Good question, Blake. You can leave the Sea Foam in the oil for the entire oil interval, as it won’t “lose” its cleaning and lubricating properties. Sometimes it takes a few oil changes to progressively clean up an oil system. Sea Foam in oil will clean residues and deposits in the crankcase and oil passageways. We like to recommend adding Sea Foam 100-300 miles before you change your oil so you can drain away all the reliquified deposits with the old oil. But you can leave it in for the entire oil interval if you’d like.
