I just noticed in the items for sale forum that someone is selling Amsoil ATF+4, and that the bottles actually have "ATF+4" on them. I was aware that Amsoil claimed that its universal ATF met ATF+4 specs, but for them to actually bottle a fluid and call it ATF+4 is not kosher, IMO. ATF+4 is a registered trademark (as is ATF+3), and DC has not licensed it to anyone for use on any aftermarket service fill fluids. In addition, the exact formulation of Type 9602 fluid is tied to the ATF+4 trademark, which is one of the reasons that no company has produced an aftermarket service fill ATF+4. Chrysler has not released the formulation for use by anyone other than Equilon and PetroCanada, which are the two companies that make Mopar ATF+4 for DC.
Amsoil may make great products, but this is just another example, IMO, of their questionable business and marketing practices. What is in these bottles is NOT ATF+4, and to say it is borders on fraud.
