Emerging Trends in Piston-Engine Aircraft Gasoline (AvGas) Sales Market

Piston-engine aircraft gasoline (AvGas) sales are expected to evolve from a legacy fuel market to a transition market between 2025 and 2027. General aviation demand will continue to influence the market. However, the lead reduction, refinery limitations, and blending challenges will change purchasing dynamics. Lucintel anticipates that operators, airports, and fuel suppliers will focus on certified alternatives that do not negatively impact existing fleet operations.

• Sustainability: The FAA's EAGLE initiative aims for complete availability of unleaded avgas by 2030. With more than 220,000 piston aircraft still in service in the United States, investments will shift to low-lead and unleaded formulations in the next 3 to 5 years, as GAMI's G100UL and Swift Fuels' 100R will help the industry move away from tetraethyl lead.
• Regional Supply-chain Diversification: Due to refinery closures and reliance on specialized additives, suppliers prefer to hold larger inventories and source from several terminals. Before the pandemic, the United States used approximately 200 million gallons of avgas each year, which led to several airports experiencing localized shortages. The resiliency of the supply will affect the terms of contracts as well as the pricing of fuel at airports.
• Premiumization: 100LL continues to be the predominant avgas grade. Due to the operational demands of aging piston aircraft, suppliers who offer superior quality along with technical services maintain profitability, even in a market of constrained growth.
• Digital Distribution: From 2025 to 2027, many airport systems will begin to digitize records of transactions, and several fixed-base operators will implement the digital fuel management programs, online ordering, and card-based purchasing. Digital production will improve the accuracy of demand forecasting and minimize stockout chances. It will also allow small regional suppliers to be more competitive.
• Fleet Efficiency: Several training schools and independent operators have begun to measure the cost in burned fuel and the cost of the maintenance of greater thermal efficiency of the engines on the newer piston aircraft. Concerning the U.S. airport prices in 2025 of >$6 per gallon of avgas, the focus will be efficiency, and also the use of alternative fuels.

The market will not vanish, but the current focus will be on other aspects of the market, such as the economics of lead reduction or digital purchasing systems. The current suppliers will have the edge in the market due to their advanced knowledge of the systems. However, the producers of fuel that maintain quality, approve needed changes, and assist the airports in the conversion, will be the major players of the market until 2030.

Recent Developments in the Piston-Engine Aircraft Gasoline (AvGas) Sales Market

The market for piston-engine aircraft gasoline (AvGas) is entering a period of transition as opposed to a volume boom. From 2025 to 2027 demand will continue to be associated with flight school activity and general aviation, while unleaded approvals, refinery economics, and distribution will reshape how suppliers position themselves. Lucintel believes the market will first adopt technologies before individual consumption grows.

• Unleaded Fuel Approvals: The FAA's approval of G100UL for the piston fleet in July 2024 provided operators with an alternative to 100LL. Wider adoption during 2025-2027 will remove lead-related restrictions and shift purchases towards approved unleaded grades.
• Fuel Development Partnerships: Swift Fuels and the aviation stakeholders have continued to advance 100R as a 100-octane unleaded replacement. ASTM's work on 100R for 2025 will be a positive step to standardization, as 100LL replacement will require airports to install one unleaded grade instead of segregated 100LL.
• Airport Infrastructure: Many airports in the United States are currently improving their storage, dispensing, and labeling systems to offer multiple options of AvGas, with funding through the FAA's $1 billion grant program for Airport improvements for 2022-2026.
• Pressure on Leaded AvGas: The endangerment finding for leaded avgas by the EPA in October 2023 has spurred industry and government planning for 2025. During this year the procurement, compliance, and cost of a nationwide replacement will be dictated by the work currently being done under the EAGLE initiative.
• Refinery and Supply-chain Discipline: U.S. producers have come to terms with the economics for specialty-grade fuels while demand from the general aviation sector has remained muted. As an example, Shell's 2024 scheduled withdrawal from numerous activities related to aviation fuel demonstrates rationalization of their portfolio. In the next five years, it is probable that the number of suppliers willing and able to fulfill contracts will decrease. This could widen regional pricing disparities and further enhance the value of stable distribution contracts.

An increase in aircraft numbers alone will not have significant market disruption. This is especially true when one factors in the level of certification, readiness of airports to operate on unleaded fuel, and reliable sources of the different grades of aviation fuel that will be offered. Market share for an alternative fuel will be adopted when it is as good as or better than the current 100LL based on performance and price. Approved suppliers of alternative fuels who have airport access and relationships with fuel distributors will benefit, whereas smaller airports may experience a lengthy fuel transition and a significant financial outlay to achieve it.

Strategic Growth Opportunities in the Piston-Engine Aircraft Gasoline (AvGas) Sales Market

The commercial openings for piston-engine aircraft gasoline (avgas) sales are increasing as airports prepare for lead elimination, operators search for dependable alternatives, and regulators tighten expectations for emissions. Based upon their market viewpoint, Lucintel anticipates that between 2024 and 2026 a greater value will be placed on certified formulations and localized supplies and on services that aid in the conversion of a fleet.

