I read the same thing in the manual to use motorcraft cetane booster and the use of motorcraft antigel additive in the winter months.
From what I've read in other threads, the additive and cetane booster like motorcraft, diesel kleen (power service), etc, help keep your injectors & fuel system clean and what not, and the cetane boost can supposedly increase MPG (nothing drastic)
The antigel additive in the cooler months help your injectors, and filters from geling and freezing.
Please correct me if I'm wrong, but this is what I'm understanding from the things that I've read. Like I've said before, I'm new to diesel truck and the 6.7. I'm all about taking care of my expensive investment.
