15K change intervals....
i haven't had any problems with my bmws, but i'm glad i won't have any of them long term...especially having two twin turbo cars.
i'm not changing the oil--it's on bmw's dime. some other schmo will cross that bridge.
my 525xi didn't use any oil. when i traded it, it had 11K on it, and it's original oil.
but then again, i couldn't really tell--only what the computer tells me.
