Alliance AutoGas

In 2018, Todd Smith, City Administrator for the Town of Greeneville, TN, wanted to reduce the town’s expenses as well as their impact on the environment. Smith started to research the potential benefits of adding an autogas program to the town’s fleet, and found that by working with Alliance AutoGas (AAG), they could purchase fuel at a fixed rate, have reduced maintenance requirements, and the ability to reduce the town’s carbon footprint. “After confirming those key benefits, we knew this was a program to implement,” said Smith.

The Town of Greeneville started with converting three of their Law Enforcement Ford Explorers. One benefit of the converted police vehicles that Smith soon found was having a bi-fuel engine. An autogas bi-fuel vehicle is a conventional gasoline vehicle that can run on both autogas and gasoline. The primary advantage of a bi-fuel system over a dedicated “monofuel” system is its elimination of range anxiety when compared to other alternative fuel vehicles. “In addition to upfront benefits found in autogas, having an additional fuel increases the department’s loiter time in our vehicles for emergencies,” according to Smith.

After seeing the success with its three initial autogas vehicles, the Town of Greeneville expanded its autogas program with AAG. The town currently has 18 converted autogas vehicles for the local police department, which includes 13 Ford Law Enforcement Sedans, and five Ford Law Enforcement Explorers. As with many of AAG’s customers, the Town of Greeneville decided to invest in its own autogas refueling station. “AAG was able to quickly deliver and install a propane vehicle refueling station for the town that is as similar to operate as going to your regular gasoline station,” says David Kennedy, Director of Autogas Design at Alliance AutoGas. “The Town of Greeneville officers can easily drive up, activate, and fill their vehicles with propane at their very own convenient AAG propane station.” When speaking on the refueling infrastructure, Smith added, “With the new infrastructure, our officers can refuel their vehicles quickly while being able to easily respond to calls. It makes refueling very convenient for our department.”

The Alliance AutoGas National Network also includes AAG Certified Service and Installation centers. Kyker’s Extreme Automotive, which is owned and operated by Dale and Lisa Kyker, has served the Greeneville area since 1982, and has a long history of servicing the town of Greeneville’s vehicles. As such, it was only natural that Kyker’s became a certified Service and Installation Center so that they were able to continue maintaining the town’s vehicles. “We actually started propane conversions in 1988 for a local fleet, and one of those trucks is still in use today,” said Dale Kyker. “Working with AAG has been simple, straight-forward, and the training was top notch. The AAG conversion systems are relatively flawless and very well designed. We believe propane is a great alternative fuel with less of a carbon footprint than gasoline. It can save the taxpayer money and increase our officer’s ability to stay on the scene, which makes it a win for everyone involved.”

In times of emergencies, like the current fight against COVID-19, fuel uncertainty is among many concerns for fleets across the country. Propane autogas is produced domestically, which provides a reliable fuel source for all essential employees who are utilizing the alternative fuel. Autogas gives fleets independence by not having to rely on foreign fuel and provides the ability to focus on whatever is needed out of a particular fleet during a crisis. “Having an additional fuel source helps maintain the town’s ability to provide critical services to the residents of Greeneville in times of shortages and emergencies,” says Todd Smith.

Alliance AutoGas member Blossman Gas is the refueling partner in this project. Scott Prewitt, Regional Vice President for Blossman Gas says, “Blossman is proud to have the opportunity to serve the town and this police department. It shows how much their leadership cares about the residents they serve. Autogas gives fleets a peace of mind for the department in knowing they have a sustainable domestic fuel source.” To date, the Town of Greeneville has used 18,500 gallons of autogas, which according to EPA calculations displaces 566 barrels of oil and 448 short tons of greenhouse gas emissions. 

Happy Fox, an Alternative Fuel Consultant for AAG says, “The Town of Greeneville has an outstanding team that is committed to serving the local community. They have been great to work with in regards to their autogas program.” When discussing the future of the propane autogas program, Todd Smith added, “Propane now is an option to consider when looking at alternative fuel sources across the Town of Greeneville. We are currently discussing being able to expand our program for local school buses among other departments.” 


Green’s Blue Flame Gas Company is leading by example in the propane industry. In October of 2019, the company finished converting the last of its service and delivery vehicle fleet to operate using propane autogas. This now means that their entire fleet, 100% of their applicable vehicles, are propane equipped. Green’s Blue Flame, one of the first partners of Alliance AutoGas (AAG) in 2010, has been under continuous ownership and operation by the Green family who started the business in 1967.

