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
