I have bulk 87 octane here which is non alcohol but no one nearby has 89 or 93 octane in anything but 10%.I know Stihl and others recommend 89 but to buy it without ethanol,I'd have to drive 20 to 30 miles one way.
Am I risking anything beside performance using my 87 and Stihl Ultra ? Even if I get several cans I'd be concerned about stale fuel even though the synthetic mix has a stabilizer.
