After an oil change, does the engine/system needs a break-in period in order to return the milage to 'normal'?

While I am sure it is not a big deal the car is not spec'ed for 5W30, the Oil filler and manual clearly state 5W20 or 0W20, I would go make the dealer swap it out, unless they told you ahead of time. Ido my own oil for years becasue I don't trust oil change places, they either put in too much or too little or use the wrong weight oil.
