Question about Quaife Differential, What type of fluid would you use?

[Jackson Zimmermann <JZIMMERM@exch.co.albemarle.va.us>]

Following that long set of questions and answers regarding handling and
suspension mods, I have decided to change my driving style to the point
and shoot style versus the traditional apply power 1/2 way through the
turn that works so well with my other car.  So I'm getting ready to
install my Quaife and have a quick question to those of you out there
with Quaifes.  What type of fluid would you use?  I'm planning to use
Mobil 1 90wt synthetic gear oil and wanted to see what everyone else
uses...  TIA
