This seems to be the sensible response last time the subject was brought up. The best case scenario you save a few bucks annually on filters. The risk is you mess up a fuel system that dealers are chomping at the bit to charge you 10 to 15k to repair.

They are re-branded PTC (power train components) filters, Doc's is vague on specs (which in fairness a lot of filter manufacturers are, including Motorcraft) because they are simply a middleman with a good social media and marketing group. They don't make anything.

They lost me when they could provide any data on the water stripping efficiency of their water separator when I inquired, kept saying the filter is 3 microns but particulate filtration and water separation are two totally different animals. Different ISO and SAE tests, they couldn't understand that.

I bought the Doc kit last year. My oil filter wrench did not
fit the filtet ,its fits the ford fine so it went in the garbage.
Now the way i look at it ,it's a 20,000 motor so i don't think i will cheep out on filters. It's not worth the risk

OEM all the way, if it's good enough for the warranty, its good enough for the life of it.
