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.

    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.

                    I have a gas hedge trimmer that runs on a gas/oil mix. 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.

                      A:

                      Great question, Chris! Sea Foam is a great product for cleaning up your engine. I wouldn't say that you need to use it at every fill up. I do recommend that you put quality gasoline in your vehicle to avoid any build-up in your intake and cylinders. Sea Foam will help clean your engine's crankcase, upper cylinders and intake, as well as the fuel lines. For use in your oil and vacuum line I would definitely wait until you are ready for an oil change before adding to the crankcase or vacuum line. After you've used the product to clean up your engine I recommend continuing to use high quality motor oil and gasoline and you should not need to continue to treat the engine with anything to clean the engine. Many fuels now have active cleaning ingredients as well as many of the high quality motor oils. Also make sure that your vehicle manufacturer does not prohibit the use of additives to avoid problems with your warranty.

                      A:

                      Hi Dave, great question! This Sea Foam Motor Treatment for Gas and Diesel Engines is great for tuning up diesel engines and small engines. When added to diesel fuel tank, cleans fuel injectors, de-ices and removes moisture, cleans carbon as you drive, diesel fuel conditioner and anti-gel, lubricates upper cylinders, stabilizes fuel, adds lubricity. One pint treats 25 gallons of fuel. When used for Small Engine Applications, works and performs instantly to stabilize fuel, clean carburetor, clean carbon, remove moisture, assure fast starts, free sticky rings, restore power, lubricate upper cylinder and smooth rough idle. This is a fuel stabilizer for up to 2 years. Always run the engine for a long enough period of time to assure the Sea Foam Motor treatment has been drawn through the entire system fuel system for complete protection. Add 1 oz. Sea Foam® Motor Treatment per gallon of fuel. You can mix up to 2 oz. per gallon of fuel if necessary. Mixing at less than two-thirds oz. per gallon will impair the effectiveness of Sea Foam.
