I can only assume the incorrect amount of oil was put in (unlikely since I measure out 8.8qts when I change the oil)... Or the dipstick is reading correctly.
Either way you should plan to change the oil around every 7500 miles, not the crazy 15k miles interval suggested by BMW. Within the 7500 miles you should only need to add 1-1.5qts. YMMV of course.
