Yes, I sell AMSOIL, and yes, the Website is one of my sales tools. I only post the test because Fast Fours and Rotaries is generally considered to be a quality publication (by me and others). The tests were not done by the AMSOIL company, nor were they paid for by the AMSOIL company. The infomation given is probably a little vague because of the nature of the publication. If you wanted more specifics, I'm sure you could contact Fast Fours and Rotaries direct. Again, my apologies if I did not make it clear that the url submitted was an article on my AMSOIL website.
