Benefits of adding seafoam in oil


  • Crankcase health


By adding seafoam in oil, you can ensure that your crankcase runs cleaner, does not have any extra contaminants inside of the mechanism, and it lasts longer for a more durable and long-lasting part in your vehicle. 


A crankcase is the housing for the crankshaft in the internal combustion engine of a vehicle. In most engines in modern cars today, the crankcase is usually integrated within the engine block. Including seafoam in oil can help this important part of your vehicle last even longer! 


Two-stroke engines usually utilize a crankcase-compression design, causing the fuel and air mixture to pass through the resulting crankcase before entering the engine cylinders. This particular engine design means that there is no oil sump within the crankcase or the crankcase pressure sensor.


The crankcase usually forms the lower half of the main bearing journals in a vehicle, with the bearing caps completing the other half. Within the crankcase, you have the crankcase pressure sensor. The main bearing journals that hold the crankcase are the bearings that hold the crankshaft in place and rotate within the engine. 


Adding seafoam in oil can help your crankcase last even longer and prevent any necessary crankcase repair or replacements.

  • Engine Lubrication


Adding seafoam in oil can help liquefy any petroleum residue lingering in your fuel system and provides more engine lubrication to increase your vehicle’s oil flow. 


Adding seafoam in oil can help you keep your engine running longer – you can understand how this works by knowing the importance of engine oil in your car. The type of engine oil you need varies depending on the engine’s performance engine and when the engine was manufactured. 


Newer engines have more specific fuel economy requirements for oil consumption, with older engines having a wider variety of oil types that can be used. If you realize any low engine oil symptoms, then you will have to refill the tank. 


Preventing low engine oil symptoms can prevent your engine from running erratically and causing a drop in performance. In addition, low engine oil can lead to a problem with the engine, leading to expensive and severe issues. By recognizing and fixing low engine oil symptoms, you can keep your car running at an optimal performance level. Keep reading to find out the symptoms of low oil so you can fix this problem by adding seafoam in oil!

Importance of Engine Oil

  • Engine oil needs to provide proper lubrication for the internal engine parts that are susceptible to overheating, excess friction, and rubbing against each other during use. The lubrication aids in keeping the moving parts protected and preventing them from excess wear and tear. Without the engine oil and seafoam in oil, metal-on-metal contact would damage your engine to the point of no return very shortly, leading to an expensive and extensive replacement. 
  • The second main reason why engine oil is vital for your vehicle is cooling the parts due to overheating. Most of the cooling required is supplied by the coolant system, like the radiator or the water pump. Preventing overheating can occur by adding more seafoam in oil in your vehicle. 
  • The last reason why engine oil is essential in your car is to clean the engine and prevent any buildup of debris, dirt, and contaminants. The seafoam in oil can act as a cleaner to your fuel and engine system, removing any unwanted dirt inside of this important distribution system. 



  • Cleaning the Engine Mechanism


Another benefit of using seafoam in oil is to clean oil control rings and actuators. The engine control unit’s parts, the actuators, and the internal combustion engine are crucial to the powertrain control module’s functioning. The actuators are components of a machine that are responsible for the moving of the mechanics within the system. 


The internal combustion engine uses fuel combustion within a combustion chamber to aid in the fluid flow circuit. The expansion of high-temperature and high-pressure gasses fuel the vehicle and aid in the working powertrain control module. 


  • Cleaning the Crankcase


An additional positive of adding seafoam in oil to your engine can help dissolve and clean harmful and contaminated deposits through the crankcase, including any soot residue that has built up over time. 


  • Fixing noisy lifters


The last benefit of using seafoam in oil is to quiet noisy lifters inside of your vehicle. The hydraulic valve lifter, also known as just the lifter, is a small cylinder positioned adjacent to the hydraulic valve. The lifter and the valve work together and are connected by a small rod, known as the rocker arm.


The lifter in your vehicle is in charge of ensuring that the engine works quietly and performs at the adequate performance level for you and your vehicle. 

Rocker Arm Function

A rocker arm refers to a part in your vehicle’s internal combustion engine, helping it run efficiently and safely. This moving lever transfers the radial movement from the cam lobe into a linear movement that can be used to power the car. The cam lobe is a rotating piece in the linkage chain that transfers rotary into linear motion, delivering power to propel the engine.


