Got about 500 miles now on my 2023 Chevy Silverado 3.0 Duramax and thought I'd check the oil. Noticed it was just above the high level on the dipstick. Anyone seeing the same on these from factory? Granted it was on a slight incline in my driveway but it was about 1 hour cooled from the last drive like the manual says. Any thoughts or concerns here?

A tad high, and not measured on level ground, should be nothing to be concerned about.

Yep. My 2023 GMC SIERRA SLT was above the full mark. Pickup Truck plus SUV talk did a video about this and apparently GM ships these trucks with an additional quart of oil. I keep checking my oil level and it hasn’t changed in the first 1000 miles.

When I checked my level it was a quart over.
I’ve got a couple of 100+ mile trip’s coming up in the next week or so. I’ll report back on my oil level situation. I know the LZ0 has steel pistons and a thicker steel sleeve that’s pressed fit into the aluminum block but don’t know about the piston ring material, design or looseness. This may have something to do with the extra oil for breakin.

Just want to point out that these engines do require some time to settle. So, you don't want to just shut it off and go check it. per GM, 15 minutes if it's hot is good, but a few hours is better.
Hey guy, good to see you on here! I have watched all you youtube videos and you put out great stuff. However, like I said on a comment on one of your videos is you are costing me a lot of money to keep up with your mods! LOL.

In my experience, the dealerships will put in the right oil, or at least put the right one on the invoice, but you will leave with the reading just a bit over the top mark. I believe this is due to them giving it a certain time to drain and then just putting in a prescribed amount of new oil. Unless it's significantly over the max mark I think you're good to go.
