Just wondering, since the D15B LSD is a viscous unit, anyone out there know if you have to use a special oil with this, or if the diff is sealed from the box oil and MTF is fine?
Found myself a box and its going in after christmas, but want to stock up on the swap bits, and get the feeling if it is a special oil, its not going to be easy to get hold of.

Tried the dealer option and got no joy, so if anyone can confirm if MTF is fine i would be well happy
