I don't put much stock in premium 2 stroke oils, they are all held to a standard in order to get the tcw-3 rating. And the blends are all pretty much the same
I run penzoil premium 2-stroke in my vmax, and run it HARD, in a pinch I have run cheap offbrand and ran it HARD, no issues. And mine is a rarely serviced 450hr engine
here is a good read on 2-stroke oil, its an older aticle, but im sure the tech hasn't changed since the whole world is switching to 4-strokes
