I keep on remembering Truck Central who is almost at 250k miles with 2000 idle hours running PUP 5w-20 and changing when the oil indicator tells him too, lots of heavy towing thrown in as well. No issues to date. Have to admit reports like the one above confirm my belief that you either get a bad lifter from the factory or you don't and high quality oils can only mitigate that so much.
It's not going to change my belief that we absolutely should still be running oils like HPL/Redline/Mobil 1 0w-40.
@Sasquatchtdg how long were you running Redline 5w-30? Looks like your iron started climbing right after 100k miles? Given the consistency in the other ingredients it looks like you were running this since at least 84k miles?
