Looks like mine doesn't need any oil either. No noticeable use after 4000mls
Looks like at least Stealth and I who did drive a lot of mountain passes during breakin have something in common
Certainly driving mountain passes (up/down) is great exercise during breakdown (varying revs, oil being sucked and pumped through the engine/cylinder during acceleration/breaking etc) .
I wonder if there's a relation to how people have broken in their cars and the oil consumption , but in the end it might just be a small percentage and still within the BMW advised range.
