Reid-Hillview Airport of Santa Clara County (KRHV), Watsonville Municipal Airport (KWVI), and Meadows Field Airport (KBFL) in Bakersfield will be the first airports in the country to offer GAMI’s lead-free 100 octane FAA-approved avgas known as G100UL.

STCs now available for G100UL unleaded avgas
General Aviation Modifications Inc. (GAMI) has opened its online G100UL STC store.
Continental gets the lead out
Continental has applied to the FAA to use unleaded aviation gasoline in more than 100 engine models, including select O-200s, IO-360s, O-470s, and IO-470s. As the industry searches for a long-term fuel solution, Continental considers 91UL and 94UL fuel as a transitional step in a long-term strategy to reach a more sustainable aviation, company officials said.
Avgas coalition calls 100LL ban discrimination
“The lack of 100LL fuel at Reid-Hillview has already had a negative impact on humanitarian flights because aircraft are now unable to refuel at the airport.”
The hunt for unleaded avgas ramps up
The hunt for an unleaded replacement for 100LL began in earnest in March 2022 with the first meeting of the Eliminate Aviation Gasoline Lead Emissions (EAGLE) initiative, which brought federal regulators, the oil industry, the aviation industry, and more together to find a solution for the entire general aviation piston aircraft fleet.
Hundreds more engines approved for unleaded avgas
An Oct. 28, 2021, Approved Model List includes an additional 611 engines approved to use GAMI’s new unleaded avgas.
Cessna 172, 182 and 206 approved for lower lead fuels
All three Cessna models are powered by engines manufactured by Lycoming Engines. Lycoming recently approved the use of unleaded and lower-leaded fuels after completion of a series of tests. The fuel is compatible for both new production and legacy Cessna piston aircraft, Textron Aviation officials noted.
A step in the right direction for unleaded fuels
In the roughly 25 years that the GA community has been trying to find an unleaded alternative to 100LL avgas, GAMI’s new unleaded fuel is the first promising step in the right direction.
Fuel returns to KMAO
Marion County Regional Airport (KMAO) in Marion, S.C., has 100LL and Jet-A fuel again after a nearly two-year interruption caused by contaminated tanks.
