I wanted some opinions about factory fills. Do you think they still or ever put in special additives? I am not talking about flat tappet or custom built engine. I am talking about your average vehicle rolling off the assembly line. It is my opinion that the factory fill on my Jeep is Pennzoil yellow bottle. I am not saying that is a bad thing. I have always heard that the factory fill has "special additives for proper break in." I just don't think that is the case, at least not anymore.
Opinions? Facts?
