Have you ever heard of cleaning your car’s engine oil and fuel system with sea foam? Want to know how to use sea foam in oil and fuel system of your car. A lot of people are confused regarding sea foam. They hold misconceptions about this product and its specific purpose or use.
Do you know that sea foam can enhance your engine’s performance by keeping it clean? Yes, you heard it right! And, this is more so if you own a high-mileage car. By using sea foam regularly on your car’s engine, you can protect your engine from the vicious carbon deposits over time.
Sea foam has been used for a long time as a cleaning agent for oil and fuel system. It is the only sure shot way to evade carbon deposits and keep your car’s mileage on top.
Sea foam is formulated specially to liquefy hardened varnish, sludge, carbon deposits and gum safely from engine parts so they can easily be flushed out. It lubricates all the moving parts, especially in the vehicle’s fuel system.
Ethanol additives in fuel dry the seals leaving behind a varnish. This makes it difficult for the engine oil to lubricate the parts. Sea foam helps to remove the varnish and return the engine to its pristine working condition. Sea foam is capable of absorbing water. Thus when used inside a fuel tank, it can burn up easily without any problem.
Due to fuel combustion carbon or the black colored soot collects on the cylinder wall, head, in the valves and piston. The deposits affect engine performance causing it to consume more oil. This leads to low fuel economy, difficulty in starting, engine knocking, more emission and overheating of engine.
When you notice idling problems, gunk in your engine oil, clogged injectors or very low fuel economy, using sea foam is the right solution. The sea foam additive helps take care of all the above mentioned issues. Here is a before and after picture of how effective sea foam is in clearing clogged valve.

Regular use of sea foam or other decarbonizing agents will help improve engine performance and give you a better mileage. But you need to use caution while using it, as it is a very powerful compound. That is why we have come up with this simple step by step guide to help you learn how to use sea foam in oil and fuel system:
Things You Will Need:
Before we move to the process of using sea foam, ensure you have all the right tools needed for adding the sea foam.
It is best to be prepared for changing the oil and spark plugs after the sea foam treatment, if you have a car with high mileage. And make sure the fuel tank is half full.
Warm the engine to allow it to reach operating temperature. As the engine is in operation, disconnect manifold vacuum lines that feed all the engine cylinders.
For a majority of cars, booster hose for brake is sufficient. Sea foam works well in cleaning up the intake and valves in the intake manifold.
You should first find the vacuum line and remove it from the intake manifold. The vacuum line going to the intake manifold is shown clearly in the below picture.
Alternatively, you can also use a sea foam spray, if there are no vacuum lines in your engine. When you pour sea foam into vacuum line, do it directly and with the car being powered up and running at the normal operating temperature.
Avoid passing the sea foam via check valve. In many vehicles like Nissan, the valve is found right in the center of the booster hose alongside the firewall.
To enable this, disconnect hose in such a way that check valve stays on hose that links to the brake booster.
Now use the hose that leads to the brake booster towards manifold.
Insert the smaller hose into the manifold until there is tight seal.
Instead of pouring sea foam directly into hose, which can cause sea foam to spill, dip the hose end into sea foam can.

If you do it right, the engine will stumble with each sip.
Keep running the engine but avoid giving too much of throttle. Ensure you are driving at the under 2000 rpm. Let the engine take in the sea foam in sips and not chug it.
To know you are doing the process right, look at the level of sea foam in the can. For the first 60 seconds half or at least 1/3 of the foam should be emptied.
You can see a white colored smoke emerging from tailpipe.
When you finish off nearly half of the can, dip hose fully into can and give a nice chug. Let the chugging stall your engine.
Or you can have an assistant off the engine at once. This will cause a layer of wet sea foam on the top of the cylinders and valves. This will allow the foam to soak well and dissolve all the accumulated varnish deposits that keep the carbon together.
Let the sea foam soak in the engine for about 30 minutes.
While the sea foam does its work on the engine, dump the remaining can into fuel tank using a funnel.
Restart engine and drive to a place where it is possible to push your car hard and fast.
Keep the windows closed so the stink does not get inside.
Make sure you do a 0 to 60 acceleration with a widely open throttle. And do it in an area where there is not much of traffic as you are going to let out plenty of smoke.
After a 7 to 10 mile drive park your car and let the engine cool down. Expect some amount of residual smoking and stink when you drive next. Don’t worry, it will go away.
Now we will use the other sea foam can. Use it to clean the oil residues and other contaminations in the crankcase, the oil rings and lifters and PCV system.
For the right amount of sea foam check with the owner’s manual you have. It will be usually 1 ounce for one quart oil.
If your oil capacity is 5 quart the amount of sea foam you use will be 5 ounce.

Although sea foam manufacturers recommend leaving it inside crank case until the next time you change the oil, it is best to change it after about 75 to 100 miles from the time you add sea foam. This is because engines that clock higher miles can easily have lots of accumulation which can affect the oil filter.
Now add the remaining half of sea foam in the crankcase after changing the oil. You can also add the sea foam in the fuel tank when you fill it up next.
In the fuel tank it can:
Add about one ounce for each gallon of gasoline. You can add the sea foam directly and drive on as usual.
If your tank has water in it, the sea foam will help to remove it too. If you want to use the sea foam to specifically remove water, use once ounce of sea foam for one gallon of fuel.
Don’t worry about leaving the sea foam in crank case alongside clean oil. It is perfectly safe and can help clean the fuel and injector system. In some cars, the sea foam has also removed deposits that lead to faulty readings in the fuel gauge.
