There are numerous threads on the n20 noise in various BMW forums. Oil type is seldom the fix. It's just the nature of this DI engine and it is not a nice noise either.
This. My wife's old 328 was the same way. I got so so used to that distinctive sound from hearing her's that I could tell from the sound when walking through a parking lot if a 328 was coming up from behind me.
