Whatever the dealer puts in it and Motorcraft filter. Usually get coupons for multipoint inspection and sometimes even tire rotation.

For oil filters I use Baldwin PN # BT349 on my 6.4.

CJ4 and PLUS oils are allowed much more ZDDP. Not saying that if you buy a CJ4 oil you will get that, or if it does have a high ppm of ZDDP that its quality is better than an SN oil. We are allowed and take advantage of this. Ive done OA on my personal Ecoboost and at least our package makes a difference in fuel dilution. Also noticed its viscosity held up with the same fuel dilution levels. Granted, Im of the opinion that a brand new car shouldn't have 5% fuel in the oil at 5k miles. But the dealer disagrees and says that's normal.... But what do I know.

Rotella T6 here since new. Oil analysis always comes back great with .5% fuel. Motorcraft filters as well.
