    At your next oil and oil filter change replace one quart of the engine oil with one quart of marvel's mystery oil. The marvel's is supposed to clean and lubricate the engine internally. If you have a while before your oil change is due, replace the oil filter, and top the oil off with no more than one quart of the marvel's mystery oil. Do follow the instructions on the marvel's back label.
