I've reached out to Amsoil with the report and to get their input. Since I've only been buying one quart of various the DexosD oils for VOA I had already dumped the rest of the quart for disposal. I do still have the bottle so I was able to provide the batch number to Amsoil so it's not a total...
Figured I'd start a new thread since I changed oils on my '24 LZ0. This is the first UOA of the Mobil 1 ESP X2 0W-20. Iron is still coming down and is now to 7.45 ppm/1k. They note Boron is lower than normal compared to the VOA I sent in of the Mobil 1 with the last UOA of the ACDelco. I'm...
Here's the latest analysis back. This is the last batch of the ACDelco DexosD and I have switched to the Mobil 1 ESP X2 0w-20. Iron is down to 8.5 ppm/1k miles, everything else looks nominal. I also used the spare quart of AC Delco I keep in the truck to pull a baseline sample and the rest to...
I've had the Banks iDash in my '24 3.0L for most of it's life to track regens and the only thing I did to reduce the fuel dilution from my first UOA was let it idle a lot less. Mainly I quit using the remote start to cool off/warm up the cab and my fuel dilution has fallen to below 2.0% since...
Here's the latest analysis back. Still went with the ACDelco Dexos D and another UPF66R filter for this change. Iron is still hovering in the low 9.X ppm/1k miles, everything else looks nominal.

Just finished changing the oil to the last of the AC Delco Dexos D I had and switched from the standard AC Delco filter to the AC Delco Gold filter. I’ll get the sample shipped tomorrow and post the results as soon as I have them.

With my mileage intervals on the oil, it would put my iron content of the factory fill at 13.3 ppm/1k miles and the second fill at 9.8 ppm/1k miles. So the wear has lessened over time.
This is the first two oil analyses I've done on my 2024 GMC Sierra Duramax 3.0L LZ0 engine. Both times I've replaced the oil and filter with the ACDelco Dexos D 0W-20 oil and the PF66 filter. First sample was pulled at 5192 miles from the factory fill and the second at 12141 miles with 6949...
