As well, it seems like every time Amsoil publishes a test for anything, it goes Amsoil, a gap to Mobil 1, and then all other comers a similar distance to that between Amsoil and Mobil 1 behind Mobil 1. I am not saying there is manipulation, but I am saying it always seems to appear that "if not for Amsoil, Mobil 1 would be the best" in those tests.
I am sure that ExxonMobil doesn't want to step on the toes of a big customer, and that Amsoil is somewhat dependent on that XOM business relationship. There are only so many suppliers of PAO out there, and ExxonMobil happens to be the biggest. Amsoil dealers (I am not saying Pablo and Gary and Don, but there are a lot of them out there who are not that reputable) seem to talk a lot of trash about Mobil 1, but Amsoil itself takes the high road.
I am sure that Amsoil is comfortable with the situation, as is Mobil. Amsoil makes good products, as does Mobil, and really as far as major brand oils are there even really bad ones out there?
MGregoir, I am not oil analysis nor know anything about oil at all, just regular consumer tried to find what best oil out there, but it seems like Amsoil is good according the people this site. I have found a guy that knew a lot about this Aimsoil from other Nissan site his user name il_signor. Why don't search for this guys and read what he wrote about M1, Aimsoil, PP, and Castro 0W30 from Germany. I hope I get his right.
