Converting Vehicles to Autogas is Quick, Safe and Affordable.

Some Alliance AutoGas fleet customers choose to buy new autogas vehicles, but many of our fleet customers choose to convert their existing fleet vehicles from gasoline to propane autogas at no upfront cost with Alliance AutoGas.

Alliance AutoGas uses an aftermarket conversion system from global technology leader, Prins, that is EPA-certified for more than 200 vehicle types. The competitively priced Prins System powers millions of autogas vehicles worldwide.

With the bi-fuel system, the vehicle starts on gasoline and immediately switches to autogas. This technology provides drivers with flexibility and fleet managers with peace of mind because the vehicle can switch back to gasoline if necessary, so fuel can always be reached.

For fleets interested in vehicles that operate exclusively on propane autogas, we also offer the autogas-dedicated, Prins liquid-injection system. For some fleets, the mono-fuel liquid system is a better fit and ensures maximum fuel cost savings.

But the technology alone isn’t enough. Add our AA+ rated warranty, the ability to transfer conversion systems to new vehicles, and exceptional customer service, and it’s clear why fleets appreciate our complete program.

Vehicle Conversion Centers

The Alliance AutoGas nationwide network includes Certified Conversion Centers with trained technicians who will convert and maintain your autogas vehicles. Alliance AutoGas certified conversion technicians deliver quality-controlled, EPA-certified conversions.

Do you have a larger fleet with skilled in-house technicians? Our conversion experts can train your fleet mechanical team to perform conversions and maintenance for your autogas vehicles.

Conversion Costs

Vehicle conversion requires no upfront cost with Alliance AutoGas. Through competitive financing programs, Alliance delivers autogas conversions for a low monthly payment, which is typically more than offset by fuel cost savings. The total cost of vehicle conversion depends on the type of vehicle being converted (car, van, or truck) and the number of vehicles in your fleet, but a gasoline to autogas conversion costs approximately $5,800 with potential for grants and tax incentives. Fleets that participate in the Alliance financing program often experience an immediate ROI, and those who pay for conversions upfront typically see a return on investment in 12 to 24 months, depending on mileage driven.

Alliance AutoGas offers two excellent financing options: one is custom designed for privately owned vehicle fleets, and the other is designed specifically for public fleets. Both financing options offer favorable terms that, in most cases, enable the fleet to offset their payment through fuel cost savings.
