I had a post break-in oil change done, and had the dealership pull a sample. The sample was sent to Blackstone Labs. I'll continue to pull samples with every oil change, and over the years, I'll post the results here.
Feel free to add your own results if you get your oil checked.

I own no garage queens. If it's in my driveway, it's been ridden hard and put away wet. ...and now, with a light crust of Maine road salt.
