my buddy has E46 M3 that burns no oil at all (or seemingly none).
He broke it in by respecting the revs quoted in the owners manual and by doing the rest of it the right way... that is to say he made sure to load up the engine (no full throttle, but good amount of throttle) and to keep changing engine speeds. Ever heard of an E46 M3 that doesn't drink oil? well his doesn't and its the only one I've heard of that is like this.
I broke in my sport bike the same way and it is faster than other examples of the same bike (raced guys that were smaller than me on the same year and model bike and beat them... my bike seems to pull harder in the higher revs than others) and it also burns zero oil.
