Low mile Maverick, 5600 mi on oil. It looks like I expected, although the copper seems very high? Haven't seen other UOAs with that high, where would it be coming from? Bearings? I drive mostly freeway, and the mpg remains around 45. It does everything I want, quite happy with this little truck. Oil filter was MC fl420s, tossed it but will open the next one.

I'd say it's from bearings but I also wouldn't be too worried unless the trend continues. I recommend changing oil at 5,000 miles and resampling. If there's no change notify your dealer and keep these UOA documents in case there is a future problem.

The engine is still wearing in. You'll see wear metals going down each oil sample. My engine is at 25k mikes and it's still not worn in 100%. As long as wear metals trend down, you are good to go.
Copper level is a second drain signature. It's residual from assembly products. Initial drain would have been over 100 ppm. 4-8 ppm would be typical of third.

Keep it at this 6k interval until Si comes down a bit. Perhaps another drain or two. Post back results when you can.

I would recommend a filter where unfiltered oil doesn't leak past the bypass valve, The Purolator Boss or One filter are very well made filters.
Look like very good break in numbers to me.
I would change oil again after 3,000 miles and then go 5,000 miles and retest with oil analysis. Wear metals and break-in time is the issue here. Wear should lower and stabilize after 20,000 miles.
On a new vehicle, my preferred OCI interval is first oil change at 500 miles, then 1,500 miles, then 3,000 miles, then 5,000 miles then 10,000 miles. Then test, then adjust OCI after analysis whether you prefer 5,000/7,500/10k or more. Driving habits, oil preferences, and oil analysis will get you where you want to be.
I would agree with Reloader on this one. Purolator Boss has been tested against many other filters. You can see the test results on Brand Ranks on YouTube

Wow.
I change the new vehicle oil at 3k - then every 3k thereafter.
My M.O. since 1970 and that's a ton of DIY oil changes, for both me and you.
Enjoy doing them..... I sure do. But at 73, it's getting tough crawling under and then slide back out. Not sure how many more I will do. When I quit, I'll take my own oil to the Valvoline Center near me. I trust their work, for they do oil changes (and more) for some friends and relatives of my community.
I think there are a lot of good ways to get break-in metals out so I think we are doing similar thing. I am just a proponent of going a touch overkill in the first 10k miles on a brand new engine. I’ve got 2 Honda’s over 300,000 miles and 2 Subaru’s at/over 30,000 miles. I do a decent amount of analysis and results that I see that the break-in wear metals go/settle down quickly. If I had an oil filter that could filter 99% at 10 microns… then maybe I would stretch out that initial OCI interval … but there isn’t such a filter.

Body and engine parts are digitally cut nowadays. Most new vehicles today don;t even contain a rattle and some of the curves on the outside body detail how close manufacturers can get to a superb fit. Engines don't shed metals anywhere near what they used to, as a result.
If some folks here are getting an abundance of metals at their first couple oil changes, I sure wouldn't buy that same engine again. There's poor craftsmanship abound. But in these days of AI, it doesn't need to be that way. That's a poorly run engine factory, if metals are abundant.

2.5 years ago my Maverick Hybrid started its life with 2K, 6K, 12K and each 7,000 or so since then OCI's. Approaching 28K and it uses no/minute amounts of oil. My last change a few weeks ago the oil at 7K of use, looked amazing and still had lubricity between the fingers.
I don't think machining was the issue (at least it wasn't in the Hyundai/Kia and Toyota Engines). It was an issue with getting all the metal chips out after machining. Whether it was mostly procedure or block design I can't say. Regardless the bearings didn't like it much.
