Sounds good to me. How many miles on the truck? Might be worth running a short interval first, as it cleans up all the gunk, and gradually begin increasing OCIs.

It is a quality oil and I wouldn't be concerned about using it, I have seen a lot of good results with it.

Why are you interested in switching?
Because only a donkey would use conventional oil.

Fuel economy probably won't increase. The 0W-40 is a pretty thick oil. If it were me, I'd do the 0W-30 AFE instead.

With high quality Group II base oils being used in conventional oils these days, if you are going to do 6k miles oil changes or less, then there will really be no advantage in using synthetic over conventional.

Unless your engine is burning oil or leaking oil, most often a good synt is always better than dino. The M1 0-40 will be a good choice.
