I added .5 qt x 2 and i'll be at 10k this week. 1 bottle in 10k miles. Seems reasonable.
Half a bottle put me from min to nearly max the first top off. Never dump the whole bottle guys! I carry a couple of bottles in those nifty bmw oil pouches.
Tech, of course your car burns oil, its overloaded with all those sweet mods! Jk!
