I would like to use Sea Foam Motor Treatment in both my fuel tank and in my oil crankcase. Is it okay to add to the fuel and the oil at the same time?

Yes, Sea Foam will work safely in fuel at the same time it is working in your motor oil. In fuel, Sea Foam works to clean and lubricate through fuel passageways and combustion areas. In your crankcase, Sea Foam works to dissolve heavier oil residues and deposits back into liquid form so everything drains when you change your oil and filter.