President of Green’s Blue Flame Gas Company, Joe Green says, “I met Randy Doyle [former CFO] of Blossman Gas [founding company of AAG] back in 2009 through [NPGA] benchmarking. Randy told me about AAG and asked if I was interested. After I said I was, Stuart Weidie called me and I soon found out that we had a lot of common interests. We wanted to run everything we could on propane and make propane more accessible to our customers, and I knew AAG could contribute to that goal.” When speaking upon the impact Green’s Blue Flame has made on the propane industry, Stuart Weidie, President of AAG added, “Joe and Brian Green have been leaders in the US autogas industry for many years. We are honored that they are a major contributor to the AAG network and have set a fine example by deploying autogas in their own fleet.”

Since Bill Green started Green’s Blue Flame Gas Company back in the 1960s, the family business has always utilized propane in whatever way possible. Brian Green, Business Development Manager for Green’s Blue Flame says, “The technology has changed significantly over the years but the constant for our company has been the mentality of doing what is necessary to convert our vehicles and keep them running on propane.” Shawn Hicks, Service Manager for Green’s Blue Flame, has been with the company for almost 40 years and has contributed largely to the success of their autogas program. “Having someone in-house that has the ability to diagnose and repair anything propane related has been key in enabling the company to achieve a 100% propane fleet, not including our propane transport,” says Green.

The entire world is facing both personal and professional challenges in the fight against COVID-19. While social distancing and staying at home are key parts of winning this fight, many businesses and organizations deemed essential must continue to operate. When speaking upon the family’s business, Brian Green says, “The propane industry is working in the background to make sure homes and other essential businesses continue to operate during this difficult time. As a primarily commercial-focused propane service provider, we have many customers critical to the supply chain needed to support households and essential infrastructure. The most notable is a local food bank that distributes food to those that need it.” Garrett Green, Operations Manager for Green’s Blue Flame states, “We made changes to our delivery and invoicing process to provide the safest environment possible for our employees and customers while maintaining a quality service.” Stuart Weidie from AAG adds, “The United States should not allow its transportation sector to be subject to another country’s production of goods and materials. Instead, we should all join the movement to use a domestically produced transportation fuel, propane autogas, to ensure our national security and clean the air.”

This past year, Green’s Blue Flame was able to secure about $65,000 through the Texas Emissions Reduction Plan (TERP) to convert their fleet to the domestic fuel. The TERP program provides financial incentives to eligible individuals, businesses, or local governments to reduce emissions from polluting vehicles and equipment. “Our state is fortunate to have a program like TERP, which provides incentives to fleets who want to utilize a clean-burning fuel such as propane,” says Brian Green.

Green’s Blue Flame has 18 total vehicles in their service and delivery fleet, ranging from bobtail trucks to light-duty services trucks. Fuel savings are adding up quickly; the company is currently saving 60% by using propane in their bobtail trucks as opposed to diesel and saving 50% by utilizing propane in their light-duty vehicles. Green’s Blue Flame is also pleased to see savings on their overall vehicle maintenance. For example, regulations require diesel-powered vehicles to use diesel emissions fluid (DEF) for daily operation to help reduce particulate matter and nitrogen oxide (NOx). Propane autogas burns clean and does not require additional fluids like DEF, which eliminates the expense entirely.

AAG is thrilled to have a Partner like Green’s Blue Flame lead by example in the propane industry. Jessica Johnson, Partner and Projects Liaison for AAG says, “Green’s Blue Flame Gas Company exemplifies how a propane company should aim to do business in today’s industry. We have enjoyed working with them over the years and hope our other partners will strive to convert their fleets to 100% autogas as well, now that they see it can be done.” When speaking on Green’s Blue Flame recent accomplishment, Brian Green added, “Having a fleet where we run everything on propane shows we fully believe in propane as a fleet fuel. By having 100% of our fleet run on autogas, it shows our customers how invested we are in propane.”


A Letter from Alliance AutoGas President

March 25, 2020

President of Alliance AutoGas Head shot Stuart Weidie

Our country is going through one of the most challenging periods in its history. There is no doubt that the health crisis is impacting individuals and families across the United States. People are worried about getting sick or losing their job, and unfortunately many already have. My hope and prayer is that this crisis will diminish in the coming months and some sense of normalcy will return. 

There is something instructive we should take away from this crisis. Our country should not be dependent on other countries for essential goods and services that are needed for the citizens of our country.

The economic impact is being felt by both individuals and businesses. Layoffs and furloughs have been experienced by a great number of people, through no fault of their own. Companies have lost revenue as a result of lost or reduced demand. The resilience of our citizens and our strongest companies will prevail in the end, but that does not diminish the impact right now. 

Economic Efficiency and National Security

One of the lessons we should consider is the balance between economic efficiency and national security. Economists who advocate that goods and services should be produced in the countries with the least amount of cost and shipped globally only consider economic efficiency. The current crisis illustrates the problem with taking this approach to the exclusion of other factors such as national security.

