Well mine evidenced an aggregate metal wear rate of 1ppm/1000miles as seen above in post #55

How is you Vette engine wearing? Yep I know; comparing Kentucky Green Apples and Mandarin Oranges, LOL.

Unless I tear the engine down and measure how much it’s actually worn, there’s really no way to know. UOAs aren’t going to tell you how much your engine is actually wearing out.

Failure is in the pan and the filter pleats, chemical etching and micro abrasion is in the UOA.

I am not a UOA fan, but wife had a 1M mile powertrain warranty and I wanted to show no harm is being done extending OCI 50 %. on a high speed long distance commuter car. I did multiple UOA. ... Then she decided to trade up, LOL!
