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.

Unleaded avgas now available at KOXR FBO
Golden West Jet Center at Oxnard Airport (KOXR) is the latest California FBO to offer Swift’s UL94 unleaded aviation gasoline.
Octane ratings: Where did they come from, what do they mean, and why are there so many?
The difference between the RON and the MON is called the fuels sensitivity. Most typical fuels have a sensitivity of around eight numbers. But occasionally there will be a fuel with a 10 to 12 sensitivity, which does not perform as well in the field.
GA advocates successfully fight Washington bill that would have banned 100LL
The original bill, WA HB1554, introduced in January 2023, called for the phased-in restriction on the “selling, distributing, or otherwise making available to consumers” leaded avgas in Washington state starting Jan. 1, 2024.
New math and the unleaded future of general aviation
The search for an unleaded avgas continues, with four fuels still in the running and being evaluated by the FAA. Will all four make it to market? Who will the FAA and the industry get behind as the future of general aviation?
County that banned 100LL invited to be part of project to establish best practices as GA transitions to unleaded fuel
The invitation is part of a memorandum of understanding that the county signed with the FAA on Feb. 7, 2023, that suspended an ongoing FAA investigation into alleged grant violations at the two airports, county officials said, noting the memorandum also “sets forth a framework for participation in the demonstration project.”
Bill introduced in Washington state to ban 100LL
If it becomes law, the bill (WA HB1554) would begin a phased-in restriction on the “selling, distributing, or otherwise making available to consumers” leaded avgas in Washington state starting Jan. 1, 2024. The restrictions would initially be placed on airports in the areas of greatest population, with additional restrictions culminating in a complete ban for the entire state in 2030.
STCs now available for G100UL unleaded avgas
General Aviation Modifications Inc. (GAMI) has opened its online G100UL STC store.
GA advocates submit comments to EPA on proposed 100LL endangerment finding
The coalition urged the EPA, in coordination with the FAA, to “ensure that any final finding and follow-on regulatory actions align with the development and deployment of a viable unleaded avgas alternative.”