It has been reported that other countries produce 97% of all antibiotics and 80% of active ingredients used to make medications here in the United States – including 45% of all insulin for people being treated for diabetes. Industrial capacity in the United States has been falling for more than 4 decades, which results in the loss of good paying jobs right here at home. Do we think this should continue?

Domestic Energy

The advocates for the so called zero emission battery electric vehicle (BEV) should take note. First, emissions are still produced by the production of electricity. Of greater concern is that China controls over 85% of the global supply of cobalt and nearly 50% of the lithium supply – two key materials in batteries. Like medications that affect the health of our citizens, the United States should not allow its transportation sector to be subject to another country’s production of goods and materials.

Instead, we should all join the movement to use a domestically produced transportation fuel, propane autogas, to ensure our national security AND clean the air. Autogas costs less, reduces emissions dramatically and enhances the national security of our country.

Please unite with me in the movement to make domestically produced autogas prevalent in the United States. With over 28 million autogas vehicles around the world, it is proven and ready right here, right now.


At Alliance AutoGas, safety is our highest priority. With that in mind, we are taking extra measures to keep our communities safe and limit the spread of COVID-19.

As a company, we will continue to perform all gas delivery services to our customers, as we understand the essential nature of our energy source to the homes and businesses we serve.  We will also continue to fulfill autogas kits and parts sales.

We will only be entering buildings and enclosed structures on an emergency basis or to repair essential products.  Should we be required to enter a building, we have implemented sanitary practices and guidelines as prescribed by CDC and OSHA.

The following additional steps are being taken to ensure the utmost safety:

  • We are sanitizing company vehicles prior to the start of each shift. This includes, but is not limited to, a wipe-down of vehicle seats, dashboards, door handles, and steering wheels.
  • All workspaces are being cleaned before and after each use. This includes, but not limited to, all AAG equipment, company computers, and phones.
  • AAG has established a set of protocols to ensure that any of our employees who are potentially infected stay at home.
  • All AAG employees are following strict guidelines set forth by the CDC and WHO on washing hands and cleanliness.

For more information about COVID-19, you can visit the CDC site HERE.

We will continue to monitor the situation and update our company policies accordingly. Thank you for trusting us to deliver your energy needs.

2019 was an exciting and historically significant year for Alliance AutoGas (AAG). By continuing to lead the autogas industry in the research and development of after-market vehicle conversion equipment, AAG obtained 37 Certificates of Conformity from the Environmental Protection Agency (EPA), which cover 167 different vehicle types; proving that as technology continues to evolve, propane autogas remains a reliable alternative fuel source for fleets. The Alliance AutoGas Nationwide Network currently supports 417 autogas fleets, and in 2019 alone, those fleets utilized 16,686,297 gallons of autogas, which displaced 15,123,000 gallons of gasoline, and 345,065 barrels of foreign oil. By using over 16 million gallons of autogas, drivers reduced 312,314 short tons of Greenhouse Gas Emissions, which is comparable to the CO2 offset by 4.7 million trees.

City of Roanoke, VA received Honorable Mention for their sustainability efforts at the Sustainable Fleet Technology Conference.

By converting their vehicles to autogas, AAG customers are bettering their communities by reducing harmful emissions and contributing to cleaner air. In August, at the Sustainable Fleet Technology Conference and Expo, held in Durham, NC, the 2019 “Green Fleet Awards” were announced. Five of the nationally awarded fleets were Alliance AutoGas customers, including DeKalb County, GA ranked #10, Cobb County, GA ranked #27, the City of Raleigh, NC ranked #33, Prince George’s County, MD ranked #43, and the City of Roanoke, VA received an Honorable Mention. These award rankings were based on multiple factors including fuel emissions, fleet composition, supporting programs, and fleet utilization.

Richard Hilmer, Fleet Manager for Prince George’s County, recalled, “Our county has put a lot of time and resources into running an efficient, eco-friendly fleet. It is exciting to be awarded for those efforts. We consider our county to be a leader in best practices for the fleet community.” Davidson County Transportation System, another AAG customer, received the Propane Autogas Fleet Award for their sustainability efforts at BusCon, the largest bus show in North America, which took place September 23rd – 25th in Indianapolis, IN. The Propane Education & Research Council (PERC) presented the ninth-annual Propane Autogas Fleet Award at the show. Previous winners of the award include AAG customers Spartanburg Regional Healthcare System in 2018, and NET Trans in 2017.

