The problems are a lack of leadership to subsidize it at the pump and a timeline to ban it. G100UL currently costs 70% more than 100LL. A certification process is required to fuel with G100UL (no engine changes are required, but it's the aviation industry and it creates an orderly transition process with more paperwork) and it's currently difficult to find. If you want to get G100UL now, look for general aviation flight schools. https://stc.g100ul.com https://stc.g100ul.com
