just wonderin what kinda oil to run in the transfer case...

 

AMSIOL 75w-90. We use this in ALL our Evos that come into our shop. We run this weight oil in all three items...Trans, transfer case, and rear diff. We also put AMSOIL 10w-40 in the motor and many have noticed the difference in performance as well as noticing a smoother running motor.

The ONLY other gear oil I'd suggest would be Motul.

 

TRE, Buschur, and Shepard only recommend the OEM factory fluid for the T-case. You can get it at the dealership for like 40 bux.

 

I just changed the original TC and Diff oils(12,000 miles) and am trying Motul FF Gear Competition 75w-140 oil, and all whirring noises from TC and Diff decreased dramatically. The stuff is expensive though.

 

Mitsubishi Diaqueen LSD oil!
