Wrong section.
Anyway, a lot of us are switching to E85, but I do realize it’s no where close to you.
However, the AVGAS that you speak of is an EXCELLENT fuel. “formulated for low oxygen, high altitude” is garbage. It’ll take the place of any ~100 octane ‘race gas’ just fine, I’ve used it off and on for years.
EDIT-a quick search shows E85 not too far from you (under 50 miles).
:haha
Yeah, I’d def want a race fuel in something that Flatline t00ned for pump gas, just to be ‘safe’.
