In the same note, so long as the fluid meets and is certified for the specification, it should be fine. Otherwise, I would imagine you would ONLY use genuine BMW fluids--genuine BMW engine oil, genuine BMW DOT4 brake fluid, genuine BMW rear differential fluid, genuine BMW BlueDef (if you have a diesel), and dare I say genuine BMW washer fluid? A bit overkill. If the fluid didn't meet specification, that's a different story. Of note, I stuck with genuine BMW transfer case fluid as there's no substitute, given there is no listed/known specification for it. Of course, everyone is welcome to use what they are comfortable with paying.
