Hi all, my R60 JCW ALL4 is sitting at 117,000 miles, and I don't see the manual mentioned anywhere if the differential and transfer case fluid change is needed. Does anyone know if this is necessary? If yes, is Differential Fluid - 75W90 SAF-XO GL-5 Gear Oil (part number 07512293972) the right one to use? How many quarts will I need?

Thanks in advance!

 

I used Ravenol in my F60 when I swapped out all the driveline fluids. Here is their oil finder:

The transfer case should take about a liter, the differential should be about a half liter. I can’t remember if the R60 hang-on clutch has a separate fill.

Transfer box and differential should be changed every 50k miles.
