I'll be changing my fluids this weekend, to include front/rear/TC/tranny. When changing the rear diff, the manual instructs to use Mercon SP which I purchased (Amsoil brand). The question is, do I need to add any type of rear diff additive? I read somewhere and watched some DIY videos that also included additives for the limited slip, etc. The manual doesn't say to add anything so I am assume, use ONLY Mercon SP?
BTW, I own a Gen2 4.6L 4x4. Thanks in advance!
