I have been running regular Wix 57060 or Mobil m113 filters in my 6.4 with Mobil 0w40 for the last 45k miles. I was seeing 25 psi at hot idle, in gear.
Made the switch to the Royal Purple 10-48 filter, now I see 27psi at hot idle throughout the OCI. After reading through here I am going to make the switch to a bigger filter like the 20-820 or the Fram FE2 and see what numbers I get with that.
What are you folks seeing in your 6.4 trucks for oil pressure and what combo oil/filter are you using?
Edit to add: I got to talk with a guy who was making a delivery from Alabama, pulling a medium size trailer with *230 degree water and oil temps when he pulled in had 34psi at idle. This was with 180k on a 2019 6.4. Im not worried about my pressure, but I feel shorted when hard used trucks are giving 7-8lbs more than my well kept piece.
