How much Sea Foam Fuel Injector Cleaner to add
The amount of Sea Foam Fuel Injector Cleaner you should add depends on the type of vehicle and its usage.
For cars and trucks that are driven regularly, it is recommended to add Sea Foam to your fuel every 3,000 miles. For maximum cleaning, you can add a full 16 oz can of Sea Foam to a low tank (2-3 gallons) and drive until almost empty before refuelling.
For small engines, such as those in riding lawn mowers, power washers, or trimmers, you can add Sea Foam whenever you refuel. For engine equipment used regularly, it is recommended to 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, you can add Sea Foam to every tank of fuel. It is safe to add more Sea Foam for a better cleaning effect.
Additionally, Sea Foam can be used in injector cleaning machines. For these machines, a 50/50 mix with gas is recommended. For diesel injector cleaning machines or when priming diesel fuel filters, you can use 100% Sea Foam.
Sea Foam is made from petroleum ingredients and is safe to use in all types of gasoline or diesel fuels and fuel blends. It will not harm any parts or components of your engine and can even help prevent fuel degradation in vehicles that are not frequently driven.

How often to use Sea Foam Fuel Injector Cleaner
Sea Foam IC5 Fuel Injector Cleaner is a fuel additive that helps clean fuel injectors and carburettors, removing harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas. It is designed to be used regularly to prevent engine issues such as hard starts, rough idling, and engine hesitations.
The frequency of use depends on the type of engine and how often it is used. For cars and trucks driven regularly, it is recommended to add Sea Foam to the fuel every 3,000 miles or every three months, whichever comes first. This can be done by adding a full bottle of Sea Foam IC5 Fuel Injector Cleaner to the fuel tank when it is low on fuel, and then filling up the tank with gasoline. One bottle treats up to 25 gallons or 95 litres of fuel.
For small engines, such as those in lawn mowers or power washers, Sea Foam can be added whenever you refuel. This will help to keep the fuel system clean and lubricated.
If you are using Sea Foam to clean a gasoline or diesel fuel system, it is safe to add more Sea Foam to the fuel for maximum cleaning. The more Sea Foam you add, the better it cleans. However, some mechanics recommend using a fuel injection cleaner with PEA for modern cars, as Sea Foam is designed for 2-stroke engines and may not be as effective for 4-stroke engines.

Which engines Sea Foam Fuel Injector Cleaner is suitable for
Sea Foam Fuel Injector Cleaner is suitable for a wide range of engines and fuel types. It is designed to clean and lubricate the entire fuel system, including fuel injectors and carburetors, removing harmful residues and deposits. The product is safe and effective for both gasoline and diesel fuel systems and can be used in cars, trucks, and small engines.
For gasoline engines, Sea Foam is a safe and effective option. It is made from petroleum ingredients and does not contain harsh detergents or abrasive chemicals, ensuring it won't harm engine or fuel system components. In fact, the more Sea Foam you add to the fuel, the better it cleans. This makes it a good choice for engines with significant build-up. It is also useful for removing water from gas tanks, which can be an issue during seasonal changes due to condensation.
For diesel engines, Sea Foam is equally effective. It can be used in diesel injector cleaning machines and when priming diesel fuel filters. Sea Foam Motor Treatment (SF16) is a suitable option for cleaning diesel injectors while also treating the entire fuel system. Additionally, Sea Foam High Mileage (HM16) is specifically designed for high-mileage diesel engines, helping to improve performance and extend vehicle life.
It's important to note that while Sea Foam is versatile, some modern cars with catalytic converters may not be the best candidates for this product. This is because Sea Foam is made of naphtha and pale oil, which may not be suitable for burning in modern engines with catalytic converters. In such cases, a fuel injection cleaner with PEA (polyether amine) is recommended.
Overall, Sea Foam Fuel Injector Cleaner is a versatile and effective solution for a wide range of engines, including gasoline, diesel, and small engines. It is a safe and powerful cleaner that can help maintain engine performance and prolong the life of vehicles.
