Since the lead is low, the copper probably came from the bushings/thrust washers. It could be some transient effect or even some measurement error.

Yeah, I'm a little concerned about conventional for two-year OCIs.

Note that the universal averages shown in the last column of the Blackstone report are for 2,600 miles. Since I ran for twice the mileage and close to two years, my numbers are still a lot better than the universal averages.

Another choice is PPPP Euro 5W-40 A3/B4/SN. It's expensive though.

Considering lab measuring error of a few ppm you are barely seeing any wear. Certainly nothing to worry about.
Was the engine oil up to temp or cold. I would trust a cold reading a bit less and probably try the dino on a slightly shorter interval.

I don't think "Delo XLE 5W-40 CK-4/SN PLUS full synthetic" exists. There is Delo XSP 5W-40 syn, and there is Delo XLE 15W-40 blend. I wouldn't mind if you tried these 2, but it's time to use the Delvac before the jug disintegrates.

Driven for 20 miles on the freeway and hot.

My typo. It's Delo XSP 5W-40 CK-4/SN PLUS full synthetic. Yes, I'm also aware of the Delo XLE 15W-40 CK-4/SN PLUS synthetic blend. Delvac 15W-40 CJ-4/SM is about eight-years-old. No SN PLUS and Allison TES-439 on the SDE, while the XLE and XSP have them.

There is no moly in the XSP and XLE. SDE seems to have a better additive package. I didn't see much difference in wear metals in UOAs for conventional and synthetic HDEOs.

The next OCI will be M1 EP 0W-20 SN PLUS and FU XG3600 oil filter.

Which container is your TGMO? Quart or can?

Quart is the only container here other than the 55-gallon drum.
