I was told at the factory to keep the RPMs under 3K for the first 500 km. I had planned on doing a more aggressive break-in and hit 150 mph 5 hours later on the Autobahn. I did vary RPMs a lot and did a lot of engine braking and didn't go completely to redline. I'm still burning a bit of oil, especially after driving hard, hopefully it'll calm down with more miles (currently 1260).
