I maintain 4 6.7s, in f350 and f450. Motorcraft filters and full synthetic 5w40 are my choice. I send Blackstone oil samples periodically and change them at 8k. So far, Blackstone keeps telling me I can let the oil go longer.
Motorcraft oil filters are also known for being of great quality.
Purolator was the producer of our filters last time I checked. Motorcraft filters are surprisingly good considering how cheap they are. The bypass setup, filter media, housing and overall quality are higher than what you’d get at a fast lube place.
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.
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
Fram ultra's are fine, but their cheap filters are just that, cheap.
I do not know very many mechanics or race people who swear by wix or fram on cars that are mechanically more complex. i.e. high compression motors, vvt, etc.
Definitely use a black OEM filter, you need the correct bypass pressure and the blues are made by fram which is legit made of trash
I would NOT buy a Fram oil filter unless it was their extended life triple safety whizz bang super dooper model, the plain ones are awful.
I would move away from Fram, their oil filters are garbage even their premium stuff.
