LONG time reader and finally found a reason to join and contribute!
(I’ve always been able to find what I’m looking for) I can’t find any LM2 results or any of the AC DELCO Dexos D oil reports.

Here’s my 700 mile factory fill UOA. Should be AC delco 0w20 light duty diesel oil.
I’ll run to 5000 and send another. May try ESPx2 as well.

Keep us posted on how the M1 ESPx2 does....I just picked up 2021 Sierra with the LM2 and I filled with the M1.
Will do. You’ll love the engine. I have 2k more miles to do and I’ll sample and send it in.

Frankly I may sample and not drain and wait for results.
Another high iron and I’m going to run esp 5w30 or 0w30. Frankly I would go delo fa-4 5w30 or Castrol C3 but it’ll be easier to keep a proper paper trail if I run run the esp line.
