Im going to run a UOA of 0w-40 in a few weeks thats in my 4.0 right now. Im excited to see the results, i haven't found any UOAs of ow-40 in jeep 4.0s yet.
That would be interesting, other UOA's of Mobil in Jeep 4.0's haven't been very good but the 0w40 is supposed to be a different breed of cat. I'll be looking forward to that one.
x2. I also find it interesting that Mobil 1 leads to higher amounts of iron in UOAs than other oils, especially since Mobil 1 high mileage has more ZDDP than other oils.
