Hi, can anyone recommend what transfer box oil I would need for front and rear box's. It's a 2007 3.0si X3, thanks.

Front and rear diffs are 75w90 or 75w140 synthetic gear oil, transfer case is special TF-0870. From BMW about $70-80. I use Mobil1 75w140 full Synthetic gear oil, and the BMW transfer case fluid. Depending on production date the rear diff might not have a drain plug, you will have to suck it out if that's the case.
