I had 15w-50 in my engine for a few months last summer to cut down on lifter-tick when it got very hot out. Again, no problems.
I agree that you can run whatever you want in there, it's not like the engine will blow up if you don't use the magic BMW oil or anything. Just stating what was the "approved" oil for this car. I've always run 0w40 in my cars all the way back to the veedub days, nothing but good things to say about it. Next time I will try castrol 0w30 though, I hear even better things about that oil...
