G100UL Avgas Replacement Set to Soon Hit Pumps

Going unleaded results in a cleaner fuel burn, no deposits, and no fouled plugs—all of which leads to reduced maintenance.

Key Takeaways:

  • GAMI's G100UL, a new unleaded aviation fuel, received fleetwide FAA approval on September 1, 2022, marking a significant step towards replacing 100LL.
  • GAMI has partnered with Avfuel for production and distribution, with an initial rollout expected in March or April, starting in California due to local 100LL bans.
  • G100UL offers environmental and maintenance benefits by eliminating lead and other harmful additives, can be stored in existing fuel tanks, but a full industry transition by 2030 is still considered 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.
