It's too late for me now, but I'm curious if anyone has something specific re: the best way to break-in a new engine? The oil and oil change inerval has been amply discussed- but I have seen little on how to actually break the engine in, in terms of speed and load and number of miles at what speed, etc. Tangentially, is there a better season of the year /an ideal climate in which to break a new engine in? ie., is it better to do it at the North Pole, at the Equator, or somewhere in between??
