If you want that sort of thing, you should get Pennzoil Platinum 5W-30 european blend. Bob the oil guy uses it.

The thing that bothers me about Castrol Edge is I have read multiple reviews saying it is a dirty oil. There is also a video on youtube comparing it to BMW Oil and the BMW oil seems cleaner. This a concern in an engine known to burn oil. You want an oil which produces little ash.
I think that YouTube video test actually shows the bmw oil to be sludgy and the castrol holding up better?!?
