Check the PCV to make sure it is operating properly. If you lost 3 quarts in 360 miles there will be signs somewhere so look around. You may want to pull a spark plug to see if it is oil fouled and also check the end of the tail pipe for oil. Look in the radiator coolant also.
If you had a oil change shop do the work are you sure they filled it up to begin with?
The oil went somewhere so all I can say is look around.
