When choosing a oil I would choose one that has met the OEM, MIL, ASME specs for the 3rd Gen Dodge Ram with AAM Axles. I would also choose one that I could find at local distributor. That way if I was in a pinch, at home or on the road, I will be able to find more if needed.

Regarding 75W-90 vs 75W-140... any input about fuel economy with the thicker stuff? Seems like the added drag would cost 1-2 mpg.

red line shock proof 85-250 actualy has les drag than most thinner oils... probably not enough of a diferance to be mesurable in out trucks but it cant hurt.
