Adding Sea Foam to gas and oil at the same time [SOLVED]

Thank you for the question, Cindi. Yes, you can add Sea Foam to your fuel tank and oil crankcase at the same time. When added to fuel, Sea Foam will work to clean fuel injectors and upper engine areas (chamber, above pistons). When added to oil, Sea Foam circulates throughout your vehicle’s oil crankcase to clean wherever motor oil flows. Hope this information is helpful!
