I haven't seen enough engines run on silver bottle Husky oil to say for sure, but it has seemed ok when I have ran it.I'm not a fan of Husky oil. None of their offerings are true synthetics. I've notices over time that the saws that I see running it are dirtier than others as well.
Writing off a oil because it's not a "true synthetic" isnt very sharp. There are full synthetics that suck azz, just as there are blends and mineral oils that suck azz.
