Stop in for a cup of coffee

I just found out my chainsaw "prefers" non ethanol 89 octane, will have to see if I can find in town, been using 87. Neighbor who works at ACE and has a lot of Stihl showed me his can of 93 Octane Stihl gas, holy cow, over $20 a gallon!
A lot of places sell premixed gas. Haven’t gone that route, but maybe a way to solve ethanol issue. I go through way too much gas in th mower for that. Just thinking for the saw. Maybe string trimmer. But so far those havent been a problem.
