2017 BMW X3 XDrive28i (F25) M Sport
At 84,000 miles, the gear oil looks really **bad**! This should have been changed every 50,000 miles, if not every 30,000 miles, just like on my Lexus All-Wheel-Drive!
Again, replace your gear oil in your differentials and transfer case every 50,000 miles, or even better, every 30,000 miles. Your BMW xDrive will run smoothly for a long long time!
