I have a KAAZ and use a combination of cheap GL-5 non-synthetic (Castrol Hypoid C 80w90) with ford friction modifier. KAAZ specifies to use NON-Synthetic oil because of additional slipping of the clutches, so I guess each manufacturer has their own theories.
Like mentioned above, its a used diff, so dont worry about break in. Just be sure to change the oil every 2-3 events or with every engine oil change when steet driving. If your concered about doing maintanece, you should look into getting new clutch plates.

Although it does appear that I am wrong about the Nismo unit requiring a non synthetic oil (learn something new every day). In fact based on some quick research it seems that Nismo actually recommends a LOW FRICTION 75w140 synthetic oil to be ran in their diff. Here are some links related to your question.
Nismo 2way diff oil? Which oil type to use? Synthetic????
nismo 2 way lsd, what oil? - Hardtuned.net
I also found this on the Nismo jp website
NISMO | Notes on installing NISMO LSD
That link contains a bunch of info on your diff including what weight oil to use as well as a link to the rebuild kit if you wanted to completely rebuild the diff while its apart. Based on the information I found on the Nismo site I would say that Redline 80w140 should be fine to run in your particular diff.
That's probably way more information then you wanted but I'm board and this helped me procrastinate on finishing my term paper lol. |
Thanks guys!
Thats the exact answer I looking for complete with the link to Nissan!
I'll try to remember to take some pictures and maybe to a little DIY when I take it apart.
I'm going to try to see what type of condition the inside are because going over this diff it looks new, just dirty.
We'll see after the inspection.
So bottom line from all this info:
Nismo: Synthetic Ok!
KAAZ, Cusco, Tomei : Synthectic Not Ok... HAHA!
Hope this info helps someone...
