Fri Dec 20 2024
December 20, 2024, G100UL high octane unleaded avgas arrives in Mississippi!
Tupelo, MS — General Aviation Modifications, Inc., is pleased to announce the deployment and sale of our G100UL® High Octane, Unleaded Avgas by Tupelo Aviation Unlimited at the Tupelo Regional Airport (KTUP) in Mississippi. This represents the first availability of G100UL outside of the State of California!
We congratulate Tupelo Aviation for their foresight and initiative in supporting the transition of the general aviation industry to unleaded aviation gasoline. GAMI’s G100UL is the only high-octane, unleaded avgas approved by the FAA for use by all spark-ignition piston engines and all of the airplanes that use those engines.
Tupelo Aviation and the Tupelo Regional Airport can now serve as a preferential destination for aviators seeking to remove lead deposits from their engines and support the safe and orderly transition to unleaded avgas and a sustainable future for all of General Aviation.
For more information please see the official AMS press release.

RE: Cirrus Service Advisory SA24-14
Contrary to the recently released Cirrus Service Advisory SA24-14 the use of G100UL Avgas is fully compatible with both PSD & PTE sealants when either of those sealants are properly applied during the production of the wings and fuel bays of Cirrus SR22 aircraft.
