I think ya'll are wrong with this idea that thicker oil is better. Vast majority of engine wear normally happens immediately after a cold start. Thick oil makes this worse. Synthetic oil has far better flow characteristics (see Curt's test of M1 vs. Dino in his freezer from years ago) and helps in this case.
Oil is not only a lubricant but also plays a very important roll in cooling the engine internals, and for cooling you want a high flow rate. Thinner oil will flow faster, provide better cooling. 0W-40 is the best of both worlds, for diesel. I use 0W-30 in SWMBO's Infiniti gasser motor. That is at over 250k miles and doesn't burn a drop.
