Looks likle would be expected - the 40W Euro oils all seem to drop down into the 11s KV100 after even v. short runs in turbo engines like this one. Wear metals at ~5K are now basically background values from all the early oil changing. That factory fill looks good with all that moly and boron. I don't buy the comments about the bit of 20W left in there, it has to be such a tiny amount vs. the new oil fill volume....just a bit of fuel and the normal bit of shearing. You could remove the visosity data from your UOAs and say you used basically any oil you want and the data would make sense...you won't see any meaningful difference in the wear metals form the 20W to the 40W is my thought.
