There are oils made specifically for DFI engines one by Driven, DI40, is well spoken of on facebook 911 groups - in many cases by people who have had their used oil analysed. I'm going to try it next time, and I will have an analysis done on my current oil (Mobil 1 5w40) so that I will have something to compare with next time.
