Running Mogas/Autofuel in a IO 360 ?

Hi, does anyone have any experience ( not opinion) in running Mogas/Autofuel ( nil ethanol) in a 180hp parallel valve IO 360, I’ve noticed some models ARE on the approved list from Lycoming. Thanks in advance 🐍.
 
The local Indiana/Indianapolis area has Landmark (Farm Bureau?) has 90 octane non alcohol gasoline. I run it in my IO-360 PV 180 hp engine. I retard the timing 2 degrees to get a larger detonation margine, but I have friends who run the full data tag timing (25 degrees) and so far no one has has any problems.

Cautions: do not carry over winter blend into the warmer late spring temperatures. It is alright to carry over summer blend into the winter. I would say I do use 25 or maybe 30% 100LL because thats what is available on XC's. Almost all my flights are LOP mixture. I've run this way for near 1000 hours.
