You can run Rotella, but IMO there are better oils.
The list has already been posted, as well as the recommendation for Valvoline Premium Blue, which I second. Good oil, cheap enough when on sale at NAPA or Menards.
The topic of PowerStroke oils has been bashed and thrashed in many forms here.
5w vs 15w, 30 vs 40, should I run uber cash 99.5% PAO or can I dump my 1.35 a gallon closeout oil in?
Ford has never done well with fluid recommendations. I swear their goal is to confuse every owner of a Ford so much they return to the dealer where even most of them dump whatever cheap bulk in and send it on down the highway.
I have a 2016, and am running that 1.35 a gallon Peak 15w40 semi-syn CJ-4 in mine. The engine and I are both happy.
My BIL has a 2012 currently running Harvest King 15w40 from Rural King at 11.99 for 2 gallons.
There is still CJ-4 out there, go get a few gallons, change it every once in a while, and drive. There are more than a few local 6.7's here on unapproved Mobil Delvac and Delo that haven't stopped yet as well. One thing we all seem to agree on in the group is to run a Donaldson P502503 filter though.
OT, but is anyone looking forward to the redesign of the PSD for 2020? 1015 foot pounds of torque is impresssive.
