Cut Fuel Costs and Protect the Environment

Energy Independence with Domestically-produced Propane
Fleet BenefitsAbout Propane Auto Gas LLC

More Savings & Efficient Fuel

An investment in propane autogas leads to considerably lower life-cycle vehicle costs for fleets. Diesel, gasoline, and other alternative fuels burden budgets with costly infrastructure and maintenance demands. Vehicles are proven to last 2-3 years longer. Actual savings will vary based on fleet size, annual mileages, the weight of the payload. 

Easy Refueling

Unlike conventional fuels, propane autogas provides an affordable infrastructure solution for fleets that need a central refueling location. Personal vehicle owners can also enjoy the growing number of  propane autogas stations. There are propane autogas refueling stations in every state, with more opening every day.

U.S. Produced Propane

Supporting our domestic economy is easy with propane autogas. 98% of American autogas is produced in the U.S. Using autogas means reducing our dependence on foreign oil and creating jobs here in America.

Proven Technology

Fleets and personal vehicle owners can choose from a wide variety of OEM-supported vehicles that are EPA- and CARB-certified. Many provide equal horsepower, torque, and towing capacity to conventional versions of the same models.

Drive Green

Propane autogas is an economical approach to significantly lower harmful emissions. Vehicles fueled by  propane autogas emit 25% fewer greenhouse gas emissions than vehicles running on gasoline. Propane autogas also cuts smog producing hydrocarbons by up to 70%.

Reliable & Trusted

Because propane autogas is stored onsite or delivered by your local supplier, propane is always there when you need it. From farms to school bus fleets, to homes and businesses across the country, propane is helping users reduce their emissions and save more money.

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.
