By said logic, no one should be using amsoil as no car manufacturer recommends it.
I suspect that it amsoil had a TC-W3 rated oil, Tim would be telling us to use it. He'd have some amsoilcentric tests too.
No, the auto manufacturers recommend the API classification and SAE viscosity. Which AMSOIL and many other oils meet.
The auto manufacturers do not recommend 2 cycle oil.
AMSOIL does have a TC-W3 rated oil. http://www.amsoil.com/storefront/hpi.aspx?zo=1181889 . They and I do not recommend it for use in 4 cycle engines. Just like all the other 2 cycle oil companies and auto manufacturers.
