UGGGGGGG! The very first thing that book wants is for you to become an affiliate, I gave it three pages of my attention and all three were selling memberships.

The book has motives other than educating the public on motor oil, its a marketing scheme and might be why Amsoil comes out looking so well in it.
I did not pay too much attention to that, if for no other reason it made little sense.
I did go to the bottom where the results were, and when needed, looked up a bit in the document for what the implications of each rating was.. regardless, these types of things needed to be taken with a 'huge grain of salt'.
It did occur to me there may have been an affiliation with "TheOilSite dot com" and Amsoil, and I did look up who the owner of that site is, and he is not listed as an Amsoil dealer.
As far as their business model goes, I've nothing per se against a multi-level marketing system...
HOWEVER - after experimenting for quite some time on multiple computers....
Here is what I see when first going to "Amsoil dot com", see the "Find Amsoil Near You" in yellow?
After clicking on that, then typing in a zip code, I select one of the dealers websites, here is one of them:
THEN, after I click "Shop Online", I am re-directed to the Amsoil shopping site - so apparently it is a drop ship system where referral $ is involved - which I *suppose* is ok...
BUT - when I go back to the original "Amsoil dot com" site, notice how the yellow "Find Amsoil Near You" button is gone?
Obviously a cookie was set in my computer... but that turned out to be a *particularly* tenacious cookie, which I REALLY did not appreciate.
I'm fairly sure that I can say with confidence, that I will never ever be buying any Amsoil products... that type of business is not my style.
I am more of a 'keep things honest, straight forward, and simple' person.
