    Should just be normal gear oil as I believe its a viscous center diff.

      i think it should be a gear oil made for lsd use

        Use a synthetic gearlube. I use 50-50 mix redline mtl and heavy shockproof, and have used royal purple without any complaints.
        '90 AWD Protege, full GTR drivetrain swap, ~320 whp daily driver, RIP, and
        '90 AWD Protege, yet another GTR swap, Open class rallycar with a Toyota GT4 gearbox swap, thus crossing the line between hobby and mental illness. And a Brabus E55 K8, removing all doubt.

          Have you tried straight light shockproof?

            Not yet, I have a quart o' that stuff in the gearbox of the streetcar now, and from the weight of it, I wouldn't hesitate to run that in the centerdiff.

              Viscous limited slips are almost always sealed units, they have a special high-friction silicone oil that is non-lubricitive internally, so a normal gear oil matched to the differential design would be best. Some of the high-additive oils might be a bit much, you want something that can move a lot of heat around as viscous units operate on heating their internal oil and therefore the case and gears have a lot of thermal stress

                You must be talking about the transfer carrier which has his separate fill and drain plug on the transmission near the drive shaft flange, there is no lsd in this part of the transmission. You can use any good synthetic gear lube in the 80w90 range.

                The center diff is a sealed unit in the other part of the transmission casing. For the transmission you should use a thin oil like redline mtl if you are in a cold climate you can use ATF oil. It really make a big difference in shifting.

                  Since I last posted in this thread, I've done some more gearlube research. I agree fully that the centerdiff should have synth. 80w90, or heavier. As for using lightweight no shear strength gl4 ATF in the gearbox, well, I think that specification is a (small) part of why these trannies blow up. Go here for the full story,
