But interestingly, I've now gone a couple thousands miles since that dealer service, and I haven't had to add any oil to my 650i! Somehow the first service "fixed" the issue in my case.
I'm adding this tidbit just to confuse the situation even more. Somehow my car's oil consumption issue changed after the initial service. Maybe the tech fixed something and didn't note it in the service notes.

This was my experience as well.
