I use rotella T6 synthetic and Motorcraft filters. When towing, which is most of the time, I change every 5000 miles. Be sure and change fuel filters at every oil change.
Changing the oil in the 2011-2016 (and more than likely on the 2017 as well) Powerstrokes is easier than dropping it off and picking it up from the dealership. I use Rotella t6 synthetic and change it every 15k miles.
I always go to a dealer for service on our truck...any problems, I do not want to have to argue that proper maintenance was done...too expensive to fix these newer trucks! Congratulations on your new truck...enjoy!
