Premium Plus is gonna give you plenty of low temperature help.
gotcha. Is that an issue common for these vans? Or just a mileage consideration?
Should I switch between 0w/5w in winter/summer? Van is parked outside.

I would stick to 5W20 Premium Plus and use successive UOAs to probably get out to 15k mile/1 year OCIs.
It's a shame that you don't have two reports from the same lab. Wear metal appear to be higher but may not be due to differences in procedures or equipment utilized by the respective labs.
You don’t have your location listed, but here’s some:
Polaris/OAI- Indianapolis
WearCheck- North Carolina
lots of Napa labs
Caterpillar labs
TestOil- SW Ohio ($$)
Others are around but staying with the above will ensure results you can have confidence in. My HPL was thick, but that was expected. 1.5cSt increase in 14.4k is measurable but not very significant.
Aluminum is a touch higher than I would expect, but it’s not a point to worry. I don’t recall the exact breakdown, but IIRC HPL Dave has told us one of the components shows up with a few ppm of Al in OAs, and it’s not from “wear”. It’s in the add pack.
Is the TBN 10.1 on this sample? Or am I reading it wrong?
Al is definitely higher on my sample comparatively. Was it premium plus passenger HPL you sampled?
Premium plus 0w-20. 10.1 on the D4739. U maybe using a different TBN test.
I don't trust the numbers on BSLabs' reports, and in this case that means I think they probably screwed up the UOA in the OP. Was it ever re-run? They've screwed so many things up so many times for so long...
Let's say, for the sake of discussion, all the numbers in the UOA in the OP are accurate. What then is the proposed theory of operation to explain the super-high viscosity shift in only 5k, and why did that 'go away' in the second UOA?
The second UOA shows higher iron and aluminum than I would expect. However, if it's an un-muzzled VCM, then maybe they're about in line.
It seems like you're happy with HPL's product, and the second UOA doesn't scream any cause(s) for concern.

They never re-ran the initial sample. Given the info I was given about BS, I went another direction for testing after them.
The van is muzzled, so no VCM to speak of. I am hoping this leads to additional engine life compared to VCM being active.