2019 also marked a significant milestone for Alliance AutoGas, as the company received its first patent for the development of the LPG Evacuation Pump. When working with an autogas, or a Liquid Propane Gas (LPG) system, all fuel must be emptied from the tank in order to perform internal repairs and service. The LPG Evacuation Pump was designed with service technicians in mind, who now can evacuate autogas tanks in a safe and efficient manner. “Customers were coming to us and asking for help servicing their autogas vehicles,” said David Kennedy, Director of Autogas Design for Alliance AutoGas. “After listening to their needs, we developed a quick and easy way to remove propane and prepare the vehicles for service. Receiving this patent is exciting for us, and shows a serious commitment to the alternative fuels industry, specifically the autogas segment, where we see continued growth in the future.” Jim Bunsey, of AAG Partner Superior Energy Systems, a distributor of the evacuation pump agrees, “We have seen demand rise for a safe and effective way to remove propane from autogas vehicles and school buses running on propane. This system does just that with no engine, electricity or switching of hoses. It is a perfect service and maintenance solution for autogas fleets.”

As the autogas segment continues to grow, AAG has also been committed to growing its National Network of service and installation centers by adding 23 new locations in 2019. To date, 127 locations nationwide are trained and certified to maintain and install the Alliance AutoGas Engineered system. By continuing to grow its Conversion and Installation Center Network, AAG is assuring growth of the autogas movement for years to come, and adding to their already significant foundation of support for more than 200,000 autogas vehicles already on the road.

When describing AAG’s biggest technological advancement of 2019, Ed Hoffman, President of Blossman Services (the distribution partner for Alliance AutoGas systems) says, “The Prins eVP500 electronic variable pressure reducer was the most impactful product introduction this year. The addition of this component to our conversion systems offers the customer a compact design, superior performance, and worry-free maintenance.” Stuart Weidie, President of Alliance AutoGas adds, “As we go into 2020 I am proud of the progress we have made on providing advanced conversion options for a wide variety of advanced engine technologies, including direct injected engines. We continue to distinguish ourselves from the competition every day in this regard.” 

Alliance AutoGas at the GA Pest Conference

Alliance AutoGas (AAG) participated at the Georgia Pest Control Winter Conference on January 7th – 9th in Athens, GA. Nationwide, Georgia’s pest management industry is regarded as one of the most professional and advanced in the country. This conference brought in over 600 attendees who learned about the latest advancements in products, services, and technologies related to pest management.

AAG presented their aftermarket alternative fuel technology in a Law Enforcement Edition Ford Explorer Interceptor, and a Chevrolet Silverado, both equipped with the Alliance engineered bi-fuel system. Butch Cox, Alternative Fuel Consultant for AAG said, “We were pleased to see the awareness generated for propane autogas vehicles during the conference. I am glad we had the ability to show attendees first-hand our technology in a vehicle. It goes a long way in explaining our process.”

Cox also discussed that attendees were interested to learn the details on how our bi-fuel system works, by allowing the vehicle’s engine to start by using gasoline, then transition to autogas with the push of a button.  The primary advantage of a bi-fuel system over a dedicated “monofuel” autogas system is its elimination of range anxiety when compared to other alternative fuel vehicles. In the event that a driver has traveled out of range of an autogas refueling station, they can simply switch over to gasoline until they are able to refuel.


FiveTales Racing earned a strong finish in their last race of the 2019 season at Atlanta Motorsports Park. The 1991 Mazda MX-5 Miata finished 10th out of a field of 49 in the AMP’d Up Duals race on October 26th. FiveTales Racing represents four team members from Alliance AutoGas and Blossman Gas who decided to take teamwork one step further. Jake Weidie, Scott Prewitt, Steve McCoy, and David Kennedy decided they would apply their talents and experience to champ car racing five years ago, and have enjoyed the high speeds ever since.

Jake Weidie, race team member, recalls: “Our last race of 2019, it had rain before and during the race, which actually put us in a good position. Rain tends to even out the race cars in our series. It gives our team the opportunity to be more aggressive while others need to be more careful. I am glad we were able to finish 2019 on a high note.”

The race team has big plans for 2020, which includes converting the car to an Alliance AutoGas engineered bi-fuel system. Having a bi-fuel system means that the car would have the capability of running on clean-burning propane autogas as well as gasoline. “We look forward to seeing how the car handles a bi-fuel system. It will be exciting to test it out throughout the season,” says Weidie.

Everdure by Heston Blumenthal, a valued partner of Blossman Gas, will be sponsoring the race team for a second year in a row along with Alliance AutoGas and Blossman Gas. FiveTales Racing’s first two races of 2020 will be 12 Hours of VIR (South) on March 7th at Virginia International Raceway and 14 Hours of Charlotte on April 25th at Charlotte Motor Speedway. Race team member David Kennedy adds, “Our car showed a tremendous amount speed throughout 2019. Everybody on the team looks forward to building off our success in 2020 and converting the car to an Alliance AutoGas engineered bi-fuel system.”
