Sea Foam Motor Treatment is a fuel additive that can be used to clean and lubricate fuel systems. It is made from petroleum-based ingredients and is safe to use in all types of gasoline and diesel engines. The amount of Sea Foam to add to fuel depends on the desired level of cleaning and lubrication. For maximum cleaning, a higher ratio of Sea Foam to fuel is recommended, with a 1:2 ratio being the highest concentration. For fuel stabilization, a lower ratio of 1 ounce of Sea Foam per gallon of fuel is recommended. Sea Foam can also be used in injector cleaning machines, small engines, and for preventative maintenance, with varying ratios depending on the specific application.

Sea Foam cleans and lubricates fuel systems
Sea Foam is a petroleum-based product that can be used to clean and lubricate fuel systems. It is safe to use in all types of gasoline and diesel engines and does not contain harsh detergents or abrasive chemicals that can harm your engine.
To use Sea Foam for fuel system cleaning, it is recommended to add a higher concentration of the product to a low tank of fuel. The general rule is that the more Sea Foam you add to fuel, the better it cleans. For example, for a gasoline or diesel fuel system, you can add 2 or more ounces of Sea Foam per gallon of fuel. If you want to maximize cleaning, you can add a full 16-ounce can of Sea Foam to a low tank (2-3 gallons) and drive until the tank is almost empty before refueling.
For small engines, such as those in generators, you can add a full can of Sea Foam Motor Treatment when the fuel level is around half full and then run the engine until it is almost empty. This allows the Sea Foam to work through the system and clean any residues that may have formed during storage.
In addition to cleaning, Sea Foam also helps to stabilize stored fuel for up to two years. It prevents the formation of gum and varnish in the fuel system, which are common causes of poor engine performance. Sea Foam also adds protective lubricity to the fuel, which can be beneficial in engines that use ethanol or gasoline.

It's safe to add more Sea Foam to fuel for better cleaning
Sea Foam Motor Treatment is a safe and effective fuel additive that can be used in all types of gasoline or diesel engines. It is made from petroleum-based ingredients and does not contain harsh detergents or abrasive chemicals that can harm your engine or fuel system components.
When it comes to cleaning your fuel system, adding more Sea Foam to your fuel will enhance its effectiveness. The standard recommendation for cleaning is to add 2 or more ounces of Sea Foam per gallon of fuel, with the option of going up to a 1:2 ratio of Sea Foam to fuel for a more concentrated cleaning solution. This higher concentration is particularly useful for addressing stubborn residues and deposits, especially in older vehicles.
For maximum cleaning power, it is suggested to add a full 16-ounce can of Sea Foam to a low tank (2-3 gallons) and then drive until the tank is almost empty before refuelling. This method ensures that the Sea Foam has sufficient time to circulate and clean the entire fuel system, including fuel injectors and carburetors.
Sea Foam is an excellent choice for those seeking to improve the performance and longevity of their engines. By adding a higher concentration of Sea Foam to fuel, you can be confident in its ability to thoroughly clean and protect your engine, ensuring optimal performance and a smoother driving experience.

Sea Foam stabilizes fuel for up to two years
Sea Foam is a petroleum-based product that is safe to use in all types of gasoline and diesel engines. It does not contain harsh detergents or abrasive chemicals that can harm your engine or fuel system components. It is designed to clean and lubricate your entire fuel system, working through fuel injectors and carburetors to remove harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas.
Sea Foam can be used to clean and stabilize fuel. For cleaning, it is recommended to add a higher concentration of Sea Foam to a low tank of fuel, with a ratio of up to 1:2 Sea Foam to fuel. This will increase the cleaning concentration and allow the Sea Foam to circulate and clean more effectively. It is also safe to add more Sea Foam to fuel for cleaning, as the more you add, the better it cleans.
For stabilizing fuel, Sea Foam can be added to stored tanks to help fuel resist evaporation, preserve ignition vapors, add protective lubricity, and prevent the formation of gum and varnish in fuel systems. Gum and varnish residues are the most common cause of poor engine function, and Sea Foam works to clean and prevent these residues from forming. To stabilize fuel, it is recommended to add 1 ounce of Sea Foam per gallon of fuel. Sea Foam will help your engines start easier and last longer, and it can stabilize stored fuel for up to two years.
It is important to note that Sea Foam should not be relied upon to completely counter the harmful effects of ethanol in fuel, particularly when left in a tank for a long period of time. However, it can help protect against ethanol and water, and it is safe to use in engines that are built to handle ethanol. For small engines, it is recommended to use non-ethanol fuel and avoid letting the fuel sit in the tank for long periods.
