No, G100UL is still going through the FAA approval process. But it’s been approved for many specific engines already, but the majority still aren’t allowed to use it. For a full FAA approval we could be waiting another 6-9 years.
The Next big problem is availability, which will only come with time. There are only a few airfields around that stock the fuel. (And from what I can tell… none that are here in Australia)
Yep, and the FAA is taking it’s sweet time to approve a new unleaded fuel for general aviation that shows a lot of promise called G100UL. It’s estimated it could take another 6-9 years. Otherwise it’s currently only approved for specific planes and not available at most airports and aerodromes.
