From Metroplex; I questioned him about why Amsoil claimed their 5W-40 met a non-existing Mercedes spec and removed the claim when I presented them with the info that it didn't exist. I also asked him how Amsoil ATF manages to meet Mercon, Mercon-V, ATF+3, and ATF+4 when ATF+4 is a HIGHLY friction modified ATF whereas ATF+3, Mercon-V, and Mercon are less friction modified.
