Need friction modifier with this gear oil?
Hey guys,
I got some "Masterpro synthetic gear lube 75w90" for first servicing of my front and rear diffs.
I have the LSD Dana 35 in the rear and Oreilly told me this synthetic did not require a friction modifier but I do not believe them yet.
Here is a picture of the back of the bottle where is says " Can be used to make-up or refill of Limited slip/positive traction rear axles".
Should I just run the synthetic with no modifier and see how it goes and then add some modifier as necessary or just go grab some and put 3.5oz in?
I am uncertain about the condition of the clutches back there (first time opening her up).

I had the synthetic because I was going to use it in my AX-15 until I learned about GL-5's sulfur content and brass synchros.
