Most car manufacturers test their engine at the factory, they run it hard for a few minutes, but in no way do they do the full break in. All break-in procedures are precautionary, its not require. If you dont follow it, it doesnt mean your engine will fall apart. The break-in procedures is there to ensure all new parts wear slowly into its operational state.
