Just changed the oil in the differential and 6-MT transmission in my 128i. I used Red Line MTL in the transmission and Red Line 75W-90 in the differential, per Mike Miller's recommendation. The diff oil was still clear-yellow. The transmission oil was dark and really stinky. I didn't notice any difference in shifting after the oil change.