As you will find in this article, a rocker arm plays an important role in your engine’s main function, helping keep the pressure at the correct level and aiding in the ignition timing to prevent engine misfiring and overheating. Adding seafoam in oil can ensure that the rocker arm moves at the correct speed and angle to keep your engine working correctly.


As you will find in this article, a rocker arm plays an important role in your engine’s main function, helping keep the pressure at the correct level and aiding in the ignition timing to prevent engine misfiring and overheating. Adding seafoam in oil can aid in the protection against misfiring and overheating. 


The other end of the rocker arm that is not being moved up and down acts as the valve stem, which opens to let gas into the chamber and then closes to keep the gas in the chamber, altering the chamber’s pressure to keep it at the right level. The valve stem keeps the right air and fuel mixture within the engine, allowing for proper timing of ignition and combustion.

Using Seafoam in Oil


  • Using Seafoam in the Crankcase


One of the main ways that you can add seafoam in oil is to use this product in the crankcase to take care of any unwanted engine oil sludge. Adding seafoam in oil can help clean deposits out of your crankcase and oil system to ensure proper liquid movement and prevent overheating. 


In many cars, including modern and older cars, sludge can build up over time in the crankcase and impede and block where the oil is supposed to flow. If the oil cannot travel properly or quickly enough, the oil will build up and lead to dirt and debris contamination. 


Seafoam in oil can help move, dissolve, and dislodge the buildups so they can be filtered out and removed before they cause any extra damage. The best way to use seafoam in oil for your crankcase health is to use 1.5 ounces of seafoam for every quart of engine oil. 


If you have decided to use seafoam in your engine’s oil, you have to change your oil before moving on any further steps quickly. Add seafoam to the oil just before you go for an oil change so that the seafoam has a chance to soak in while you are diving to the nearby local mechanic or auto body store. This gives the seafoam in oil a chance to break down any unwanted sludge in your car. 


Lastly, make sure that you change your oil filter when you add the seafoam in oil. The seafoam will turn the old built-up sludge back into a liquid and cause your oil to become even dirtier, so you can’t drive too far without cleaning the oil filter of the built-up debris and sludge. 


  • Using Seafoam in Gas Tank


Seafoam in oil can also be used for your gas tank health and longevity. Using seafoam in oil will help clean the fuel injectors and increase your fuel economy to prevent any unwanted drop in engine performance. Providing a better idle and preventing rough engine idle can help you ensure your fuel system’s lifespan.


All you have to do is pour in the necessary amount of seafoam in oil and drive as you normally would. The seafoam in oil in the gas tank will help clean out any extra deposits as you drive your car and will slowly begin to increase your fuel economy by cleaning out the fuel injectors and fuel lines. 


In addition to using seafoam in oil in your gas tank, the seafoam can help eliminate this extra liquid if there is water in your gas tank. If you use seafoam for this sole purpose of wanting to remove water from your gas tank, then you should use one ounce of seafoam per gallon of gas.


  • Using Seafoam in the Intake Manifold 


The last way you can add seafoam in oil is to add this liquid to the intake manifold or vacuum lines to clean the valves. This can be a bit harder to use since you have to disconnect your vacuum line in your vehicle.in addition, you need to find the vacuum line that feeds the intake manifold and the cylinders.


The two vacuum lines that typically connect to the intake manifold are the PCV hose and the vacuum brake booster line – think about adding seafoam in oil to one of these hoses. If you are not sure how to do this or how to locate these lines, you should bring your vehicle to a local mechanic or auto body shop so they can identify the vacuum lines. 


In addition, seafoam can be added directly into the vacuum line while running at an operating temperature. When you add the seafoam in oil, you pour it in slowly so you do not harm or stall the engine. Once you have poured in about ⅓ of the seafoam in oil, turn off the engine and let it sit for around 5-10 minutes.  


Adding seafoam in oil can help you keep your engine, crankcase, fuel system, and lifters remain in high operating conditions for a long time! Seafoam in oil ensures contaminants do not build up over time and keep the transportation lines clean for efficient and quick travel of fluids.
