Sea Foam Motor Tune Up Treatment 1Gal (128 Oz). SF-128. SEA FOAM Motor Treatment is a 100% pure petroleum product that safely and effectively cleans internal fuel and oil system components, helping your gasoline or diesel engine run cleaner and more efficiently. SEA FOAM is an EPA-registered product, and will not harm engine components, seals, gaskets, catalytic converters or oxygen sensors.

SEA FOAM liquifies gum and varnish deposits or internal engine components, removing carbon deposits, freeing sticky valve lifters and rings curing rough idle, pinging and hesitation problems. By using SEA FOAM to eliminate varnish and carbon buildup, mechanics can more accurately diagnose mechanical problems that may exist. That is why Sea Foam has been so popular with professional mechanics for over 65 years.

As a fuel system additive, Sea Foam will clean fuel injectors, clean carbon, gum and varnish deposits, add lubricity to fuel, stabilize fuel for 2 years and control moisture.

As an oil system additive, Sea Foam controls moisture, gum, varnish and residue deposits.

How to use Sea Foam in Tune-Up of Small 4 Cycle Carbureted Engine Lawn Mowers, Tillers, Edgers, Snowblowers, etc.

  • 1. Start engine. If engine will not start, check spark and compression. If engine has spark and compression, pour a small amount up to 1/2 ounce into the carburetor throat. SEA FOAM will act as starting fulid and will start the engine unless there is a mechanical or electrical problem. With engine warm, keep on high idle and slowly pour one ounce through carburetor throat. Make sure exhaust is well ventilated when using in the carburetor as fumes will be extreme for a short time.
  • 2. Pour 1/2 ounce to one ounce into small fuel tank and oil crackcase.
  • 3. Immediate Results: Same as for large 4 cycle Autos, Trucks, Tractors, etc.
  • NOTE: One pint treats 8-25 gallons of gas (average one ounce per gallon) or 6-12 gallons of gas oil mix (average 2 ounces per gallon.) Does not replace oil. Use frequently.
