Our complete, turnkey solution includes vehicle conversions, fleet base fueling station installation, ongoing technical support and fuel. The foundation of Alliance AutoGas is a broad network of partners with expertise in fueling, vehicle conversion, and high performance support.

Propane autogas is propane condensed to a liquid. It is a safer, less expensive fuel with fewer emissions than gasoline.

Over 90% of Alliance’s propane autogas is produced in the United States. Propane autogas comes from two domestic processes: it is a by-product of both natural gas processing and the crude oil refining process.

Yes. Propane 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 cleanly than gasoline, is largely produced in the United States and lowers fuel costs.

A propane autogas bi-fuel vehicle is a conventional gasoline vehicle that has been converted to run on both propane autogas and gasoline. The primary advantage of this bi-fuel system over a dedicated ‘propane only’ vehicle is the peace of mind it provides for fleet managers and drivers: 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, in the event that a law enforcement vehicle on a pursuit or other critical mission runs out of propane autogas, the vehicle will automatically revert to gasoline and vehicle operation will not be impacted.

The Alliance AutoGas conversion system is EPA certified to support the following makes and models:

Good candidates for conversion to propane autogas include: taxis, police vehicles, shuttle vans, limousines, town cars, food and beverage distribution trucks, utility trucks and many more.
Most of Alliance AutoGas’ customers are fleets because fleets have several key characteristics:

• The vehicles travel to a home base regularly, which serves as a re-fueling station
• The vehicles travel a high number of miles every year in a given footprint, which allows fleets to offset the cost of conversion due to fuel cost savings
• The vehicles follow a pattern of makes and models – which allows Alliance AutoGas to focus on achieving EPA certification for select makes and models

For a list of vehicles that can be converted please click here. We are continually adding more vehicles to this list.

Our fleet customers refuel at their home bases from a spill-free dispenser installed and maintained by Alliance AutoGas.

Autogas vehicles can also be refueled at any public fueling station that is designed to dispense propane autogas. Click here to view an interactive map where you can find autogas refueling stations.

The process is virtually the same except that the nozzle attaches securely to the vehicle. Propane autogas refuels at roughly 6-8 gallons per minute, the same as gasoline.

Propane autogas has been less expensive than conventional gasoline over the last two years. Generally cost savings are between 30% and 50%.
In addition, fleets receive a federal tax credit of 50 cents per gallon of propane autogas. Alliance is able to offer this tax credit up front so that private fleets can realize the 50 cents per gallon cost saving at time of invoice without applying for the credit.

Autogas has a number of benefits:

• Over 90% of Alliance propane autogas is produced domestically
• Autogas is less expensive than gasoline
• When burned, autogas produces fewer harmful emissions
• 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, when compared to conventional gasoline, autogas provides superior performance and equivalent power

The average cost to convert a fleet vehicle from conventional gasoline to an autogas hybrid is $5,800.00. The cost can vary slightly depending on the type and quantity of vehicles you are converting.

The kit includes:

• Propane autogas fuel tank
• LPG Reducer
• Keihin Fuel Injectors
• Fuel Rail
• ECU (Electronic Control Unit)
• Filter Unit (prevents damage to injectors)
• Fuel Switch (mounts on vehicle dash)
• Solenoid Valves (safety shutoff devices)
• Assorted hoses and fittings
• Remote fill

Yes. Alliance’s Prins VSI system is EPA certified for a wide range of sedan and truck makes and models.

It takes a certified mechanic 15 hours to install the kit.

There is no additional cost to install a fueling site at your fleet base.

Yes. Alliance AutoGas Hybrids are backed by a three year / 36,000 mile warranty covering all aspects of the Prins VSI system. For an additional $250 fee (per vehicle), that warranty can be extended to five years or 100,000 miles.

No. In virtually all cases, converting a vehicle to autogas with Alliance AutoGas does not void your factory warranty. Our warranty simply supplements a factory warranty to provide coverage for Alliance’s Prins VSI system and its components.

Yes. It is an approved, alternative clean fuel listed in the 1990 Clean Air Act and National Energy Policy act of 1992. A 2008 test showed that using a Prins VSI system (the system used by Alliance AutoGas) significantly reduced greenhouse gas emissions when compared to conventional gasoline:

• 16% Reduction in Carbon Dioxide
• 28% Reduction in Carbon Monoxide
• 35.6% Reduction in Hydrocarbons
• 3.7% Reduction in NOx

Test conducted by TUV Product Service (a company recognized for independently testing and certifying conformance to a wide range of international standards, holding over 100 accreditations and approvals) for Prins Autogassystemen B.V.

Alliance AutoGas provides the following expertise to a fleet manager:

• Analyzing fleet vehicle types, quantity and fuel consumption
• Converting vehicles and training fleet mechanics to perform maintenance on the Prins VSI system
• Installing on-site fueling infrastructure
• Training on vehicle use and safety measures
• Training on safe fueling practices
• Developing a plan for guaranteed, ongoing fuel delivery
• Regardless of whether the fleet has an in-house mechanic, Alliance Certified Conversion Technicians are available for ongoing support

Yes. Propane autogas vehicle tanks are 20 times more puncture resistant than gasoline tanks. Propane is nontoxic, nonpoisonous, and has the lowest flammability range of any alternative fuel with a lower flammability than conventional gasoline. Gasoline is combustible at approximately 500 degrees Fahrenheit, whereas propane autogas is combustible at approximately 850 degrees Fahrenheit.
