For my leaf blower, I run Saber around a 75/80 to 1 ratio. In my cheap chinese chain saw, it is closer to 32/40 to 1. In both, I use at least 89 octane, non ethanol fuel. Crazy, but I've had a mix of the former still work fine 5+ years later. But I only run that in the leaf blower, not the chainsaw. For the latter I use a more fresh mix.
I bought a Stihl BR380 backpack blower and a Stihl straight shaft trimmer 16 years ago. I have a reasonable property and both my wife and I run them WAY more than a normal household would. We mow 2 to 3 times a week for example.
Amsoil Saber 80:1 with ethanol free fuel. Never had to touch a carb or do anything more than change a spark plug every 1-2 years. No complaints.
I've been running all my 2 cycle OPE on Saber at 80:1 for 5 years now. (with E10 - that's all we have here)
A string trimmer, 2 chain saws (one an antique McCulloch), an old Craftsman snow blower, and a backpack blower. Works great to date.
