Dennis: ..Copper and Silicon both read high in this sample, though neither are high enough to worry about. ..silicon may show some dirt getting past the air filter, and this could be causing some of the copper Ö
TBN 3.3, so the oil still has some life left.
After the report, I cleaned the air filter at 11 months/15,000 miles and it was filthy. Even found a cigarette butt in the airbox.

Weekday driving is 5 miles to the bus stop. Weekend driving varies from errands, driving to the beach in the summer, and fun drives in the hills and twisties. April trip to Myrtle Beach and June trip to Cape Cod (with loaded down cargo box). No track time.

TBN was only out of curiosity. Donít plan on extended drain intervals.
