Wow- I was just coming in to research this very question. I've got a 2012 650, and though I've only got 5,700 miles on since April, I've now had to put 2 quarts of oil in.
I know turbos cook oil, but do they drink it that fast? Definitely a question for the service guys when they fix my seat.
After a quick search of the internets, seems it's not at all uncommon, at least for the V8s. 1 quart every 3300 miles seems to be about average. Bet no one factors that into the total cost of ownership!
