Seafoam Motor Treatment

Sea Foam Motor Treatment is a trusted fuel and oil additive formulated to clean, lubricate, and protect gasoline and diesel engines. Made from 100% petroleum-based ingredients, it works throughout the fuel and crankcase systems to dissolve gum, varnish, carbon, and other harmful deposits that can reduce engine performance. Suitable for automotive, marine, powersports, and small engine applications, Sea Foam helps maintain smoother operation while supporting long-term engine reliability.

Safe for both 2-stroke and 4-stroke engines, Sea Foam also stabilizes fuel during storage to help prevent degradation and make seasonal equipment easier to start. Simply add it to the fuel tank or crankcase as part of routine maintenance to keep critical engine components clean and protected.
