2022 Silverado 2500HD, 6.6l gas
OCI: 5k miles
Out: AC Delco 5w30, AC Delco PF63 (free dealer oil change)
In: Quaker State Full Synthetic 5w30, Napa Gold 100255 Filter
I had placed magnets on the filter during this run. I was pleasantly surprised with how little they accumulated. This was my last Napa Gold filter in my stash. Going forward I will be using the PF63s. Down to only 8 qts of Quaker State Full Synthetic, then I will be switching to Mobil 1. I have been using Quaker State Full Synthetic or Quaker State Ultimate Durability for years with great results, but I am struggling to find it stock locally. I can always find Mobil 1.
