That oil starts out at 14.65 cST, and ended up at 11.5 cST, which works out out to around 8% fuel dilution. This assumes no shear-thinning of the oil. A 15W-40 won't shear-thin all that much, so I'm guessing fuel dilution would still be around 5-7%.
So even without the MMO, dilution is probably higher than normal. If you did a lot of cold idling while troubleshooting, that might explain it.
The sodium is probably from salt water, maybe getting in through the air intake or even the fuel system. The elevated wear metals could be from corrosive wear.
