Wear metals look great in this latest sample from your Traverse. Iron is all the way down to just 10 ppm, and
other metals don't show signs of poorly wearing parts. If your engine is having any mechanical problems, the evidence
isn't showing up in the used oil. The viscosity was spot on for a 5W/30, and no contamination from dirt, fuel, water, or
coolant was present. The TBN was good at 2.1, and the TAN was 6.3 - some acidity. You could go up to 7,500 miles on
the next fill. Iron might go up, but other metals should remain relatively steady. Give it a shot and check back.
