I have trusted Amsoil, just as I have trusted Mobil 1 (M1 HM in a girlfriend’s sludge-free 5sfe), Pennzoil (PP previously used in my car (1zzfe) and T6 in my father’s truck (22R) with 348,000 miles), and Castrol (used previously in my car and a friend’s car (3mzfe)), for a while now. I have verified them by using them with no discernible harm to the vehicles, all of which have over 100,000 miles so they are just getting broken in as far as I am concerned.
Just because a company chooses not to pay licensing fees does not mean they are hiding anything. I cannot believe that this website has devolved into discussing conspiracy theories against Amsoil. What I am reading here is that licensing is such a monumental concern that Amsoil not licensing the SS line of oils means they are hiding something. Are you kidding me? Besides, once a product is licensed, is it VERIFIED that each bottle coming off of the production line meets the specifications of the oil originally tested? Of course it doesn’t, and it would be unreasonable to expect such a thing; so now you still have to trust the company producing the oil to always meet the specifications verified by the “third party” company during testing. Why not just use the common sense the good Lord gave us and look at the history of good results produced by a company’s products?
In the end, you have to trust someone, so if licensure is a make or break detail for you, I have a case of Belco motor oil and some OCODs you may be interested in purchasing.
By the way, it is "Trust, BUT verify." Also, that phrase is actually a proverb from another country taught to Ronald Reagan by Suzanne Massie.
