G100UL Unleaded Aviation Fuel Now Commercially Available

April 13, 2024

Leaded aviation fuel emissions are responsible for more than 70% of all airborne lead pollution in the U.S. Piston-engine airplanes release 468 tons, nearly one million pounds, of lead into the atmosphere every single year. There is no safe level of lead in a child's blood. Even small amounts can contribute to life long health problems. At long last, there is now an alternative fuel available to finally put an end to the scourge of aviation lead poisoning.

A 4/11/2024 Flying Magazine article, GAMI Says It Has 1 Million Gallons of G100UL, includes a 6 1/2 minute video announcement from George Braly, Co-founder and Head of Engineering at General Aviation Modifications Inc. (GAMI). Braly and GAMI President Tim Roehl have worked for over thirteen years on the development and deployment of this fuel.

Towards this end, GAMI has partnered with an aviation petroleum company, Vitol, in Baton Rouge on the production of G100UL.

A 4/10/2024 Vitol press release on their joint efforts is available below.

In a world first, Vitol has partnered with General Aviation Modifications Inc. to make unleaded 100 octane Aviation Gasoline (AvGas) commercially available.

The first unleaded 100 octane Aviation Gasoline (G100UL AvGas) is approved by the FAA for use in all certificated piston engines.

G100UL AvGas was developed by General Aviation Modifications Inc. and received fleetwide Supplemental Type Certification from the FAA in 2022. As a drop-in replacement for 100LL fuel, aircraft operators are able to use the fuel without any modification to their aircraft. G100UL AvGas can be mixed interchangeably with existing 100LL or approved fuels with less than 100 octane, making its immediate deployment to airports practicable.

Vitol Aviation Inc president John Addison said: "The aviation industry has been looking for commercial unleaded fuel options for a long time. We are delighted to be the first to offer commercially available G100UL AvGas to the entire US aviation market."

Vitol-produced G100UL AvGas is available to any airport or aviation fuel distributor.

For more information contact avgas@vitol.com or your fuel distributor.
