Help your engine run smoother and last longer! Sea Foam works in fuel and oil systems to clean and lubricate critical engine areas. Made from petroleum ingredients, Sea Foam is safe and effective when used in any gasoline or diesel engine.

Pour Sea Foam in your fuel tank to clean and lubricate your entire fuel system. It works through fuel injectors and carburetors to remove harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas. Sea Foam also helps stored fuel resist evaporation, preserve ignition vapors, and prevent gum and varnish formation. When added to an engine’s oil crankcase, Sea Foam Motor Treatment cleans harmful residues and deposits that can restrict oil flow and engine lubrication. Made from petroleum ingredients, Sea Foam is safe and effective when used in all types of gasoline or diesel fuels and fuel blends and all types of motor oil, conventional and synthetic. Sea Foam does NOT contain harsh detergent or abrasive chemicals that can harm your engine or fuel system components.
