Benefits of Propane Vehicle Conversions

Any gasoline-powered vehicle can be converted to propane autogas. To find out more about your vehicle and the best conversion process, email us at info@PropaneAutoGasLLC.com.

An increasing number of high-demand light- and medium-duty trucks, vans, cars, and chassis models can be converted to operate on propane autogas as the primary fuel and gasoline as the secondary fuel using an EPA or CARB-certified conversion kit. We work with our partners who are certified propane conversion experts to make sure we select the right conversion kit for your fleet.

Propane autogas is listed as an Ultra Low Emissions Vehicle (ULEV). Being a ULEV, propane autogas is one of the cleanest burning fossil fuels.

Due to low carbon content and higher octane resulting in a cleaner-burning fuel, vehicles that run on propane require less maintenance and upkeep.

How Do I Know If Propane Is Right for My Fleet?

Will a propane conversion hurt my engine?

No. Burning propane in your engine should extend its life compared to burning gasoline. Propane burns cleaner than gasoline, so there are fewer impurities in the cylinder to cause wear and the engine oil stays cleaner and lasts longer. Most fleet managers report longer engine life on their propane-equipped vehicles versus gasoline.

Will a propane conversion void my warranty?

It depends on the vehicle, and the kit used. In most cases, it does not.  If you are about to buy a new vehicle, please call us and we can advise about special options to select in order to make a propane conversion easier.

Where does the propane tank go?

Most conversion kits feature a tank specially designed to fit in a vehicle’s spare tire carrier location. If you don’t wish to sacrifice your spare tire room, extended range tanks of 50 to 80 gallons are available for mounting in truck beds or frame mounting on vehicles that have space available for it. For vehicles converted to a dedicated propane system, a propane tank can usually be fitted where the gasoline tank was previously.

Does my conversion have to be EPA Certified?

For newer vehicles, the conversion kit must be EPA certified to be legal to use in the United States. Older vehicles that are more than 10 years old or have over 120,000 miles are sometimes exempt from this rule, as they are considered “beyond useful life,” by the EPA. EPA-approved kits are available for most naturally aspirated engines used in fleet vehicles, SUVs, and some passenger cars.

Can I buy a propane vehicle from a dealer?

Yes! Ford, General Motors, Freightliner, and several other manufacturers offer vehicles that are converted to autogas after rolling off the assembly line by a Qualified Vehicle Modifier and have full warranty coverage and serviceability at the dealership they came from. 

Is the conversion reversible? How much modification is done? Will my check engine light come on?

The ICOM propane conversion does not splice into the factory wiring harness or fuel system at all, and will not cause any warning lights to come on. The only wiring into the vehicle is to the battery and 1 wire to a spark plug for RPM monitoring.

Since holes must be drilled into the intake manifold for injector placement, (for a bi-fuel conversion) reversing a conversion may require installing a new intake manifold or plugging these holes in some other way.

A properly installed and tuned conversion should, in most cases, not cause any trouble for a vehicle’s onboard diagnostic systems or ECM/ECU.
