Engine wise , oil change including filter is 6.7 litres
Gearbox is until it runs out of the filler hole! as is transfer box. (Gearbox is ATF and transfer is EP90)
Both are less that 4 litres, but can't remember exact figure. I can get it for you from the Haynes book if you need it.
Axles are about 2.7 litres of EP90
