I’ve seen conflicting reports of running a ULPower on 100LL. Mogas is hard to find out west and where it is available it is 91 AKI and would still need to be mixed with 100LL for their higher compression engines.
This guy suggests running 50/50 mix but his photos from 100% LL are pretty scary. Why No Avgas?
I don’t look forward to carting 20 gallons of mogas to the airport every time I want to go flying. I think the G100UL will pick up speed fast, but that’s a guess.
This seems to help but it’s all anecdotal stories as far as I can find and it seem to be the lesser of two evils rather than a cure: Decalin RunUp Fuel Additive | Decalin Chemicals
