What are your thoughts on engine break-in? Some say follow http://www.mototuneusa.com/break_in_secrets.htm method, which is drive it like you stole it the first 20 miles. Others say vary the rpm's the first 600 miles and some just follow the manual which says take it easy the first few hundred miles. I've posted a thread on another forum and the consensus their was that it doesn't matter. Some have broken in their cars easy and have had no problems, other hard and the same thing. I think it's safe to say that cars today don't need sophisticated break-ins due to modern technology. Thoughts?
