Sea Foam

About Sea Foam: America's Trusted Engine Treatment Brand

Since 1942, Sea Foam has been one of the most respected names in automotive chemical treatments. Founded on a simple but powerful idea — that a single, petroleum-based formula could clean and protect engines from the inside out — Sea Foam has spent over eight decades refining products that mechanics and everyday drivers alike have come to rely on. What started as a solution for gummed-up carburetors in fishing boat motors has grown into a comprehensive line of treatments for cars, trucks, motorcycles, lawn equipment, boats, and more.

Unlike many chemical brands that rely on harsh detergents or synthetic solvents, Sea Foam's formulas are made entirely from petroleum-based ingredients, making them safe for use in virtually every type of gasoline and diesel engine. This philosophy of safe, effective chemistry has earned Sea Foam a loyal following among professional technicians and DIY enthusiasts who want results without risking engine damage.

What Sea Foam Makes

Sea Foam's product lineup covers the most critical areas of engine health. Their flagship product — the iconic Sea Foam Motor Treatment — works as both a fuel additive and an engine cleaner, dissolving varnish, gum, and carbon deposits that accumulate in fuel systems and intake passages over time. Regular use helps restore lost power, improve fuel economy, and reduce rough idling caused by dirty injectors or clogged carburetors.

For enthusiasts preparing engines for storage or seasonal use, Sea Foam offers fuel additives and storage kits designed to stabilize fuel, prevent gum formation, and keep fuel systems fresh during long periods of inactivity. Whether you're winterizing a lawn mower, a snowmobile, or a classic car, these products help ensure a clean, reliable startup when the season returns.

Sea Foam's engine tune-up, carburetor, choke, and carbon cleaner products tackle stubborn deposits that accumulate in throttle bodies, intake valves, and combustion chambers. Their aerosol spray cleaners are a favorite for quick, targeted cleaning without full disassembly — a go-to for mechanics doing preventive maintenance.

Beyond the fuel system, Sea Foam produces a power steering fluid treatment that conditions seals and quiets noisy power steering pumps, as well as an engine oil additive that liquefies crankcase deposits and helps lubricate upper cylinder components. These products round out Sea Foam's mission to address every major fluid system in the modern vehicle.
