Has anyone changed their Gearbox or Diff oil?

Did you notice any difference and what did you use?

Will order some fill & drain plugs, any other tips.

I'm thinking of changing mine and have found the following oils to choose from:

Gearbox GL4 type - requires 2.7L
Millers CRX 75W90
Mobil VS200
Castrol THF-X

Diff GL5 type - requires 1.5L
Millers CRX 75W90
Mobil SHC 75W90
Castrol SAF-XJ

Also with my new Big Reds and new rear calipers waiting to be delivered along with Goodrich RS2 braided brake hoses (new from vagparts), new hard lines, DS2500 pads and a new bomb I am looking at trying ATE Super Blue brake fluid; any experiences of this or any other suggestions?

Yes but specialist did it. Could check if oil type on invoice ?

ATE Super Blue brake fluid no problems, I used the car on track with no fade, this stuf is so good it warped my front discs

Go for the castrol oil on gear and diff.I just changed on mine and made my gearbox feel like "new" Especially when its cold like here in Norway. Thumbs up:) I also bought the same brake fluid as mentioned above and its great combinded with my new brakes:)
