I called Mistubishi in SLC today cause im going to do my transmission service and Transfer case service. The techs there dont seem to be much help and they say the front is GL-4 Gear oil either 75-80 or 75-85. I asked if i use mobil one and he said it would be just as good and i asked about the transfer case and he said Mitsubishi LSD Gear Oil or equivelant and i have no idea what the difference is.

Is there any suggestions or should i just stay with GL-4 up front and buy a quart from mitsubishi for the transfer case?

I have the 5spd btw

 

I use diaqueen Gear oil for Rear diff and tc, and redline mt 90 for the transmission
