My take is that it鈥檚 a good start and important step towards fully de-leading the fleet fuel. There was a good article on AVweb breaking down the difference between the STC and ASTM approaches and the work that still need to be done:

If you own a plane, do you intend to buy the GAMI STC for it?
Do you have access to G100UL at your airport or in your area?
I hope it gets adopted widely. It would be great if there was a better process that was feasible. As far as buying the STC, I will probably push for my club to get it once it鈥檚 available in my state, but it may be a challenge with some of my co-owners. The real path to the STC for me is likely when I鈥檓 flying to a destination where it鈥檚 the only option. That may happen for me and one of my other co-owners soon with trips to the west coast.
