Key Takeaways:

General Aviation Modifications, Inc. (GAMI) received fleet-wide FAA approval (STC) for its G100UL as a viable unleaded replacement for 100LL, marking a new era for cleaner aviation fuel.
GAMI has partnered with Avfuel for production and distribution, with a phased rollout planned to start in California around March or April, gradually expanding to other regions.
G100UL offers a cleaner fuel burn and reduced engine maintenance due to the absence of lead and other toxic additives, while also being compatible with existing fuel infrastructure.

We stand at the dawn of a new age for general aviation. For years, the industry standard fuel, 100LL, dominated the market. Now a new player is entering the game, and they bring the hopes of a cleaner world with them.

Over a decade in the making and countless hours of research, testing, and design bring us to this point in history. After a prolonged silence, the FAA finally issued the decree. Change has come at last.
