Hello,

Can somebody please check if I used the correct oil in my diff?
The system at a autoparts warehouse said: 80W90R so that is what I used. (Valvoline 80W90R)
Now I checked in RAVE and it says: 75W90R

Please tell me it is correct and I don't need to drain the diffs and replace with 75W90R

Thank,
Alex

It's been a few years since I did mine last, but IIRC it was 80/90 synthetic.


Edit: I just went out to the garage and saw I have some 80/90 non-synthetic. :think: I could have sworn it was supposed to use synthetic...Oh...I used that in my old Jeep.

Summary: I have no idea.

You are fine. There would be no issue with even mixing 75/90 and 80/90 as long as you aren't mixing dino and syn.
