Here's my UOA. 4900 miles on the oil. Ran from approximately 7,500 to 12,500 on the odometer. The copper is a bit concerning since everything else was quite normal.
Any thoughts?
Code:
KEVIN: Everything looks great in this sample from your Maxima until you get down to
copper. Normally 117 ppm would be a potential problem level of wear at brass/bronze
parts, and it's still worth watching, but this is still a pretty new engine and copper
does tend to take a while to wash out of new engines. For now, we suggest you just run
3,000-4,000 miles and check back. Copper will hopefully improve on its own. No fuel or
coolant showed up in this 5W/30 and the oil and air filters kept insolubles and silicon
low. Assuming copper drops, you'll be in good shape.
