Propane/Autogas Conversions and Refueling
Why convert to propane/autogas?
There are many great advantages for converting to propane.
Autogas is less expensive than gasoline: Autogas costs about $2.00/g. There are different types of autogas systems. With some systems, there is no change in fuel economy. On other systems you may lose up to 10% fuel economy but gain up to 10% torque. In such a circumstance one can consider propane to effectively cost $2.20/g when calculating return on investment.
Less dependence on foreign countries for fuel.
97% of autogas is refined in the US.
Autogas is better for the environment.
Companies and municipalities with fleets of vehicles are at an advantage especially when they use the same make and model of vehicle for propane conversions. See the Fleet section below for more information.

Can I still use gasoline?
Yes, you can use either propane or gasoline after conversion. Most conversions have been dual fuel and keep the gasoline system while adding a completely separate autogas system from fuel tank to fuel injector. However, as the number of autogas filling stations increases, we anticipate more dedicated conversions to autogas.
What does it cost to convert, and what are fuel costs?

Is propane/autogas safe?
Propane/autogas is considered to be safe. Some argue that it is safer than other fuel sources.
Fleet vehicle conversion cost information
Here are two examples of what it would cost to convert a single certified vehicle, and convert a fleet of vehicles that are the same make and model:
Types of autogas conversions
Most early systems have been vapor systems which inject propane in its vapor state into the intake manifold. ICOM has a new system that injects liquid propane into the intake manifold. Vapor systems cost about $5000 and $7000 installed. ICOM's system is about $7000-$9000 installed. A liquid injection system costs between $8,000 and $10,000.
In order to qualify for the rebate, the system needs to be certified by the EPA as meeting or exceeding the original emissions. Many systems have already been EPA certified, but if your year, make and model have not already been certified, then there would be an additional charge to get the certification. EPA certification costs about $6000 to 7000.
