This is surprising, especially with the increased fuel mileage this fill seemed to have brought. The mystery here is whether the new AZO formulation caused the increased wear metals, or something else...

Blackstone Labs; Harry, Something changed between December and now-lead showed up for the first time in
recent history and shows an uptick in the amount of bearing wear. It's just barely outside the average
range, but the deviation from the norm of zero is worth noting.Potassium and Sodium also increased
and could show a small coolant leak, which could be related to the bearing wear. If it is coolant, it's
not a lot and you probably wouldn't even notice a drop in the reservoir.Silicon bumped up some, probably
from dirt or sealers. The TBN is fine at 3.3 and the Particle count was 18/17/14.
