Seafoam is a fuel additive that can be added to a fuel tank to clean and lubricate the fuel system. It is made from petroleum ingredients and is safe to use in all types of gasoline or diesel fuels and fuel blends. Some people add it to their fuel tanks to improve engine performance and prolong engine life, while others use it to pass emissions testing. It is recommended to add 1 ounce of Sea Foam per gallon of fuel for regular fuel system maintenance and 2 or more ounces per gallon for cleaning. However, there are mixed opinions on whether adding Sea Foam to a fuel tank is beneficial or necessary, as modern fuel seems to be effective on its own.
| Characteristics | Values |
|---|---|
| Purpose | Cleaning and lubricating fuel systems, including fuel injectors and carburetors |
| Usage | Add 1 oz of Sea Foam per gallon of fuel for maintenance. For cleaning, add 2 oz or more per gallon to a low tank. For small engines, add whenever refueling. For engine equipment used regularly, add to a fresh tank fill every 3 months or sooner. |
| Benefits | Helps engine run better and last longer, improves performance, stabilizes fuel, and helps pass emissions testing |
| Precautions | Some users report mixed results and potential for negative long-term effects. Modern fuel may already provide adequate cleaning without additives. |

Sea Foam can be added to a low fuel tank for a more concentrated mixture
Sea Foam can be added to a fuel tank to clean and lubricate the fuel system. It works by removing harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas. Sea Foam is particularly effective at cleaning fuel injectors and carburetors.
For those looking to clean their fuel system, Sea Foam can be added to a low fuel tank for a more concentrated mixture. It is recommended to add one 16-ounce can of Sea Foam to a low tank (1/4-1/8 full) and then drive for at least 20-50 miles before refueling. This allows the stronger Sea Foam mixture to run through the system and provide a more thorough cleaning.
The ratio of Sea Foam to fuel can be adjusted for a more concentrated mixture. For regular fuel system maintenance, one ounce of Sea Foam per gallon of fuel is sufficient. However, for a more concentrated cleaning mixture, two or more ounces of Sea Foam per gallon of fuel can be added. It is important to note that Sea Foam will not fix a broken fuel pump, but it can help with carbon build-up in the engine when used correctly.
Sea Foam Motor Treatment can also be used to stabilize stored fuel for up to two years. Adding Sea Foam to stored fuel helps prevent evaporation, preserves ignition vapors, adds lubrication, and stops the formation of gum and varnish residues, which are common causes of poor engine function.

It is safe to add Sea Foam to gasoline or diesel fuel systems
Sea Foam can be safely added to gasoline or diesel fuel systems. It is made from petroleum ingredients and is safe and effective when used in all types of gasoline or diesel fuels and fuel blends. The more Sea Foam you add to fuel, the better it cleans.
For regular fuel system maintenance, add 1 ounce of Sea Foam per gallon of fuel. For cleaning, add 2 or more ounces per gallon to a low tank. For injector cleaning machines, use a 50/50 mix of Sea Foam and gas. For 2-stroke pre-mix, add 2 ounces of Sea Foam per gallon of fuel. For stabilizing fuel, add 1 ounce of Sea Foam per gallon of fuel.
Sea Foam can be added directly to the fuel tank and allowed to run through the system by normal driving. It works through fuel injectors and carburetors to remove harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas. It can also be used to clean diesel injector cleaning machines and when priming diesel fuel filters.
Some people have reported that adding Sea Foam to their fuel tank has helped them pass emissions testing and improved engine performance. However, others have not noticed any difference in their vehicles after using Sea Foam, and some believe that modern fuel does not require additional additives. It is always a good idea to follow the directions on the Sea Foam packaging and check with the vehicle manufacturer before adding any additives to fuel.

Sea Foam is useful for cleaning fuel injectors and carburetors
Sea Foam is a fuel and oil additive that can be used to clean fuel injectors and carburetors. It is safe to use in both gasoline and diesel engines and can be added directly to the fuel tank. The amount of Sea Foam to be added depends on the level of cleaning required and the size of the fuel tank.
For maximum cleaning, it is recommended to add a full 16 oz can of Sea Foam to a low tank (2-3 gallons) and drive until almost empty before refuelling. For regular fuel system maintenance or to prevent gum and varnish build-up, a smaller amount of Sea Foam can be added to the fuel tank—typically, 1 ounce of Sea Foam per gallon of fuel is recommended. This can be done more frequently, such as every 3,000 miles for regularly driven cars and trucks.
Sea Foam works by removing harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas. It is made from petroleum ingredients and does not contain harsh detergents or abrasive chemicals that could harm the engine or fuel system components. It is a safe and effective way to clean fuel injectors and carburetors, helping to improve engine performance and fuel efficiency while reducing emissions.
Some users have reported successful experiences using Sea Foam to clean their fuel injectors and improve engine performance. However, it is important to follow the directions on the can and use the appropriate amount of Sea Foam for the specific engine and fuel system.

Sea Foam can be used to stabilize stored fuel for up to 2 years
Sea Foam is a fuel additive that can be used to clean and lubricate fuel systems. It is made from petroleum ingredients and is safe to use in all types of gasoline, diesel fuels, and fuel blends. While some people have expressed doubts about its effectiveness, others swear by it, particularly for use in outboard motors and fishing forums.
Sea Foam can be added directly to the fuel tank and then driven as normal. For maximum cleaning, it is recommended to add a full 16 oz can of Sea Foam to a low tank (2-3 gallons) and drive until almost empty before refuelling. However, it is important to note that the more Sea Foam you add to fuel, the better it cleans. For regular fuel system maintenance, add 1 ounce per gallon. For cleaning, add 2 or more ounces per gallon to a low tank. For small engines, add Sea Foam whenever you refuel. For engine equipment used regularly, add Sea Foam to a fresh tank fill every 3 months or sooner.
Sea Foam can also be used to stabilize stored fuel for up to 2 years. To do this, add at least 10mL of Sea Foam for each liter of tank fuel. Run the engine long enough for the treatment to work through the entire fuel system. When possible, adding more Sea Foam when the tank is low will increase the cleaning and lubricating ratio when working the treatment into the engine.
Sea Foam is a safe and effective way to clean and maintain fuel systems, and it can also be used to stabilize stored fuel for extended periods.

Sea Foam may help with carbon build-up in the engine
Sea Foam can be added to the fuel tank to help with carbon build-up in the engine. It is made from petroleum ingredients and is safe and effective when used in all types of gasoline or diesel fuels and fuel blends.
Carbon build-up in the engine, or "engine carbon", is ash that occurs when fuel and oil molecules don't completely burn in the combustion chamber. This ash sticks to fuel gum or varnish that can form on intake valves, fuel injector nozzles, chamber hemispheres, and piston tops.
Sea Foam Motor Treatment can help to minimize carbon build-up in the engine. For a more aggressive approach to upper engine carbon, Sea Foam Spray can be used through the intake to clean intake valves and chamber areas. It is important to note that Sea Foam Spray does not pass through the fuel injectors.
To use Sea Foam for carbon build-up, it is recommended to run the gas tank low, add a full 16 oz can of Sea Foam, and then fill up the tank. The vehicle can then be driven until the tank is almost empty before refuelling. For regular fuel system maintenance, add 1 ounce of Sea Foam per gallon of fuel. For cleaning, add 2 or more ounces per gallon to a low tank.
Some people have reported success with using Sea Foam to clean carbon deposits around the throttle plate. However, others have noted that it may not be necessary for modern engines and that good fuel and regular oil changes are sufficient to prevent carbon build-up.
