Can't figure out why Titanium is the same in both UOA's shown. The old UOA you had Mobil Super 5000, and it should have been about 30 ppm, per http://www.pqiamerica.com/ExxonMobilSuper5000.htm ...
Then, you use M1 High Mileage 50% in the latest UOA, and Titanium turns out predictably to be 14 ppm, expected.

What part of the UOA I posted gives you that impression?

Irrelevant. You said it's not effective. What part of the last UOA says the oil is ineffective? Air filtration problems can't make oil seem more effective. Only less.
Mixing oils? OP has 219k on this unit. Hardly a big deal. I'm assuming the sample date was 1-5-16, not the one shown as 1-5-15. How long was the oil in use - months? Thanks for posting.

How would a UOA be able to give such an impression in the first place?
