Sea Foam is a fuel and oil additive that can be used in diesel engines to clean and lubricate the fuel system. It is designed to be poured directly into the fuel tank, where it works through fuel injectors and carburetors to remove harmful residues and deposits. The product is made from petroleum ingredients and is safe to use in all types of diesel fuels and blends. When using Sea Foam in a diesel engine, it is recommended to add 2 or more ounces per gallon of fuel for cleaning, with more product resulting in better cleaning power. It can also be used in diesel injector cleaning machines or when priming diesel fuel filters. Sea Foam is a popular choice for diesel engine maintenance, but it is important to note that it may not always add lubricity to diesel fuel and should be used with caution in cold weather to prevent gelling.
| Characteristics | Values |
|---|---|
| How to use | Pour Sea Foam into your fuel tank |
| How much to use | 2 or more ounces per gallon for cleaning; 15mL or more per liter for cleaning; 1 ounce per gallon for stabilizing fuel; 10mL per liter of fuel for stabilizing fuel for storage |

What You'll Learn
How much Sea Foam to add to diesel fuel for cleaning
Sea Foam can be used in diesel engines to clean and lubricate the 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 safe to add more Sea Foam to diesel fuel for cleaning, and the more you add, the better it cleans.
For cleaning, it is recommended to add 2 or more ounces of Sea Foam per gallon of diesel fuel. For maximum cleaning, you can add a full 16-ounce can of Sea Foam to a low tank (2-3 gallons) and drive until almost empty before refueling.
When using Sea Foam in diesel injector cleaning machines or when priming diesel fuel filters, it is recommended to use 100% Sea Foam. For 2-stroke pre-mix, add 2 ounces of Sea Foam per gallon.
It is important to note that Sea Foam is not designed to be used as a DPF (diesel particulate filter) cleaner. While it can help keep the DPF clean when used regularly, a specialized DPF cleaner should be used for cleaning a partially blocked DPF filter.

How often to add Sea Foam to diesel fuel
Sea Foam is a fuel and oil additive that can be used in diesel engines to clean injectors and add upper engine lubricity. It is made from petroleum ingredients and is safe and effective when used in all types of diesel fuels and blends. It does not contain harsh detergents or abrasive chemicals that can harm your engine or fuel system components.
When it comes to how often you should add Sea Foam to diesel fuel, the frequency depends on the type of engine and how regularly it is used. Here are some general guidelines:
- For cars and trucks driven regularly: Add Sea Foam to the fuel every 3,000 miles or 5,000 kilometres.
- For small engines: Add Sea Foam whenever you refuel.
- For engine equipment used regularly: Add Sea Foam to a fresh tank fill every three months or sooner.
- For all other engines and fuel tanks that are not used regularly: Add Sea Foam to every tank of fuel.
It is important to note that Sea Foam is not a substitute for proper maintenance and care of your diesel engine. Be sure to follow the recommended maintenance schedule for your specific vehicle or equipment and consult a qualified mechanic or technician if you have any questions or concerns.
Additionally, while Sea Foam can help protect against water and ethanol in the fuel, it is not a cure-all. It is important to take other precautions to prevent and manage these issues, especially if the fuel will be left in the tank for a long period.

Using Sea Foam in diesel fuel injector cleaning machines
Sea Foam is a popular fuel and oil additive that has been used since 1942 to help engines run better and last longer. It is safe and effective for use in all types of gasoline or diesel engines and fuel blends. It works by removing harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas.
To use Sea Foam in a diesel fuel injector cleaning machine, the product should be used at a concentration of 100%. This means that for every part of diesel fuel, an equal part of Sea Foam should be added. This mixture can then be run through the diesel fuel injector cleaning machine to effectively clean the injectors.
It is important to note that Sea Foam is not a substitute for regular maintenance and should be used in conjunction with other recommended cleaning and maintenance practices. Additionally, while Sea Foam can help protect against ethanol and water, it is not a guarantee against the harmful effects of ethanol in the fuel tank.
Sea Foam is also safe to use in diesel fuel tanks to clean injectors and add upper engine lubricity. It can be added directly to the fuel tank at a concentration of 2 ounces per gallon of fuel. The vehicle can then be driven as normal, and the Sea Foam will work to clean the injectors and improve engine performance.
For best results, Sea Foam should be used regularly and added to every fuel tank fill-up. This will help maintain clean engine performance and prevent common issues such as hard starts, rough idling, and engine hesitations.

Using Sea Foam to prime diesel fuel filters
Sea Foam is a fuel and oil additive that can be used to prime diesel fuel filters. It is made from 100% safe petroleum cleaning and lubricating ingredients and is compatible with all types of gasoline or diesel fuels and fuel blends.
To use Sea Foam to prime a diesel fuel filter, start by adding a cleaning dosage of Sea Foam to your fuel tank. It is recommended to add at least 2 ounces of Sea Foam per gallon of fuel when the tank is low to maximize the treatment concentration. For a stronger clean, add a full 16 oz can of Sea Foam to a low tank (2-4 gallons) and drive for at least 10-20 miles before refueling.
Next, start the engine and warm it up to operating temperature, then shut it off. Remove the primary fuel filter and drain the filter/filter housing. You can then choose to install a new filter. Depending on the filter type, fill the entire filter/housing cavity with straight Sea Foam.
Finally, install the new filter, ensuring there is no air in the filter or housing. With the filter primed, start the engine and let it run for one to two minutes, then shut off the engine.

How Sea Foam works in diesel fuel
Sea Foam is a fuel and oil additive that can be used in diesel engines to clean and lubricate the fuel system. It is safe and effective to use in all types of diesel fuels and blends, and it does not contain any harsh detergents or abrasive chemicals that could harm your engine.
To use Sea Foam in a diesel engine, simply pour it into your fuel tank. The amount you pour will depend on your desired level of cleaning. For regular cleaning, use 2 or more ounces of Sea Foam per gallon of fuel. For maximum cleaning, add a full 16-ounce can of Sea Foam to a low tank (2-3 gallons) and drive until almost empty before refuelling.
Sea Foam works by removing harmful residues and deposits from fuel injectors, carburetors, fuel passageways, intake valves, pistons, and chamber areas. It can also be used to clean diesel injector cleaning machines and prime diesel fuel filters.
In addition to its cleaning properties, Sea Foam also adds protective lubricity to fuel and fuel system parts. This helps to protect against ethanol and water, although it should not be relied upon completely to counter the harmful effects of ethanol. Sea Foam can also help prevent diesel fuel from turning to gel in cold weather, although specialized anti-gel treatments may be more effective in extremely cold temperatures.
