No worries. Car may come with the separator but oil is still everywhere. BMW knows how to make a vehicle, no question about it. Problem is, not everything they do is 100% efficient. You can check the amount of oil yourself. Take off your charge pipes and watch the oil drain out. Our test car had less than 5k miles and oil literally dripped out of the charge pipes. For efficiency of a turbo motor, the an oil catch can will provide longevity to the car. You don't have to take my word for it. I advise everybody to check themselves. Better to know 100% than to assume BMW made the perfect setup.
