What is Seafoam

Seafoam is made up of formula and people have used it over the years to help improve their cars performance. There are a lot of uses for seafoam so you can find out where your car is lacking and use seafoam to better improve it.

What Can Seafoam Be Used For?

Seafoam can be used as a fuel additive – these are compounds that are formulated to enhance the quality and efficiency of fuels used in your car. They increase the fuel’s octane rating and can act as corrosion inhibitors or lubricants, therefore, allowing the use of higher compression ratios for greater efficiency and power.

Usually, older cars benefit off fuel additives live seafoam because they can reduce carbon build-up in your engine. Over time, Carbon gets deposited get built up in your engine and they are a natural by-product of burning gasoline in gasoline engines. This build-up can reside in the intake valves, combustion chambers, injector nozzles, and pistons of the engine which can rob it of power and performance.

If the carbon build-up is left inside your engine, this can cause more wear on your engine and it can clog your fuel systems which are known to cause a misfire and it can put your engine in a dangerous position. Seafoam can help to collect these deposits that reside all over your car’s engine and remove them safely.

Since Seafoam is liquid, it’s a better option for cleaning your engine rather than taking apart the whole engine just to clean it. This can be time-consuming and it can cost a lot of money – that’s what makes seafoam (View on Amazon) such as a good alternative to cleaning your car’s engine.

How to Use Seafoam

You now know the uses of seafoam and how it can benefit your car, but there are certain ways you need to apply It in order for your car to use it efficiently. There’s also a correct amount of seafoam you need to use depending on where you’re going to use it.

Oil Treatment

If you want to treat your engine of carbon deposits or clean oil sludge, then you want to use the correct amount of seafoam that will ensure that these deposits are cleaned away from your engine. To ensure that your engine is cleaned properly, you should use 8 quarts of seafoam per treatment that you want to give your car. A can of seafoam has 18 quarts so one can treat your car twice.

To treat your oil properly, you want to pour 1/3 of the seafoam into the oil filler tube 100 miles before you change your oil. You’ll need to run it for some time so it can work its way through the internals of your engine but not for too long as it can be counterproductive.

Fuel Additive

Another way to use seafoam is to pour it into your gas tank to clean up your fuel systems. Cars that have been used for a long time have systems that are dirty, and seafoam can do a great job to clean it up. Your fuel systems are made up of a lot of different parts and they have tiny passages that can get clogged, e.g. the fuel injectors.

You can experience issues with your engine such as misfire if any part of your fuel system is damaged. To clean your fuel system, you can pour seafoam into the tank just before you go to the gas station and fill it up. When you fill-up your tank, the seafoam will mix in with the gas and start to clean your fuel system – the fuel injectors are the main part of the fuel system you’re trying to target.


Another way to use seafoam is to clean your intake system. Your intake system is a set of components that allow the internal combustion engine to inhale, in the same way that the exhaust system allows it to exhale. The intake system is crucial to the function of your engine – it can collect air and direct them to individual cylinders.

Over the years your intake system can get really dirty and a lot of carbon deposits can build up over time. If your intake system is dirty, this can cause a lot of problems to the engine and can cause problems like misfires.

To clean your intake system, you should remove the hose in front of the throttle body and get someone to start the cat and rev it to 2000 rpm. Whilst the car is running, you should pour the seafoam spray into the intake system. If you pour too much seafoam, you’ll notice that your engine RPM will start to decrease. You want to pour as much seafoam as possible without your engine dies and drops too many RPMs.

Looking After Fuel System and Engine

Along with seafoam, there are many other ways that you can be maintaining your vehicle. The fuel systems and engine need to be checked and service often if you want them to have a healthy life. If you don’t do this, parts will get work out and you’ll find yourself spending lots of money at the mechanic.

If you want to avoid engine and fuel-related problems and save $100s of dollars that you’ll spend at the auto repair shop, you’ll need to service your vehicle often – you can use our mechanic-rated Auto Maintenance and Repair Manual to do this.

How Seafoam Can Improve Your Car

Since there are a lot of ways you can use seafoam, you should be pleased to know that there are a lot of benefits that come with using it. If your engine is old and you’ve had your car for a few years now, after using seafoam, you should start to notice some great improvements in your car.

Healthy Engine

The first thing you should notice is that your engine is quieter and healthier. Without the carbon build-up and oil sludge, your engine’s components should allow your engine to run more smoothly.

Better Fuel Efficiency

The most noticeable thing is fuel efficiency. Since your fuel system is now clean, you might get an improved efficiency because of less friction in your crankcase. If you used seafoam in the fuel, you might get a better fuel to air mixture which will improve your fuel efficiency.

Reduced Emissions

Because of less friction in your car engine system, your car is less likely to give off emissions through the exhaust. This will be good for the environment and your car should perform better in future emissions tests.

Higher Performance

Since your engine’s systems are now clean, you might get a better performance out of it. In combination with the air to fuel mixture and the lesser friction, you might get a better boost out of your engine when you’re accelerating.
