Well, I happen to really like the VW brand synthetic
but since it is almost $22 a quart most folks don't use
it!  I have had good reports from most of the major
brands such as Redline MTL and Amsoil.  I'm sure that
other people have had good success with other brands.
What is important is that the oil is a GL4 rated gear
oil.  Other ratings such as GL5 and 6 can contain some
sulphur compounds which have been noted by VW to
attack the type of brass that is used in the syncro rings.
To counteract this all of the syncro rings in the later 091
gearboxes are now fully moly-coated and VW switched
to their 'flavor' of synthetic GL4.
