Yes, there is a certain way to "break in" a new engine.
It's based on engine building.
For most intents and purposes an engine is "broken in" when it is first started.
When we get our cars we're not breaking in the engine, we're breaking in the whole car and all it's associated moving parts.
Whether you believe, accept or not the science behind it, is really a matter of one's opinion and beliefs. That's different than not believing there IS method behind the madness.
