Propane Vehicle Conversions
Vehicle conversions provide alternative fuel options beyond what is available from original equipment manufacturers (OEMs). Certain light-duty vehicles can be ordered from a dealer with a prep-ready engine package and converted to use propane. Qualified system retrofitters (QSRs) work with the dealer to install conversions to a dedicated or bi-fuel propane fuel system. QSRs can economically and reliably convert new or existing light- or medium-duty vehicles for propane operation. These vehicles must meet OEM emissions standards for the given model year and once converted, can be dedicated or bi-fuel propane-powered vehicles.
Propane vehicle conversions in the United States require U.S. Environmental Protection Agency (EPA) approval and a QSR should perform the installation. For more information about regulations, codes, and standards, see the AFDC's Conversions page.
The cost to convert a light-duty vehicle from gasoline to propane use ranges from $4,000 to $12,000. The upfront costs to convert fleet vehicles to propane can be offset by lower operating and maintenance costs over the lifespan of the vehicles. Conversion to a dedicated or bi-fuel propane vehicle can be an attractive option when fueling infrastructure is in place and volume fuel discounts are available. The payback period depends on the average distance traveled by fleet vehicles and installation costs. Fleet vehicles typically are high-mileage, high-fuel-consumption vehicles operating in a limited area, so the payback period on propane fleet vehicles can be very quick.
