No, the oil placed in the car when built is the same oil that should be used for its entire life. It is changed after 1200 miles, in order to remove metal shavings, etc., resulting from break-in.
Engines tend to "loosen up" over time, and it's not unusual for them to have more power and somewhat better economy after a few thousand miles.
However, special break-in oils are no longer used in modern engines.
