Many thanks to Terry Dyson!!!
This UOA may be of interest to some in that namely:
1.) Air filter was cheapo STP put in fresh for this run of oil. The AF saw the exact same number of miles that the oil did.
2.) Honda Filtech Inc. oil filter had been left on from previous OCI, so filter had a total of 10,322 miles on when sample was taken.
No make up oil added. At least one bottle of Techron (poured into empty tank then filled with 11 gals. of fuel).
Fuel is still an issue, no surprise.
I have a K&N oil filter spun on and will follow the same process.
I purposefully poured in my last stash of MC as this will be the last UOA the van will see for quite some time. I am confident that MC or better will work well with this type of interval. OLM btw was only down to 30%, based on all the UOA history, I will stick with about a 5K drain which I feel is perfect.

Note: I noticed that the site I used to host my images is not up, I will have to investigate. Once back online, I will post new image with all UOA history in nice format.
