The funny thing is that my humble 10W40 passes all these tests and consequently the stringent ACEA A3-02...

I think this is accuarte but if not someone jump in. PAH is a group of compounds that can/do cause cancer. Old style GP1 oils, Napthenics of low severity refining and some diesel type fuels. It maybe shown due to the type of oils used as a "diluent" in some of the supplied additives. Think stands for "Poly Aromatic Hydrocarbon" of which there is none in a PAO or a GPII/GPIII oil. bruce

HOB in this context refers to "Highly Over-Based." These calcium components are detergents and rust inhibitors. The first component in the list is simply an amide borate ester. The last item is an anti-oxidant.
