New owner here. I definitely have some questions about stuff since this is my first new diesel truck. I did previously own a 6.0 PSD, but I bought that truck used.

  1. Break in recommendations... What is needed to get good ring seating in these motors? Gentle driving? Hard driving during break in? I know torque management is a thing, and you cant jut hammer it like a gasser, so what’s best practice?
  2. First oil change/OCI? I’ve always changed out my factory oil right around 500 miles on my gassers, just to get any break in oil, assembly lube and initial wear metals out. After that what’s everyone’s OCI on say Rotella synthetic blend or Valvoline blue?
  3. 68RFE I’m hearing as long as you’re not tuned These trannys are pretty solid. I don’t plan on doing any tuning or deleting, at least within powertrain warranty period. How often should I do a drain and fill and filter change?
  4. CP4.2 Should this pump be considered a maintenance item like a timing belt? Say if you do a 75K service interval on this pump would that save any potential grenading of the fuel system? What about diesel kleen or another additive? I live in the south, so fuel gelling in cold months is not a concern.

I want (have) to run this truck trouble free for as long as possible. I will be doing the vast majority of my own basic maintenance. Fluid and filter changes, brakes, etc. So real world (not owners manual) intervals would be greatly appreciated! TIA
