Mmmm I could actually be incorrect regarding 0w30 oil. I just know a lot of manufacturers started going to it to increase gas mileage. I thought to fight against consumption they also did things like go to thinner rings for less friction, etc. I read something about a lot of newer engines having problems with consumption due to the ultra thing oils.
The first digit is the relative viscosity of the oil on startup, the second when it is hot. I'd just go with a BMW stamped oil under warranty and change it at regular intervals.
Edit: Perhaps I was thinking about subarus with the ultra thin 0w20 oil, disregard my previous posts.
