What kind of sound? exhaust note, ticking, rattling?

You said "BMW"-- not a specific model or platform-- for comparison, I have to look at the tach of my E38 sometimes if I'm distracted after starting-- and when navigating parking lots, walking pedestrians never hear me patiently waiting for them to move out of the center of the lane.
Based on my experience, and those of reliable others: Don't put anything in your crankcase other than spec oil, and lubri moly products. [that suggestion is NOT an invitation to open a discussion of what snake oil is best / why, or why I think this or that. Just my 0.02, that's all]
