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.

                Seafoam will clean out your whole fuel system, stops rough idle, will defiantly improve gas mileage and power. If u want it to clean more put it through your vacuum line that goes to the intake manifold leave it for 5 minutes and watch it burn off all the gunk in it through all the smoke.

                      I added 1 bottle of sea foam to my car and the car still will not start, is it safe to add another bottle of sea foam to the same gas that has the previous sea foam in it or can you recommend some other way of getting the car started , I was told that there might be to much gunk in the gas tank and that sea foam would clear it out?

                      Can I or really I should ask, should I use Seafoam at every fill up or is that to much? And lets say the answer is yes, I could use it every fill up, can I also use it in the oil and vacuum line or should I only wait till I'm about to get an oil change to put it in the oil and vacuum?

                        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.

                        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.

                        Hi Ben, happy to help! Locate the fuel filler port on your vehicle and fill the tank to capacity with 91 or higher octane gasoline prior to adding the Seafoam. Remove the cap on the fuel filler port. Insert a funnel through the port. Shake the can of Seafoam well and pour the entire can into the gas tank. Start and drive the vehicle for a short distance. The Seafoam will mix with the gasoline, cleaning both the gas tank and the vehicle's fuel system. A large amount of smoke may come out of the tailpipe, but this is normal. Use the entire tank before adding more gasoline in order to avoid diluting the Seafoam cleaning solution.
