I've talked to the techs at Amsoil and they have said that Dominator is an older formula that is designed 2 make engines live through a race or race weekend and then torn down at whatever interval is determined. Not sure how this relates to saws at all except lots of people I know are very happy with it in saws as far as I can see. When I asked him questions between Interceptor and Dominator for my KTM woods bike he asked me how often I tear down the engine to inspect. I said uh ....never lol and don't want to unless I have to. Obviously, this is for larger dirtbike engines and sleds. I run saber just because I have had really good luck with it and like what I see when I peek in the exhaust port and plug hole. The saws I have been in to look well oiled down below.
