are you sure? I've always read.

It's much simpler for your differential. ALL BMW differentials use Redline 75W-90 Gearoil. This is ideal for open or factory limited-slip units, as well as the torque-sensing type if you are lucky enough to have one of those.

Nex to maX, but I've been getting stuff from this shop for a while. He sells all the good lubricants.

how often does the diff. fluid need to be filled?? what are the symptoms of fluid needing to be replaced.

[Mystikal]

Every year is good measure. There shouldn't be any symptoms of it needing to be replaced, it's a maintenance item; if you get any bad feedback it's already too late (like motor oil, or any other fluid).
