The driving range will greatly depend on the size of the tank on the vehicle.  For pickup trucks, tanks located in the bed offer higher capacities and can give you a range of up to 450 miles on Autogas.  While tanks located under the bed in the spare tire compartment can give you a range of up to 225 miles.  For vans, under bed tanks can give you a range of about 300 miles.  For cars, such as the Ford Crown Victoria, the tank is located in the trunk and can give you a range of about 300 miles.

Keep in mind that with a bi-fuel conversion, you almost double the driving range of the vehicle because once you use up the propane, the vehicle will then run on gasoline. 

Typically for an Autogas-powered vehicle, you can expect to get about 90% of the fuel economy you were getting from a comparable vehicle on gasoline.
If you have your own mechanics, our conversion kit manufacturing partners can provide the necessary training for your mechanics to properly maintain the conversion system.  If that is not an option for you, we have partners that can provide maintenance and repair services. 
If you choose an OEM vehicle from ROUSH, GM, Blue Bird or Collins, their warranty will cover the propane system.  For aftermarket conversions, those manufacturers have their own warranty for their systems.
We have partnered with several aftermarket conversion kit manufacturers and installers.  Georgia Gas can coordinate the conversion and installation process for you or, depending on the system you choose, if you have your own mechanic and/or maintenance shop, our partners will provide the necessary training for you to do the conversion. 
Autogas is really the only alternative fuel readily available today that is economically justifiable.  The price of Autogas can be 30 to 40% less than gasoline.  There are also federal tax credits currently available for running vehicles on propane.  In addition, engines that run on Autogas have a lower cost of ownership than traditional fuel vehicles.

All these elements come together and allow you to more than pay for the cost of the conversion over the life of the vehicle.  (see our payback calculator) 

Costs will vary depending on the type of vehicle, the conversion system used and the fuel tank size.  Bi-fuel aftermarket conversion systems can cost in the range of $5,000 to $6,500 including installation.  OEM equipped dedicated propane fueled vehicles from Ford/ROUSH (pickups and vans) cost about $10,000 for the system. 
More than 14 million vehicles worldwide run on Autogas.  Autogas is extremely safe even when compared to traditional fuels.  Propane tanks are made of steel and are about 20 times more puncture resistant than typical vehicle fuel tanks. 
  • Compared to gasoline, Autogas exhaust yields 60% to 70% less smog-producing hydrocarbons than gasoline. Autogas also reduces emissions of toxins and carcinogens like benzene and toluene by up to 96% versus gasoline(Southwest Research Institute).
  • Autogas creates 12% less carbon dioxide, about 20% less nitrous oxide and up to 60% less carbon monoxide when compared to gasoline (World Liquid Propane Gas Association, January 2003 – California Energy Commission, January 2003).
  • Autogas has a higher octane rating (104) compared to premium gasoline (91-94). Autogas’ higher rating allows for higher compression ratios resulting in better engine efficiencies and performance.


Propane has been a fuel used for heating homes and businesses, fueling vehicles and many other uses for almost 100 years.  Propane is a by-product of refining oil and natural gas and is a very efficient and clean burning fuel.  Over 90% of America’s propane supply is produced in this country. 
Autogas has become the term used worldwide for propane used to fuel various types of on-road vehicles.
