Add Sea Foam Motor Treatment to every tank of marine engine fuel – Just pour it in!


  • Sea Foam Motor Treatment works to dissolve and clean fuel deposits and sticky residues from gas and diesel injectors, carburetors, and combustion chambers.
  • Sea Foam helps to stabilize stored fuel for up to two years by resisting evaporation, preserving ignition vapors, and preventing the formation of gum and varnish.
  • Sea Foam provides high-temp upper cylinder lubricity and helps to protect the entire fuel system from dry out, wear and corrosion.
  • Sea Foam only contains petroleum-based ingredients. It does NOT have harsh detergent or abrasive chemicals that can harm your engine. The more you add to fuel, the better it cleans
