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.
True racing oils (like Honda HP2, Motul 800, Maxima Castor 927, ect.) are not JASO certified, because they don't need to be.
JASO (Japanese Automotive Standards Organization) certifies only oils that will be used in vehicles/motorcycles on public roads in cities, because they need to emit less emissions/smoke and leave less carbon deposits on the piston.
Any 2-stroke oil that will be used in motorcycles on the track or in OPE the woods does't need to cover JASO FC/FD. That is why most OPE oils are FB, including the Stihl oils, and motorcycle racing oils are not rated at all. However, that is not a bad thing because those oils are created to provide the highest protection at high RPM and the emissions and carbon deposits are secondary.
Marine/outboard 2-stroke oils are not JASO certified either.
