diff oil question

Hi everyone,
Recently i have put 2007 sti transmission, axles, shaft and differential
to my MY03 wrx. They work pretty well and i'm delighted with it
What i want to ask is: i have put mobilube 75w-90 to transmission, there is no problem
with it but the confusing part is the diff oil. After lots of search i filled it with
mobilube LS 85w-90(fully synthetic lsd oil) What i learned is 2007+ sti diffs are
torsen, nor clutch type so they don't need the subaru lsd oil but just some synthetic
oil compatible with LSD. What do you scooby experts think? Is it ok?
Also i have another rather unimportant question As i don't have the DCCD is the
default mode of my diff is fully locked? So am i driving it locked all times?
Sorry for the writing so long but i'll be very greatfull if i can get an excact answer
to these, Thanks a lot

Re: diff oil question

I thought the dccd was centre diff control, nothing to do with adjusting the slip of the rear diff.

Re: diff oil question

This is what I use in my rear diff and what was recommended to me by the Opie Oils guys.

Motul 90 PA Lubricant limited slip differential (LSD) Extreme pressure

Mine is a 99 STi RA thought so not sure if it is necessarily the best oil for your rear diff. Why not add a post the thread below asking what they think of your choice?
