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.

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.

        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.

Can this product be used in this case and will help with a situation of the trimmer is not running well I think because there was some older gas in the unit that may have gummed up the carb as it was running well when used 5 months ago.

                  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.
