Valvoline premium blue extreme 5W40 Used Oil Analysis

[24Megacab]

Here are the results of the second oil sample taken from my 2024 Ram 2500 6.7 Cummins. I posted the first UOA with factory fill a few months ago. This is the second oil change, and the oil (VPBE 5W40) had 6,310 miles and 180 hours on it. I did the first oil change at 3k miles. I’m curious if the elevated potassium is related to flux or if there’s something coolant-related going on. Sodium looks fine, which would sway me slightly from the coolant theory. There is an odd ticking sound coming from the EGR cooler/turbo area, and the truck is going to the dealer Monday for this; I posted the video here.

You're not using any additives in fuel or oil?

Some of them were recently shown to have high potassium levels during virgin testing.

Nope, no additives ever. Thanks for that info though.
