Frequently Asked Questions
Alliance AutoGas is the only complete program to help American fleets transition from gasoline to autogas, the world’s most popular alternative fuel.  The foundation of Alliance AutoGas is a broad network of partners with expertise in autogas fueling, vehicle technology, and high-performance support.
Autogas is comprised of three parts carbon and eight parts hydrogen making it a highly efficient, low carbon fuel. It is a safer, less expensive alternative fuel with fewer emissions than gasoline.
100% of Alliance’s autogas is produced in the North America. Autogas comes from two domestic processes: it is a by-product of both natural gas processing and the crude oil refining process.
Yes. Autogas is an approved, alternative clean fuel listed in the 1990 Clean Air Act and National Energy Policy act of 1992. It is a fuel that burns more cleaner than gasoline, is largely produced in the United States and lowers fuel costs.
An autogas bi-fuel vehicle is a conventional gasoline vehicle that has been converted to run on both autogas and gasoline. The primary advantage of a bi-fuel system over a dedicated ‘autogas only’ vehicle is its elimination of range anxiety compared to conventional alternative fuel vehicles.  In the event that a driver has traveled out of range of an autogas refueling station, the vehicle can run on gasoline until an autogas station is reached. For example, if a law enforcement vehicle on a pursuit or other critical mission runs out of autogas, the vehicle will automatically revert to gasoline and vehicle operation will not be impacted.
No. Alliance AutoGas conversion systems have gone through rigorous Environmental Protection Agency (EPA) testing which includes rolling road dyno emissions testing and even engine dyno cell testing. Our conversion systems are also engineered for a specific vehicle platform rather than a box of universal parts.
The Alliance AutoGas conversion system is Environmental Protection Agency (EPA) certified to support many vehicle makes and models. Click here for a full list of vehicles that can be converted.
Technically, any spark ignited engine can be converted to run on autogas. Due to governmental regulations, Alliance AutoGas must develop specific systems within these guidelines. We determine specific vehicle platforms that are used in multiple industry applications based off of customer demand.

Depending on your fleet size and gallon usage, Alliance AutoGas will supply you with your own autogas refueling station at little to no cost. Alliance AutoGas has one of the largest national autogas refueling networks. Contact us to learn about the strategically placed refueling stations in your area or to apply for our refueling card, giving your fleet access to the Alliance AutoGas refueling network.
It is safer and easier to fill your vehicle with autogas compared to gasoline. Unlike gasoline, an autogas dispensing nozzle can not spray fuel unless connected to the vehicles refueling connector. Autogas dispensers refill on average at 10-12 gallons per minute making it one of the fastest alternative fuels to refuel.
Autogas has been less expensive than conventional gasoline over the last two years. Generally, cost savings are between 30% and 50%.
Autogas has a number of benefits:

  • 100% of Alliance AutoGas comes from North America.
  • Autogas is less expensive than gasoline or diesel.
  • Autogas produces fewer harmful emissions than gasoline or diesel.
  • Autogas increases the life of an engine.
  • Less vehicle maintenance is required on autogas vehicles, and because autogas burns cleaner, oil changes are required less frequently.
  • Drivers report that, compared to conventional gasoline, autogas provides superior performance and equivalent power.
The average cost to convert a fleet vehicle from conventional gasoline to run on autogas is $5,800 installed. The cost can vary slightly depending on the type and quantity of vehicles you are converting.
Alliance AutoGas conversion systems come with everything needed for a properly trained technician to convert your vehicle. Including all brackets, hoses, mounts – all the way down to the nuts and bolts.
Yes. Alliance AutoGas conversion systems meet the Environmental Protection Agency’s (EPA) most current emissions standards resulting in greatly reduced emissions compared to gasoline.
Alliance AutoGas Engineered Conversion Systems have been designed for ease of installation. In 2016, two highly trained technicians converted a 2015 Ford F-150 at the National Work Truck Show (NTEA) in a record-setting 1:32 minutes and then drove cross-country on the newly converted autogas system. Typically a trained technician can convert a vehicle in around 6 hours or less.
Yes. Alliance AutoGas Engineered Conversion Systems are backed by a 5-year / 100,000-mile warranty covering all parts of the system as well as any OEM parts directly damaged from failed conversion system components.
No. The Magnuson-Moss Warranty Act of 1975 protects anyone converting a vehicle to autogas with an Environmental Protection Agency (EPA) certified system. Our warranty simply supplements a factory warranty to provide coverage for Alliance AutoGas Engineered System and its components. If any OEM components are damaged by the conversion system, the Alliance AutoGas Engineered System warranty will cover those components as well.
Yes. A 2016 test of a Ford Transit with a 3.7L V6 engine, showed that using the Alliance AutoGas Engineered System significantly reduced greenhouse gas emissions when compared to the same vehicle running on gasoline:

Through a rigorous Environmental Protection Agency (EPA) testing protocol, autogas has clear, proven benefits over gasoline:

  • Reduces carbon monoxide (CO) by 79.45%
  • Reduces carbon dioxide (CO₂) by 22.39%,
  • Reduces nitrogen oxide (NOₓ) by 42.31%
  • Reduces non-methane hydrocarbons (NMHC) by 53.97%
Alliance AutoGas doesn’t want just a customer, we want alternative fuel partners.

With this attitude, Alliance AutoGas team members will work hand-and-hand with fleet managers throughout the entire rollout process with continued interaction for the success and growth of the fleet. From presentations to upper management to ROI calculations, our team is there to provide the knowledge the fleet manager needs.

Yes. Autogas vehicle tanks are made from high carbon steel and are 20 times more puncture resistant than conventional plastic gasoline tanks. Autogas is nontoxic, nonpoisonous, not a groundwater contaminant, and has the lowest flammability range of any alternative fuel as well as gasoline.
