I see. The non-slip gear oil is for open transaxles because it does not have the friction modifiers that a LSD requires. It describes the properties of the fluid, not the use of the fluid.
I have seen recommendations for the 75W90 NS in the LSD and the MT90 in the non-LSD. I thought that was backwards.
The BMW people seem to use Royal Purple instead of Redline. Something to do with API certification. I had Redline in my 944 and thought it was great.
