I always change out the factory oil at around 1,000 or less. Just want to get any of the particles from the manufacturing process out of there. On my new 2022 Sierra which I am taking delivery of this week with the 3.0 I will follow the same pattern I have on my other vehicles. I never pay attention to what the oil life monitor says and I will change every 5K using either the AC Delco Dexos or the Mobil 1 Dexos compatible oil with either the AC or Mobil 1 filter. Looks like oil changes on this engine a snap compared to my 2017 Ram which was always a guaranteed mess with the way they mounted the filter on the Hemi. To me clean high quality oil is cheap insurance.
