Motorcraft filters are made by Purolator. It's been my experience that Motorcraft filters work perfectly fine. I used Motorcraft oil as well until I switched to full synthetic.
Owner reviews for oil filter
Ran whatever fram filter they had. Regular, tough guard and the synthetic. Over 500,000 km doing synthetic oil and a fram filter every 15,000km. It’s still going. That’s over 40 fram filters, never had a problem
wenn möglich Ölwechsel bei Mac Oil durchführen lassen, kostet je nach benötigtem Shell MotorÖl zwischen 50 und 80€ inkl. mann Ölfilter und zurücksetzen des Service, plus eintrag ins Scheckheft. dauert ca. 15 min reine Arbeitszeit und kann im Auto sitzen bleiben. unschlagbares Konzept.
I use a FRAM filter for my civic.
A good oil filter (I say BMW as I found they fit the tightest, best seal compared to even the MANN/MAHL filters specific to my N20)
Oem filter or wix WL10078. For oil pennzoil platinum or ultra platinum 5w30 (whichever is cheaper).
TRD Pro filters or nothing in my ‘15 TRD. Full synthetic media/99% efficiency at 20 microns, wire mesh backed media, steel end caps, steel center core, silicone end gaskets and filter housing gaskets. All for $13 bucks on eBay. But to the op, I ran one for a engine flush I did when it turned over 100,000 miles. Held up pretty good for only 3,000 miles. I’d say it’s one of the best the shelf options for the price. Hard to pay $20 plus for the wix with all that polish plastic and I wouldn’t put a OEM filter in my zero turn let alone my truck. Talk about absolute garbage; semi synthetic media, no end caps, no wire mesh, just a rolled over pleats super glued together at the ends.
That kind of looks like it's coming from the oil filter cap. Did you use an oe filter and oring? I had the o-ring leak under boost when I used a mobile one filter with a defective ring. It made a mess sort of like that.
I dont think valvoline is using a quality filter with the required oil.
Those KN filters are so tiny and I have had one break in my NA Ford Falcon so I don't use them any more.
