Seems like some haven't done any changes on the M2 and that's making me more nervous than just doing it myself...

Yes, I had my oil tested by Blackstone. I changed at 1200, 5000 and 10,000 with a sample from the last change sent in. All looks good so I'm going to try 7000 mile intervals. I do track the car, six days so far this year. I'm going to stick with 5w30 until I can get a good oil temp measurement.
