Full to empty on the dip stick is about 1ltr.
I use 10w40 Semi Synth from Smith and Allen. You'll need about 6 litres to fill her up. Buy it in bulk to make the saving!
Diffs are 75W 90R gear oil. About 2 litres at each end. Again I use Smith and Allen.
Autobox and Transfer box are ATF Dextron III. The autobox needs 11 litres! Although when you change the fluid, you don't get it all out, so in practice you'll need a good bit less. 2.5 for the transfer box. Again, Smith and Allen is your friend here....
