Here is a direct comparison of iron in Tyler's truck vs mine. Guess the iron he saw the first few times is normal after all, hard to gauge that when the data isn't normalized so I did that for his truck and mine and calculated iron levels per 1000 miles.
Mine is higher at times even with the same oil (RL 5w-30) but with a much younger engine so that is expected? Mine appears to be trending down now with age.
I'm curious
@Sasquatchtdg if you hear any ticking? Anything else you can share like if you tow, idle, or use MDS etc?

Very helpful to see it like this thanks. Pretty interesting your first 5w30 redline run? Young engine but still good low wear.
If I were sasquach I might be looking at super class 0w40 oils like you did m1 perhaps with some lubeguard. Before I did I might be inclined to do a cheap oil flush, any cheap oil on walmart shelf, even use the old filter and just toss it after 50 miles and come with new filter and 0w40 near 12 cSt. Just to verify, wear is not only increasing but it is seriously increasing, hopefully something simple but I doubt any oil could stop what is coming. Something started at about 123k, usual suspect is dropping a valve or valve spring but not sure that would show up as iron? I know it is crazy to talk about 1ppm change, but chromium did tick up, something to look at next time, chromium is in a lot of those springs and rings,
see metals here. pdf Boroscope that combustion chamber see if any carbon near rings??
If it is a spring or a ring, those thin metals just have a life and nothing you can really do. Interesting is at what point do you crack it open? At least get eyes on valve springs? Save the engine perhaps.
I changed my mind, sometimes you can do something, if it is piston rings often you can rehad those if you get the carbon off them, just maybe?
