Sea Foam Motor Treatment can be used in any gas engine
Sea Foam Motor Treatment is a fuel and oil additive that can be used in any gas engine. It is safe and effective for all types of gasoline or diesel fuels and fuel blends. It is made from petroleum ingredients and does not contain harsh detergents or abrasive chemicals that could harm your engine or fuel system.
Sea Foam can be added directly to the fuel tank to clean and lubricate the entire fuel system. It works through fuel injectors and carburetors to remove harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas. It is also safe to use in fuel injectors and carburetors.
Sea Foam is a slow-acting formula that gradually re-liquefies gum, sludge, varnish, and carbon deposits, allowing them to be flushed out of the system. It also helps to lubricate moving parts, especially in the fuel system, and absorbs water inside the fuel tank, allowing it to be burned in the combustion chamber without issue.
Sea Foam Motor Treatment can be used in various gasoline-powered machines, including lawn mowers, power washers, and trimmers. It is also suitable for marine engines, helping to prevent and overcome common marine engine problems caused by fuel residues, such as rough idling, hard starting, and loss of power. For seasonal storage, Sea Foam can be added to stored fuel to resist evaporation, preserve ignition vapors, and prevent the formation of gum and varnish, keeping engines starting easily and lasting longer.

Sea Foam is safe and effective when used in all types of gasoline
Sea Foam is a fuel and oil additive that has been trusted by mechanics and engine owners for over 70 years. It is safe and effective when used in all types of gasoline or diesel fuels and fuel blends. Sea Foam does not contain harsh detergent or abrasive chemicals that can harm your engine or fuel system components. Instead, it is made with petroleum ingredients that slowly re-liquify the gum, sludge, varnish and carbon deposits in your engine so they can be flushed out.
Sea Foam is particularly useful in gasoline direct injection engines, where it works through fuel injectors and carburetors to remove harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas. It also helps lubricate the moving parts, especially in the fuel system. This is important because ethanol additives dry out the seals, making it harder for oil to lubricate the parts.
Sea Foam can be used in any gas or diesel engine, including riding lawn mowers, gas power washers, and gas trimmers. It can also be used to store engines, helping to stabilize fuel for up to two years. When used in stored fuel, Sea Foam helps fuel resist evaporation, preserves ignition vapors, adds protective lubricity, and prevents the formation of gum and varnish in fuel systems.
To use Sea Foam for fuel system cleaning or to overcome a fuel-related engine problem, it is recommended to add 2 or more ounces of Sea Foam per gallon of fuel. To maximize cleaning, add a full can (16 oz) to a low tank (2-3 gallons) and drive until almost empty before refueling. This can be done every 3,000-5,000 miles to keep your fuel system and critical engine areas clean.

Sea Foam Motor Treatment stabilises stored fuel for up to 2 years
Sea Foam Motor Treatment is a fuel and oil additive that can be used in any gas or diesel engine. It is safe and effective when used in all types of gasoline, diesel fuels, and fuel blends. Sea Foam does not contain harsh detergent or abrasive chemicals that can harm your engine or fuel system components. It is made with a blend of petroleum cleaning and lubricating ingredients.
Sea Foam Motor Treatment works to stabilize stored fuel for up to 2 years. Adding Sea Foam to stored tanks helps fuel resist evaporation, preserves ignition vapors, adds protective lubricity, and prevents the formation of gum and varnish in fuel systems. Gum and varnish residues are the most common cause of poor engine function. By preventing the formation of these residues, Sea Foam helps your engines start easier and last longer.
To use Sea Foam Motor Treatment for fuel stabilization, it is recommended to add a high concentration of the product to your fuel tank once a year. This involves waiting until your fuel tank is low and adding a 2:1 ratio of gas to Sea Foam (for example, 32 oz of fuel and 16 oz of Sea Foam). Then, you can ride it until it is almost empty before refueling. This high concentration will effectively clean any fuel residue or deposits.
Additionally, if your vehicle will be sitting for a while between uses, you can add 1 oz of Sea Foam per gallon of fuel to every tank. This will help maintain the fuel's stability and prevent the formation of gum and varnish during storage. Sea Foam Motor Treatment is an effective way to keep your fuel fresh and your engine in top working condition.
