Some people think you should push your car really hard initially to seal the rings. Some say you should treat it delicately and vary the RPM ranges. Some say all the breaking isn't necessary because the factory machined clearances are so close compared to cars even 10, 15 years ago.
After a ton of research I don't believe anyone knows for sure what to do when you first get a car.
