Seafoam engine treatment.

You will be amazed what this product can do. It typically is used as a fuel system additive, but has many other uses. When used as a fuel system additive you should expect almost immediate results. The primary ingredient burns very rapidly and at an extremely high temperature producing a burn-off cleaning effect within the engine and exhaust system. This may cause your engine to run much smoother and quieter. It can also be used as a engine flush to aid in the removal of built up gunk and sludge.

The product is also available in one gallon cans.

Warning: Burns extremely hot!
Use caution when the application is air-cooled.

Sea Foam

Use Shell/BP in my car so I haven't noticed any difference in 5000 mi. maybe if I used lower quality gas it would make a difference.

    Comments about Sea Foam Motor Treatment for Gas and Diesel Engines (16 fl. oz.):

    Gave my 98 GMC Sierra 4x4 the Sea Foam treatment. It cleaned carbon deposits and improved injector and engine performance. Ran about 6 oz. through the intake manifold and saw an improvement in engine performance. You could actually see the carbon being blown out of the exhaust pipes. Gas mileage and overall engine power improved. I'm going to do the treatment on my 06 Trailblazer.

      Comments about Sea Foam Motor Treatment for Gas and Diesel Engines (16 fl. oz.):

      I recently purchased a used 2008 Honda Shadow Aero 750 with 5,500 original miles. The bike did not get rode frequently enough and sat for approx 10 months. It did not run very well so I drained the old gas and filled it back up with fresh high octane gas (3 gallons) and 8 0zs of SeaFoam. This stuff really helped. After letting the bike idle for about 45 mins and riding for around 80 miles the carburetor functioned much better. The hesitation and back firing stopped. I ran SeaFoam through the fuel system for two more gas tanks full and the bike got even better. GREAT STUFF! I'll be using it in my other two bikes also.

            I am typically not a believer in 'snake oils' or mechanic-in-a-can chemicals, HOWEVER, I am a true believer in Sea Foam.

            I've cured rough idling small engines with it. I've cured hard to start symptoms. I've cured bogging engines with it. I've also used it as a fuel stabilizer.

            I run a can through my lawn mower every spring as well as mix a can with a gallon of 2 cycle mix for my trimmer and chain saw. I use it in my 175HP outboard boat engine the 1st trip out every spring. I truly believe it aides in keeping all my gas burning engines running top notch and trouble free.

              This works great for removing build up in Ford/Lincoln products. I didn't see so much with my GM products.
              I read about using the brake booster vacuum hose to pull it into the engine. Talk about some smoke. The Lincoln blew junk out for a while.

                    A:

                    Hi Hal, good question! It depends on what fuel you are treating. The premixed two cycle fuel of one can will treat 8 gallons of fuel. In any straight gas in cars, trucks or 4 cycle engines, 16 ounces of Sea Foam treats 16 gallons of fuel (ave. 1 ounce per gallon). Also, 16 ounces of Sea Foam will treat 25 gallons of diesel fuel.

                    Hi Xavi, glad to help you! Sea Foam is a safe and versatile additive that can be used in fuel, oil or added directly into the combustion chamber on 2-cycle, 4-cycle, rotary engines and can be used in diesel engine fuel and oil systems only. Sea Foam is a petroleum blended product, so it is as safe for seals, o-rings, sensors and other fuel system and engine components as the fuel or motor oil that runs the engine. Sea Foam contains NO harsh chemical detergents.
