Hello Johnny; I have a Laser 100 that I run on 0%, so I always have some 0% around. I have used that same 0% on my Enya 46's and just about all of my Saito's 30 to 150. It works just fine on all of them. Maybe the idle isn't quite as reliable, and maybe I lose 2 or 3 hundred revs off the top, but if it's the only fuel I brought with me, it works just fine.

I haven't tried it in an OS four stroke, since I don't have one in a plane right now, but I do remember using 0% in one of my OS 90 four strokes, and it worked just fine there.

I would say, buy some ane try it; you're not going to harm anything as long as you don't try to run too lean. I'm pretty sure you'll be pleased with the way it'll run.
