Purchased 2010 E92 M3 with 82K miles on last day of Sept 2018, and from Carfax records, could approximate when the last oil change was reportedly done.

Sent in my first oil analysis after nearly 5000 miles since the previous owner's oil change, because I wanted to know. I had asked about possibly mixing 10w60 and 0w40 as I'm in Chicago, it's 21F outside now and takes forever for the car to warm up, keeping it between 2000 - 3000 rpm until it comes to temp. Seems odd that they tell me it's a nice first report, but to watch copper levels closely because its 2x the average value already? I'm thinking one more lab report, and change out RB before November next year if it looks the same, but immediately if it looks like a worsening trend?
