel. According to the Propane Education & Research Council, ThyssenKrupp Elevator Americas saved more than $2,900 per vehicle in 2012.* Fleet owners who use propane autogas can also save money by taking advantage of federal, state and local incentives that may be available to them.

Higher octane ratings allow for higher compression ratios and better engine efficiencies. Many fleets are reporting lower maintenance costs, two to three years longer service lives, and extended intervals between required visits to the shop for maintenance.

Propane autogas provides the longest driving range of the alternative fuels.

  • 250 percent farther than compressed natural gas
  • 60 percent farther than methanol
  • 25 percent farther than ethanol


Propane is an approved clean fuel listed in the 1990 Clean Air Act and the National Energy Policy Act of 1992. Vehicles powered by propane autogas emit 17 percent fewer greenhouse gases into the atmosphere than gasoline-fueled vehicles.**



  • Is nontoxic, causing no harm to soil or water
  • Does not puddle — vaporizes and dissipates into the air
  • Requires a higher temperature than gasoline to ignite
  • Cannot be accidentally ingested

Propane fuel tanks are

  • Twenty times more puncture-resistance than gasoline tanks
  • Equipped with built-in safety devices and automatic shut-off valves
  • Built in several shapes and sizes to best fit individual vehicles

Domestically supplied

Because 90 percent of the propane autogas used in the United States is produced here, our dependence on foreign oil is decreased. Fifty percent comes from processing domestic natural gas and 40 percent is derived from processing domestic petroleum. Seven percent of propane autogas is imported from Canada.
