2022 Silverado 5.3L 25k mi; Mobil1 AFE 0W-20 5.1k mi

First time UOA, not sure if I'll do another, but maybe at 50,000. I'm planning for 5,000mi or (6) months OCI. Besides using the data to verify running longer OCIs, what would the average user do with the data?

A few things here, but 1st, thanks for the UOA!

If you are going to do 5000-mile OCI's or change the Oil every 6 months, there really is not a need for a UOA. If you ever do a UOA again at least get a TBN and TAN Number. I would also recommend using Amsoil's UOA Service, I think it is called Oil Analyzers, and there is also some Speed Something, both of these are better than Blackstone.

Thanks for sharing your Silverado's UOA. Still may be some higher metals from break-in still. Overall, you plan to stick with AFE?

M1 AFE is such a good oil. 10k+ OCI’s easy.

Not the best first uoa but not the worst. How many oil changes has this engine had before this one?

You found a good combination, carry on with your plan.

I believe four, but I bought used so no sure way of telling.

yes for now, but I have purchased some Kirkland brand 0W-20 when it was on sale so that will go in next

I would maybe bump up to 5w 30 or 5w 40
If it's OK for a 6.2 its ok for you
