I realize there are going to be some opinionated responses. I'm just having trouble actually picking a brand. Manual calls for Mopar 80w90 I think for diff oil on the Dana 35&Dana 30. Not sure about the trans oil (5spd manual)
I'm running 0w-30 mobile 1 synthetic high mileage in the 4.0. I think it's had conventional oil since before I owned it, I flushed the oil system with 5quarts before filling it (happened on accident).
Do y'all have any complaints with diff oil you've used in the past, or recommendations on what you feel is the best for your tj.
