Maybe overkill but I dont like running break in oil all that long.. Changed it at about 1500 miles or a little over. Went with PUP 0w-20 and a WiX XP filter. Noticed not long after I got clatter on cold starts and the engine just seems louder. Oil pressure is fine. Clatter is only on cold starts and not every time. Goes away after a few seconds. My buddies 2022 is much quieter than mine. Tempted to do the Redline 5w-30 and Royal Purple 20-820 filter. My worry is warranty since the truck is new. I have a Royal purple filter or Mopar SRT filter already lined up for next change.. Just not sure on oil or why I got clatter after changing from the original oil. I spoke with Redline who told me warranty could be an issue running their oil even if correct viscosity as it doesn't meet the stamped cert the manual calls for.
