Gladly. Judging by your response, I can guess that you haven't ever opened one of these.
In fact, you can read it for yourself since my pictures are barely readable:

Yes, I am aware that is only 2007 model year. But it is the exact same as what I currently hold in my hand. The core manual itself has no recommendation outside of that scheduled maintenance guide. In fact, it refers to the use of the linked guide for service intervals. Please be sure to read
all the pages. Oh and according to that guide, normal conditions are 5000 miles and severe are 3000 mile intervals. I was a little off, but it is a far cry from 10,000 mile intervals.
Remind me to catch my boss sometime next week and have him take a picture of the oil window sticker, if you still want to see it.
As far as ever purchasing an analysis, I have not purchased one. I may consider it in the future, but the 3000 mile interval seems to be the changing point for my oil as I see it. I'm not fond of waiting until my oil is black molasses to change it.
Happy Thanksgiving,
Dave
