Frequency of adding Sea Foam
The frequency with which you should add Sea Foam to your fuel tank depends on several factors, including the type of vehicle, engine usage, and the purpose of adding Sea Foam (for maintenance or cleaning). Here is a detailed breakdown of how often to add Sea Foam to your fuel tank:
Cars and Trucks Driven Regularly
For regularly driven cars and trucks, it is recommended to add Sea Foam to the fuel tank every 3,000 miles or 5,000 kilometers. This frequency ensures that your fuel system is maintained and kept clean.
Small Engines
Small engines, such as those in motorcycles, should have Sea Foam added to the fuel tank more frequently. It is recommended to add Sea Foam whenever you refuel these smaller engines.
Engine Equipment Used Regularly
For engine equipment that is used regularly, such as lawn mowers or tractors, it is advised to add Sea Foam to a fresh tank of fuel every three months or sooner. This helps maintain the equipment and prevent fuel-related issues.
Infrequently Used Engines and Fuel Tanks
For engines and fuel tanks that are not used regularly, it is recommended to add Sea Foam to every tank of fuel. This practice helps preserve the fuel and prevent issues that may arise from fuel degradation.
Cleaning Gasoline or Diesel Fuel Systems
When using Sea Foam to clean a gasoline or diesel fuel system, you can add a higher concentration of Sea Foam for a more effective clean. It is recommended to do this once a year. Wait until your fuel tank is low (approximately 1/4 to 1/8 full) and add a full 16-ounce can of Sea Foam. Then, drive at least 10-20 miles before refueling. This process can be repeated every 3,000 to 5,000 miles to maintain a clean fuel system.
Storing Vehicles or Fuel Tanks
If you are storing a vehicle or fuel tank for an extended period, it is recommended to add 1 ounce of Sea Foam per gallon of fuel. This helps prevent gum and varnish buildup, preserve ignition vapors, and maintain fuel stability during storage.

Sea Foam for injector cleaning machines
Sea Foam is a fuel and oil additive that can be used to clean and lubricate your entire fuel system. It is safe and effective to use in any gas engine and can be poured directly into your fuel tank.
For injector cleaning machines, Sea Foam can be used in different ways depending on the type of machine and fuel. For injector cleaning machines using gasoline, it is recommended to use a 50/50 mix of Sea Foam and gas. This means using a 2:1 ratio of gas to Sea Foam, or 32 ounces of fuel and 16 ounces of Sea Foam. This high concentration of Sea Foam will effectively clean any fuel residue or deposits in the injector.
For diesel injector cleaning machines, it is recommended to use 100% Sea Foam. This is because diesel fuel injectors may require a stronger cleaning solution. By using undiluted Sea Foam, you can ensure that the injectors are thoroughly cleaned.
In addition to cleaning injectors, Sea Foam can also be used to stabilize fuel and clean gum and varnish from the fuel system. For fuel stabilization, add 1 ounce of Sea Foam per gallon of fuel. This will help preserve ignition vapors and prevent the fuel from degrading, especially during storage.
It is recommended to use Sea Foam for regular fuel system maintenance and cleaning. For maintenance, add 1 ounce of Sea Foam per gallon of fuel. For a deeper clean, wait until your fuel tank is low (around 1/4 to 1/8 full) and add a full 16-ounce can of Sea Foam. Then, drive until the tank is almost empty before refueling. This process can be repeated every 3,000 to 5,000 miles to keep your fuel system clean.

Sea Foam for diesel injector cleaning machines
Sea Foam is a leading fuel and oil additive manufacturer that has been trusted for over 80 years. Its products are designed to help engines and equipment run better and last longer.
Sea Foam can be used to clean fuel injectors in diesel engines. This can be accomplished by getting the engine to operating temperature and then shutting it off. The next steps involve removing the fuel filter and emptying all diesel fuel from the filter or filter housing. The filter or housing is then filled with straight Sea Foam. The filter is reinstalled, and the engine is started and allowed to run for about two minutes before being shut off and left to sit for approximately five minutes. This process is called a "HOT SOAK", allowing the Sea Foam to soak into the carbon deposits.
After the "hot soak" period, the engine is restarted and road-tested by driving aggressively for about 5 miles. This process cleans carbon deposits from the injectors and the combustion chamber inside the engine. Sea Foam can also be used in oil for cleaning the crankcase.
For injector cleaning machines, it is recommended to use a 50/50 mix of Sea Foam with gas. However, for diesel injector cleaning machines, 100% Sea Foam should be used. This higher concentration ensures effective cleaning of the diesel injectors.
Sea Foam is safe to use and provides various benefits for diesel engines. It adds lubricity to the fuel, protecting moving parts from excessive friction damage. It also controls moisture, degels frozen diesel fuel, and cleans fuel residues from the entire fuel system. Additionally, Sea Foam helps clean the fuel pump and lubricates the O-rings, ensuring the smooth operation of the engine.
