A little oil usage is not a problem. I had 0 oil usage with a '99 540i, significant usage in an '02 M5, light usage in an '08 550i, and now have added 2 quarts in 15,000 miles with the X5 50i. I believe it is a blow by with the piston rings, especially when the motor is cold. With the M5, I could see a little smoke from the exhaust when cold. It used a quart every 1500 miles when new, and 3000 miles once some age. I believe the purposely loose tolerances is why M motors now use a much heavier oil than 5w30.
