Why should I convert?

To convert a vehicle to run on AutoGas, a new fuel tank and propane injection system must be installed.  Any gasoline engine can be converted to run on AutoGas, however there are several variables that will affect exactly what type of conversion works best for your own driving habits.

[vc_separator style=”dashed”]

Bi-Fuel vs. Dedicated Mono-Fuel System

A bi-fuel conversion means the vehicle can burn both gasoline and propane. This is the system most motorists opt for, as it allows you to harness all the benefits of propane AutoGas for most of your driving while maintaining the ability to use gasoline where AutoGas is not available. There is no modification to the existing gasoline fuel system with a bi-fuel conversion.

Likewise, a dedicated AutoGas conversion will allow the vehicle to run only on propane, maximizing cost savings. This is a great option for vehicles that run specific routes or within a service area where AutoGas is readily available.

Liquid Injection vs. Vapor Injection

A liquid injection system keeps the propane fuel in liquid form right up to the point it is injected into the engine’s intake manifold. These systems follow the same basic design principle as the factory fuel system and tend to have trouble free performance.  This the best option for most vehicles.

Vapor injection systems convert the propane to gaseous vapor before metering and injecting into the engine. They are usually less expensive than liquid injection systems, but often require more user input and adjustment, and they can be sensitive to extreme temperatures. If considering a vapor injection system, please consult us for advice and assistance.

Frequently Asked Questions About Propane AutoGas Conversions

[vc_toggle title=”Will a propane conversion hurt my engine?” open=”true” el_id=”1456345516925-92175ceb-e58f”]No. Burning propane in your engine should extend its life compared to burning gasoline. Propane burns cleaner than gasoline, so there is less impurities in the cylinder to cause wear and the engine oil stays cleaner and last longer. Most fleet managers report longer engine life on their propane equipped vehicles versus gasoline.[/vc_toggle][vc_toggle title=”Will a propane conversion void my warranty?” el_id=”1456345516957-6221138e-7603″]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, or what OEM options are available.[/vc_toggle][vc_toggle title=”Where does the propane tank go?” el_id=”1456345516989-3e7976fe-7d86″]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.[/vc_toggle][vc_toggle title=”Does my conversion have to be EPA Certified?” el_id=”1456345517023-0eb1e26a-3e69″]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.[/vc_toggle][vc_toggle title=”Can I buy a propane vehicle from a dealer?” el_id=”1456345517055-b66571ce-297b”]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. See what all is available from major manufacturers here.[/vc_toggle][vc_toggle title=”Is the conversion reversible? How much modification is done? Will my check engine light come on?” el_id=”1456345971640-1654b2bd-e15a”]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, it most cases, not cause any trouble for a vehicle’s on board diagnostic systems or ECM/ECU.
