So I was planning on replacing my differential oils and transfer case fluid. I've thoroughly researched which oils I should use but I just wanted some clarification. I have a 2012 g37x, could I use this for both of my diffs? https://shop.advanceautoparts.com/p/...w573/7070039-P
I know the manual says 80w90, will this mobil 1 75w90 work? I plan on getting 3 quarts for front/back.

As for the transfer case, I found this (which is a good replacement for nissan matic J):
Will these oils do? Wanted to hear opinions etc. Cheers!

 

I used full synthetic mobile1 75w90. Ran that for 20k miles and when I drained it, it was extremely clean; so I'd say it's doing its job. For the transfer case, I want to say I used Redline for the transfer case. Just make sure it's Matic S compatible and full synthetic.

 

Transfer case: Redline D4
Diffs: LE-1605 I also use this in my S2000. (https://products.lelubricants.com/it...304/1605-quart)

 

Thanks for the advice gents!
