Key Takeaways:

GAMI's G100UL unleaded aviation fuel received fleetwide FAA approval on September 1, 2022, marking a major step towards replacing 100LL in general aviation.
Production and distribution, in partnership with Avfuel, are ramping up, with an initial rollout expected in California by March or April, followed by a gradual expansion.
G100UL offers significant benefits, including a cleaner burn, reduced engine maintenance due to the absence of lead and toxic additives, and compatibility with existing fuel infrastructure.
The transition is crucial given increasing demand for general aviation, potential restrictions on leaded fuel, and the EU's move to ban tetraethyl lead.

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.
