Anyone use 75w-140 in their WK2 SRTs? I'm about to change my diff fluids and was contemplating switching from 75w-90 to 75w-140 but wanted to see if anyone had an opinion to share regarding that. I very rarely ever tow anything and I never have more than 2 other people in my jeep with me. But I do like to get on her quite a bit.
Was thinking of Amsoil Severe Gear 75w-140 or Royal Purple 75w-140....thoughts? And do I need the Mopar additive for the rear diff with either of those? Or do they have it in it?
