High octane non ethanol fuel mixed with a good quality 2 cycle oil. Mix in small quantity's. Don't mix large amounts and let it sit around. Use it up. I used to mix 2.5 gallons at a time when I was falling but these days I only mix up a gallon at a time unless I have a really big job to do. I still mix several 1 gallon cans.
Still running a 1985 era Husky 266 as a backup to the backup. Starts on 4 -5 pulls when cold.
For the occasional user I would look into the pre packaged fuel such as Tru Fuel etc.
Bought a new Husky 550 with the auto tune. Was skeptical at first but that saw is a screamer. Use it for thinning projects instead of lugging around a 372.
