Frequently Asked Questions: Propane Autogas Technology

This is the second post of a two-part series to answer some frequently asked questions about propane autogas and autogas vehicles. Today we’re answering questions about propane autogas technology.

Can my vehicle be converted to run on propane autogas?

The Alliance Autogas website has a list of vehicle makes and models that are eligible for conversion with the Prins Vapor Sequential Injection system. Alliance AutoGas currently has certifications for several Ford, GMC, Lincoln, and Chevrolet models. The U.S. Department of Energy′s Alternative Fuels & Advanced Vehicles Data Center website also has a lot of information about propane autogas vehicle conversions. Vehicle conversion equipment in the U.S. must receive approval and certification from the U.S. Environmental Protection Agency before they can be used.

Even if your vehicle is not eligible for conversion, you may consider purchasing an OEM autogas vehicle when it is time to replace your vehicle. Several manufacturers, such as ROUSH CleanTech, Blue Bird Corp., and GM offer OEM-equivalent autogas vehicles. These vehicles are usually eligible for the same federal incentives as converted vehicles and result in long-term savings that can offset their purchase cost.

How do bi-fuel vehicles work?

Bi-fuel propane autogas vehicles can run on either autogas or gasoline. With the Prins fuel system, vehicles will switch automatically to gasoline if the tank is low on autogas.

How do I refuel my autogas vehicle?

Like gasoline, autogas is bought by the gallon and pumped in liquid form into the tank via a hose. It becomes a gas just before entering your vehicle engine’s combustion cylinder.

What’s the cost of converting a vehicle to autogas?

The cost of converting a light-duty vehicle to propane autogas ranges from $4,000 to $12,000, according to the U.S. Department of Energy′s Alternative Fuels & Advanced Vehicles Data Center (AFDC). Federal incentives can offset some of these costs, and many fleets find the fuel and maintenance savings yielded from using autogas completely recoup the cost of conversion.

What is involved in converting my car to autogas?

Bi-fuel aftermarket conversion systems enable vehicles to run on either autogas or gasoline. A separate fuel system and fuel tank are also added to the car. The tank is usually fitted in the trunk, but can sometimes be installed underneath the car.

Will the conversion affect my vehicle’s warranty?

Most conversions do not void the factory warranty, since the system is placed over the existing gasoline systems and does not change the factory vehicle parts or assembly. Warranties are also available to cover autogas conversion systems. If you choose to remove an autogas vehicle from service in your fleet, some propane autogas systems can be transferred from one vehicle to another of the same make and model.
