I haven't worried too much about octane, 89 is what I've been running. The non ethanol is 91, here. The problem I've been having is the idle ports(beneath the adj screw) kept clogging. Another 289 owner gave me a bottle of sea foam & I topped off with the non ethanol & the problem disappeared. Been running top notch, since. I going to run the tank down & fill up with straight non ethanol, just to see what happens. I can't find a concrete number on what % ethanol is in our fuel here but, I do know the gasoline here stinks(odor), in comparison to what we had in CA. As far as I can remember, it was no different in Oregon or Washington. I do know that CA is running close to 10% ethanol. I'm not a chemist but, I'd sure be interested in what is going on in the fuel here.
