avgas fueling 100LL

Unleaded AVgas Holdup

I just received my October 2024 issue of Aviation Consumer and went straight to Rick Durden’s unleaded avgas update article. I operate an U.S.-registered Cessna R172K with a Continental IO-360-KB, based in Switzerland, and have been an Aviation Consumer subscriber since the 1990s.

I am hugely frustrated by how little the normally very environmental-conscious authorities—and even aviation groups such as AOPA— have not jumped on the G100UL bandwagon and are just waiting for G100UL to be generally available in the U.S. I have purchased the G100UL STC as a demonstration of support since there is no likelihood of being able to put it in my tank in the near future. GAMI is focusing entirely on the U.S. market even if the path of least resistance to getting G100UL into aircraft in Europe might be more resource efficient.
