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.
$5 Motorcraft oil filter from Rock Auto
Try to source OEM Hyundai oil filter though. I've heard that ticking before with non-OE filters, and regardless of what shops tell you the OE filter can make a difference.
I purchased 10 pack OEM hyundai filter on amazon for $37. still have some left. 5 qt oil is $15 on sale at costco.
OEM oil filter is required in Hyundai or they will shut down and leave no codes in OBD2
72 dollars at my dealer, 120 everywhere else.
I've seen those leaking at the crimp now multiple times.
