After reading Motoman's website regarding this subject and hearing many others opinions(from ET) on this subject, I am of the opinion that an easy break-in might not be the best answer. I for one would like to see my car with less than 10 miles on it at pickup so I can break in the engine properly(ie-the way I want to). This guy states that the first 20 miles on the engine is the most important and that in order to get a good seal on the rings, you should run it hard from the get go. Now I realize this is a very controversial area so many will have differing oprinions Im sure. I bet our cars get run pretty hard before they even make it to the US at the factory.
