This what I used .sd4 2011 . Transfer box miller's ee 75w 90 .rear diff Castrol epx 80w90 . automatic fluid Carlube ATF LV .engine oil Granville 5w30 c1 .all good

Thanks Sunny and Jimbowats

Going back to the transfer box fluid, the BOT118/95 is fully synthetic whereas the universal fluid I found is only semi synthetic.

Castrol do another gear oil called SYNTRAX 75W/90 GL 5 long life, fully synthetic and I’m sure will be ok for the transfer box.
If anyone else has used this I’d welcome any feedback.

Fully synthetic

Haynes manual recomends Bot 118
which is a 75 90 gear oil

although I had one recomendation that it was an automatic transimission fluid

so a bit confused
