Yes, in every one of my two stroke cars I run it that way. (Actually if I had an old Saab I would.)
Opti 2 is not a synthetic, not that I know what it is, but I know I like it and it is all I use from day one on my two strokes. Chainsaw, too. I used to spend a lot of time breathing in the noxious fumes from a saw and appreciate the clean burning. My motors like the stuff so why shouldn't I?
