Or maybe they just don't want to subject their claims

Uh huh.  Well, they certainly wouldn't have approved
of Amsoil at that time, either, because Amsoil 
basically said that their oil was *too_good to bother
with API certification.*
I don't know the current quality of their product,
but I just looked at their web site, and was amazed
to see that most of the unsubstantiated, pie-in-the-sky
claims of the quality of their oil, and anecdotal 
endorsements - which were there several months ago -  
were removed - (before, it would basically do everything 
good you could imagine, except maybe wash & wax your 
car for you) and that they now list their motor oil
as API certified.
Maybe if they establish themselves as a reputable
company with a reputable product someday, I'll consider
using it, but until then, I won't accept their claims 
of superiority on blind faith, thank you very much.

No argument here.
