Manual transmission --- 80w-90 for the gearbox and transfer case diff is 80-90 oep if a straight diff and different if a limited slip diff gear box is around the 2.5 ltrs as is the diff each LiSiD oil can be used in LiSiD diffs and straight diffs but straight oil cannot be used in lisid diffs the transfer case uses the same as the box but the quantity you will have to check in the lubrication section of the user manual many user manuals recommend a lighter straight oil for transfer cases and boxes ( 30 straight oil) but I find that the light oil promotes bearing wear and gear problems as the oil squeezes out under load

diff is 80-90 oep if a straight diff and different if a limited slip diff gear box is around the 2.5 ltrs as is the diff each
LiSiD oil can be used in LiSiD diffs and straight diffs but straight oil cannot be used in lisid diffs
the transfer case uses the same as the box but the quantity you will have to check in the lubrication section of the user manual
many user manuals recommend a lighter straight oil for transfer cases and boxes ( 30 straight oil) but I find that the light oil promotes bearing wear and gear problems as the oil squeezes out under load
