I don't think the Euro formula of PP 5w40 is mostly group IV. I think they said it was group III+ in their question/answer session with bitog. Though they were talking about Ultra Euro 5w40 but I don't think the platinum would have it if the ultra doesn't. That's not saying anything bad at all about it, I have some myself, as per your point a lot more goes into making a quality oil product that just the basestock being group IV or V.
