If it is not leaking out there is only one other place it can go and that is out of the exhaust pipe. Sometimes an engine can use lots of oil and not make any blue smoke out of the exhaust. Oil will not just mysteriously vanish. How many miles on the BMW?


Maybe it's evaporating?

Marvel Vanishing Oil?? LOL

Did you change the Crankcase Vent Valve and associated hoses? When the valve fails, or the hoses develop a leak, you will use oil excessively. I would start there if it's original to the car. You probably have over 100K miles by now.
