To me, some of the wear metals look higher than they should be for this mileage (comparing to a UOA I had done on my 2008 Sienna in January of '19 using Mobil 1 5W-30 for 6,000 miles but that vehicle is 90% highway miles commuting to and from work).
Both the 2008 and the 2016 Sienna's employ Toyota's 2GR-FE 3.5 liter V6.
Link to UOA in January of last year for my DD 2008:
This OCI was mostly shuttling kids to and from school, and most daily trips were 15 miles or less with one long haul of about 1000 miles over about a week in July of 2020 to see family out of state.
This is the first UOA on the vehicle since it came into our possession in August of 2019 (with 102,000 miles). I performed an oil change on it shortly after we purchased it and put in the Mobil 1 EP and used a Mobil 1 M1C-251A oil filter.
Base number still looks excellent at 4.4, and I would venture a guess that this could have easily ran the full 15,000 miles without hesitation.
Any thoughts on the Metals, specifically Iron and Copper in this report? Thanks!

Daily driven short trips less than 6 miles each direction as kid hauler. Road trip at least 2X a year 1,000-2,000 miles round trip. It does have some Piston Slap when cold for as long as I can remember and definitely hasn't worsened in the last 3+ years that we've owned it. Wear number are...
