It was a few years ago, but I've changed both differentials oil. I believe I remember that I do not have a limited slip differential in the back (can someone remind me how to make sure of that) is it on the tag bolted to the cover ? Or somehow coded in the VIN ?
Anyway, I bought new Mobil 1 75W-140 for the rear as I plan to change the rear bearings and seals. I noticed when the new oil came in the mail that the label said, "limited slip friction modifier included".
I realize that you need to add this modifier if you have a LS diff. But what if the case is that I do NOT have LS differential...is it safe to use gear oil that has a friction modifier included in a non LS differential ?
