Frequently Asked Questions

How does a propane vehicle work?

Propane engines are spark-ignited, internal combustion engines, designed much like gasoline vehicles There are two types of propane engines: Dedicated (100% propane) and Bi-fuel (50% gasoline, 50% propane).

How much do you save when converting your vehicle to propane?

Propane is generally 30% cheaper over gasoline. Private fleets with their own propane pumps and tank pay a much lower price than the retail fuel pump cost. 

 

Example: If regular gasoline is at an average of $4.50/gal, Autogas propane is at an average of $3.59/gal. If you run on 20 gallons of regular gasoline per week for instance, you could save over $70 per month and over $800 per year on propane.

 

In addition to a reduced fuel cost, propane engines require less oil and filters. That’s because there’s minimal carbon buildup from propane. Overall oil, filters and labor are significantly less on a propane engine. 

 

Fleets owners save nearly 50% on fuel and maintenance costs compared to gasoline or diesel.

Is propane a clean alternative fuel?

Yes, the EPA considers propane as a clean alternative fuel under the Energy Policy Act of 1992.

How is propane cleaner than other vehicles?

Propane autogas vehicles cut significantly more NOx (Nitrogen oxides) and greenhouse gas emissions compared to diesel and gasoline. The EPA considers propane a clean fuel. Propane is known as the number one alternative fuel around the world.

Is a propane engine viable?

Propane vehicles have been widely used and refined for decades, and a propane vehicle’s power, acceleration, and cruising speed are similar to those of conventionally fueled vehicles.

How safe is propane Autogas?

Propane Autogas is nontoxic, has a lower flammability range than conventional gasoline, and odorized for easy detection. Their Containers are equipped with safety devices, including pressure-relief valves, shut-off valves that detect fuel line ruptures (due to collisions on the road), and overfill protection. As well as being constructed from carbon steel and are 20 times more puncture-resistant than conventional gasoline and diesel tanks. 

Can a propane vehicle run on gasoline too?

You can either buy a propane vehicle with a Dedicated Propane Engine or you can have your vehicle converted with a Bi-Fuel Engine so it runs on both gasoline and propane.

What are the miles per gallon of Propane compared to Gasoline and Diesel?

1 Gallon of Propane is equivalent to  0.67 Gasoline Gallon Equivalent

1 Gallon of Propane is equivalent to 0.59 Diesel Gallon Equivalent

Why aren’t there more propane powered vehicles on the road?

One reason is the development of fueling stations throughout the country. Most have been built around delivering gasoline, and as a result has driven the bulk of the automobile market toward gasoline. In recent years, however, Autogas refueling locations are slowly popping up across the state.

What funding is available to help me get my vehicle/fleet converted to propane?

 The Ohio Propane Gas Association offers a $4,000 rebate (up to $20,000) to Ohio residents that are either buying a new propane vehicle, converting their vehicle to propane OR a lawn mower.

Frequently Asked Questions

How does a propane vehicle work?

Propane engines are spark-ignited, internal combustion engines, designed much like gasoline vehicles There are two types of propane engines: Dedicated (100% propane) and Bi-fuel (50% gasoline, 50% propane).

What is a Dedicated Propane Engine?

A Dedicated Propane Engine is an engine installed in a vehicle so that it runs solely on propane and can be ordered or purchased straight from the manufacture or your local dealership.

Where can I go to order a Dedicated Propane Vehicle?
Your local dealership can help you and/or order a dedicated propane vehicle for your fleet.
What is a Bi-Fuel Propane Engine?

A Bi-Fuel Propane Engine is an engine installed in a vehicle where it runs on propane and the original fuel (gasoline or diesel). Vehicles can be converted by a qualified system retrofitter (QSR) to light, medium or heavy-duty vehicles and can be as quick as one day to install.

What types of Autogas Systems are used in vehicles?

The most common systems are the vapour sequential injection and liquid injection systems. 

 

The Vapour sequential injection system injects the fuel in a gaseous phase but aligns the gas injections to what the original electronic gasoline controls of the car command.

 

The Liquid injection system exactly replicates gasoline systems and injects the fuel in a liquid phase without prior vaporisation. This enables more precise metering of the fuel and an injection timed to the opening of the intake valves.

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.

What is the torque comparable to gasoline?

Vehicles equipped with ROUSH CleanTech’s propane autogas fuel systems retain equivalent horsepower, torque, towing capacity and warranty coverage as gas and diesel counterparts.

Will I get the same response when I step on the gas pedal?

A propane vehicle’s power, acceleration, and cruising speed are similar to those of conventionally fueled vehicles.

How often do you have to change oil or spark plugs?

Follow the manufacturer’s recommended oil change intervals, but be aware that the oil may not look like it needs changing because propane burns cleaner. The oil still needs to be changed at the recommended interval, there are necessary protective additives in engine oils that can still wear out. Some regular propane fuel users report that they can wait until 15,000 miles before needing an oil change.

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.

What effect does propane have on the vehicle’s carburetor?

An engine that runs on propane will generally run longer and require less maintenance than running on gasoline. Propane is a lot easier to vaporize in the carburetor and propane, being gaseous at atmospheric pressure and temperatures, won’t leave deposits behind. 

What effect on does propane have on the fuel injectors of a vehicle?

The operation with alternative fuels have no negative effects on engine wear rates and durability. Engine thermal loads are equivalent to 100% diesel operation, no excess wear of combustion chamber components.

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.

What happens when I run out of propane and it switches back to gasoline while I am driving with a Bi-Fuel system installed?

The pressure in the engine goes down due to the propane tank losing pressure from the lack of propane. Each injector in the engine, that once ran on propane, turns to run on gasoline automatically. This process does not hurt the engine while you are driving.

Does getting my new vehicle converted to propane affect the manufacturer's’ warranty?

No, the manufacturer’s’ warranty is not affected when you get your vehicle converted to propane.

Is there any Manufacturer warranties on systems?

Alliance Autogas offers a 5-year / 100,000-mile warranty covering all parts of the system.

 

The ROUSH CleanTech propane auto-gas fuel system is covered by a limited 1-year / 12,000-mile warranty

 

Check with your propane autogas manufacturer to see if they offer a warranty for the conversion system you chose.

How readily available are parts for propane vehicles?

Propane parts are available from original equipment manufacturers (OEM’S) or contact your local propane conversion company.

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.

How much does it cost to get my vehicle converted to propane?

On average, a propane vehicle conversion can cost anywhere from $6,000 to $9,000 depending on the vehicle and kit installed.

Where can I go to get my vehicle converted to propane?

Ohio has 2 Autogas conversion locations.
