Synth Diff Fluid, which one?

["Alexander van Gerbig" <Audi_80@email.msn.com>]

    Local shop uses Pennzoil exclusively and says Pennzoil Synth Diff fluid
is good stuff.  Although he told me to find out what the best is for Audis.
What is the best synth diff lube for the 3 speed autobox out there?
Redline, Mobil 1, Pennzoil...?   I am going to use Castrol Synth ATF with
3oz of Militec.  The diff will also get some Militec as well as the oil at
the next oil change.  It looks like that stuff really works at cutting
friction superbly.

Thanks!
