For those who advocate that 'hard break-in' prevents oil consumption problems of engines that leak or burn oil, please explain what 'hard break-in' is, whether it must be done when the car is new (or if it can be accomplished at any point in a car's life), whether it involves the legal operation of a vehicle (without breaking any laws) and how you came to learn that same must be done to have a properly functioning engine with normal [read: no] oil consumption. Also, are there any notices or warnings to customers that problems will occur if a 'hard break-in' is not performed? Thank you!
