It is not only prudent, it would be stupid to do anything else--unless of course, one cares nothing about the cost of the vehicle and warranty and is prepared to engage with Ford on whatever level they (Ford) deem necessary since they control all aspects of said warranty and its conditions. ....
And yet very few flinch when someone (dare I say many?) here wants to "upsize" an oil filter because they perceive it's "better" ('cuz bigger always be better in Amurika, right?). OEMs and Aftermarket filter makers have specific dos and don'ts, but some pay no attention to that. But when it comes to a VERY ambiguous, tumultuous, yet-to-be-substantiated Ford lube recommendation, it's all the rage and MUST be followed?
If it's "stupid" to not follow a lube recommendation, then it's also stupid to not use the prescribed lube filter, or to run oversized tires, or ...... whatever.
Just applying the logic evenly across all things automotive.
That's not directed at you personally, but MANY here who venture willingly off the reservation when it suits their own prescribed view of OK, but then get itchy about other things if even a whiff of incorrect application is in the air. Simply put; hypocrisy.
There is no proof that CK-4 is a risk in 6.7L PSDs. The claim is seen, but the evidence is absent. Ford has rung the bell of public alert, but not proven where the fire is.
There is no proof that running an oversized filter is beneficial, yet also admittedly very little proof of risk of doing such, as seen by a bazillion examples here on BITOG.
This is why I delineated those three groups of people.
1) those who don't really care much and just wing it
2) those that strictly follow OEM criteria, but really don't know why other than they are told to do so
3) those that research deeper and make informed decisions that meet their own criteria
Until we have enough info and data to understand this Ford claim of avoiding CK-4, we can only be no further advanced than group 2. You made the right decision for you, and I would tend toward that same arena if it were mine at this point. But I'd not stop there; I'd be bugging the ever-living-manure out of Ford Cusotmer Service and Tech support, wanting proof of such. And to me this is a cautionary tale that would hurt Ford sales (at least here on BITOG; most of the world doesn't much pay attention like we do.)
One man's stupid is another man's smart.
