True, but that has been the case for many years. Although diesel pick up owners tend to hold on to their trucks longer than the average vehicle. But speaking from the manufacturers side I would hope they wouldn't make their service recommendations based on the average length of ownership. That would be unfortunate.

The only way high end oils make sense to me is for running extended drain intervals, but you must follow the EVIC for warranty reasons. Any 10w30 that meets the CJ4 requirement will work just fine. On a side note, a friend of mine owns a 2nd generation 6.7. He was just telling me the service intervals for the transmission are 150k miles. To me, that's just crazy. Ive been around automatic transmissions that tow and by 50-60k miles there is a good bit of clutch material in the pan and the magnet and the fluid has turned color. 150k miles in a truck with 800 lb ft of torque that is designed to tow is torture on any fluid. Ford must really have a lot of confidence in their transmissions.
