Over 170k miles, still OE guides. BMW did all service up to 100k, after that all oil changes have been done when the 3rd green light goes out, M[1] 0-40 LL spec.

EPDARKS, you might want to instruct posters to include climate where their X is used. I would think extreme thermal cycling (sub zero to operating temp) shortens the life of ALL hard plastc parts.

Hot climate, FL and TX X for over 10 yrs.
