thanks for this.

sorry im a little confused - which one are you saying you used the 75w90 or the 75w140?

I was told MY06 X3`s are not LSD - so which one have you gone with?

Ive just foundout i can sourc Redline 75W90 GL-5 Gear Oil or Redline 75W-90 NS GL-5+&6 Gear
which one is correct?

thanks[/QUOTE]

None of the X3s have a limited slip differential. Either weight is ok to use. Most use 75w 90 with good results. I used redline 75w 90 when I changed mine.
75w 140 is more for racing applications or if you beat the snot out of your x3.
