Key Takeaways:

The general aviation industry is entering a new era with the transition from leaded 100LL fuel to unleaded alternatives.
GAMI's G100UL received FAA fleetwide certification on September 1, 2022, allowing its use in most piston engines and offering environmental and maintenance benefits.
GAMI has partnered with Avfuel for distribution, with an initial rollout expected in California in early 2023, though a complete transition away from 100LL by 2030 will be a logistical challenge.

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.