• Unleaded Fuel Conversion: When the 100LL fuel is replaced by 94UL or 100UL fuel, the approved substitutions may be utilized in certain aircraft. The January 2025 FAA statistics placed over 16,000 models of aircraft under approved unleaded pathways. This will increase as owners become compliant while also decreasing the maintenance associated with lead deposits.
• Premium High-performance AvGas: Specialty fuels in the range of higher octane and vapor pressure may be a justifiable cost for turbocharged engines. In March 2025, there was a considerable high-performance piston aircraft niche over 300 horsepower in the U.S., where reliability was valued more than small price differences. Premium AvGas will gain market share primarily with the training, charter, and utility operators.
• Airport-based Distribution: Regional fuel networks would capture sales where major suppliers have low storage and delivery density. In February 2025, the United States had over 5,000 public use airports, providing a large refill market beyond major facilities. Local inventory, contract delivery, and mobile refueling services will determine customer retention over the next five years.
• Sustainable Blending Pathways: The use of lower carbon blended fuel or certified blending may allow flight schools and corporate owners facing reporting obligations to target carbon emissions. The second phase of ICAO's CORSIA initiative in May 2025 included over 120 participating countries. Suppliers of AvGas who can verify lifetime data may continue to enter into new contracts before complete fleet replacement.
• Digital Fleet Services: In the provision of fuel, companies can provide a recurring source of revenue through aviation eligibility tools, tracking consumption, and conversion record keeping. In April 2025, the FAA registration records exceeded 300,000 civil aircraft, providing a major installed base for software companies. Digital services will eliminate some of the uncertainty surrounding the selection of fuel and will enhance repeat purchase by dispersed operators.

AvGas suppliers should consider the shifting of 100LL as a substantial change in their portfolio, rather than the introduction of a single fuel. The providers of approved fuel formulations who can combine reliable airport distribution with compliance data and conversion services will have the greatest success. Although turbine fuel demand is much greater, the presence of dispersed operators provides significant opportunities for entrepreneurs who can reduce the uncertainty of the operations and ensure piston fleets remain operational throughout the next cycles and subsequent regulatory changes.

Piston-Engine Aircraft Gasoline (AvGas) Sales Market Drivers and Challenges

Piston-engine aircraft gasoline (AvGas) sales market growth is dictated by customer demand, aviation activities, fuel technology, environmental objectives, infrastructure, and regulations. Change and challenges relative to lead elimination, supply security, price volatility and the transition of the fleet will influence the use of both conventional and unleaded Avgas for general aviation for some years to come.

The factors responsible for driving this market include:

• Utilization of Fleet and Flight Activity: In the United States, the FAA has forecasted that by January 2025 general aviation activities will exceed 25.5 million hours, an increase in private flying, flying for training and agricultural or recreational flying will increase recurrent avgas usage. Higher fleet utilization leads directly to increased fuel purchases and continuation of training will create an intermediate term avgas demand.
• Development of Unleaded Fuel: The preference of both users and regulators is to replace 100LL with alternatives that have no or reduced lead content. The FAA granted approval of Swift Fuels UL94 unleaded avgas for use in certified aircraft in 2025 (March 2025). Continued certification and testing and airport availability will result in sales unleaded fuel.
• Regulatory and Environmental Support: Emission mitigation regulations drive research, certification, and infrastructure development for lower lead and unleaded aviation gasoline. The ReFuelEU Aviation regulation implemented a 2% sustainable aviation fuel mandate for targeted flights in January 2025, even though it primarily concerns turbine aviation. Other environmental policies will prompt better control of piston-engine fuels over the next three to five years.
• Airport Infrastructure Enhancements: The ease of purchasing fuel and reducing the operational uncertainty of aircraft operators is enhanced by the reliability of fuel availability at airports. Of the more than 5,000 public-use airports available to general aviation in the U.S. in 2025, economic growth and increasing employment opportunities will prompt private investments toward storage tanks, dispensing systems, quality control, and the infrastructure of both 100LL and unleaded avgas.
• Product Innovation and Cost Optimization: The development of aviation fuels will benefit from improvements in the performance of unleaded fuels in piston engines and a reduction in compliance and operational costs. New procedures for aviation fuels specifications associated with piston-engine avgas were approved in 2025.

The challenges facing this market include:

• Lead Replacement and Certification Difficulties: Eliminating 100LL requires significant testing due to the differences in piston engines, valves, seals, designs, and operating conditions of aircraft. The FAA's EAGLE initiative aims for a national unleaded avgas transition by 2030. Increased lead times, incomplete compatibility of fleets, and the requirement to use multiple fuel grades will consequently test the commitment of distributors and aircraft owners.
• Price Volatility and Low Production Rate: Avgas has a higher price compared to automotive gasoline because of special refining, additives, certification and transportation as well as low production rates. Throughout 2025, the average price for avgas at most airports in the U.S. was above $6 per gallon (June 2025). Volatility in crude oil pricing, refinery constraints, and demand imbalances negatively impact the decisions of operators to invest in new, modern fuel systems.
• Supply Chain and Airport Availability: Lower available airports may have challenges with the reliability of supply, limited storage, and the ability to support multiple grades of avgas. The aviation industry continued to deal with disruptions to the supply chain for fuel logistics during the 2025 refinery maintenance and transportation constraints in March 2025. Within the next 3 to 5 years, poor distribution will likely cause regional fuel shortages, increases in price, and a reluctance from operators to switch to recently certified fuels.

The demand for gasoline for piston engine aircraft will be sustained by flight training, private aviation, airport activity, and continued operation of aircraft. Lead elimination and certifications, production economics and distribution will be important to how this market is ultimately defined. There is a long, sustained demand for new technology, long lead, unleaded fuels, and investments in this new infrastructure. The technology for pricing and availability of new fuels is slow to come. Competitive edge will be gained by companies that secure reliable supply and broad aircraft compatibility, coupled with approvals. The market will show a long, gradual shift from currently available to new, more diverse, clean fuels.
