You can leave Sea Foam Motor Treatment in there for the life of the oil (until your next oil change). It won’t hurt anything to leave it in for a long period of time.

That said, we recommend adding Sea Foam to your oil about 100-300 miles before your next oil change. That gives it time to clean and allows the residues that the Sea Foam cleaned to be drained away with the old oil.
