Differentials - Red Line 75W90, the 75W140 is not for LSD so don't get confused. You'll need 1.06 for each diff so get 3.[/QUOTE]
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?
