BMW's actual specificaation for normal oil consumption is 1 quart every 1500 miles !!!! yes.. most cars never see that, but it is very common to have to top off inbetween oil services..
Your car should have an elastic band on the inner trunk panel on the left side( drivers side ) Guess what quart sized object fits in the strap
Keep driving... enjoy, life is good !!
