Key Takeaways:

The general aviation industry is transitioning from 100LL leaded fuel to unleaded alternatives, with GAMI's G100UL receiving FAA fleet-wide approval on September 1, 2022.
GAMI has partnered with Avfuel for production and distribution, anticipating an initial rollout in California by March or April, followed by a gradual expansion to other regions.
G100UL is a cleaner fuel, free of toxic chemicals like tetraethyl lead, which promises reduced engine maintenance and can be seamlessly integrated with existing infrastructure by being stored in the same tanks as legacy avgas.

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.
