Edit: Doesn't have to be Red Line, I suppose. I've seen BMW's own recommended too.

So I do not have an LSD on my car, so I can use whichever 75W-90 or 75-90NS there is? Also heard it has to be GL-5 if I'm not wrong? Also do you know how much of the oil do i need? Some people also seem to recommend 75w140.
Same issue I am having with the gearbox oil, seems like I need to go for 75w-90, but they still have different specifications, like MTF-LT-2, MTF-LT-4 and so on.
Sorry for all these newbie questions, just freshly getting into maintaining my cars and want to make sure I know what to look for.
