After extensive testing (all of 5 minutes), I think the answer is maybe for some, but not if I didn't absolutely have to.
I have 4 different 2 stroke oils in the garage just now and out of them all, Valvoline Durablend is the closest in look, smell & viscosity to the 10w30 I used as a benchmark, probably a little thicker.
Silkolene Super 2 injector, Castrol Actevo and Shell VSX just didn't feel comparable: they were noticeably thinner and didn't smell like oil at all. However, the Motul synthetic I use in the 990 smells even less like oil, so that's not a huge indicator.
Given there's no info about additives (other than Valvoline mentions a salt), I'd be wary of using something that's designed to be diluted & burnt.
