"Tu Quoque, 100LL?" I clarified with the FAA. See below. How about we try not to distract from the discussion of G100UL effects? We know the experience of 100LL.

Are you saying that the photos in the PAFI lessons learned (page 7) are misleading and not from a candidate fuel, but from 100LL? https://www.faa.gov/sites/faa.gov/files/PAFI_Fuel_Development_Testing_Lessons_Learned.pdf

Hi All, Yes, I’m here on Mooneyspace. Never owned one, but I have a few hours in a friend’s Mooney (which was sold and is the infamous Mooney that later flew through Area 51). Anyways, I’m happy to clarify if something was not clearly stated in the videos. As to not clutter the already long thread, please send me a direct message with your question(s) over the next few days and I’ll try to summarize applicable comments in one response. I just ask that you’ve reviewed the videos (Part 1) (Part 2) to ensure your question is not already covered there. I spent a lot of time compiling the videos and it has been quite frustrating to watch comments on many forums where it is clear people have not watched the videos. I want to reiterate that my initial primary focus was on the effects & compatibility to my personal aircraft. And based on what I learned, I performed more testing and decided to share the results. I do think it is unfair to blame paint jobs being the cause, as 100LL historically seems to do very little, if anything, to painted surfaces. I’ve verified that through the course of my testing. I really want unleaded fuels to work. I’d do the same testing for any other fuel that came to market which I had questions about. Especially so since this is the application of an STC (major alteration) and the A&P/IA has to determine if the modification is compatible with the aircraft. I thought this recent commentary by Darren Pleasance (new AOPA CEO) echoes many of my sentiments. https://www.aopa.org/news-and-media/all-news/2025/january/23/presidents-position-on-unleaded-fuel Michael
