No worries, Brian. Sea Foam Motor Treatment is safe to leave in your oil for the life of the oil. It’s made with 100% safe petroleum ingredients and it won’t harm anything. In fact, it will continue to clean and condition as long as it’s in the oil.
Of course, we always recommend changing your oil according to your vehicle manufacturer’s instructions.
Also, we recommend adding Sea Foam 100-300 miles before you change your oil. That way, the Sea Foam has time to clean, and all the reliquefied residues/deposits can drain away with the old oil.
