No, you do not need to drain the oil after adding Sea Foam Motor Treatment. You can safely leave it in the oil crankcase as long as you’d like.
However, we recommend adding Sea Foam to the oil about 100-300 miles before your next oil change. That way the Sea Foam has time to clean and all the dirty oil and reliquefied deposits can be drained away when you change the oil.
