Does SeaFoam Work? Directions and Treatment Recommendation

For more than 70 years, SeaFoam has been going strong and is one of the most reliable engine treatments. Sea Foam, as a brand, makes several different products, but the most reliable of them all is the Sea Foam Motor Treatment.

The seaFoam fluid is developed to re-liquify the sludge, gum, carbon deposits, carbon buildup, and varnish build up slowly and safely in those hard parts of your car’s engine. The fluid does it so these buildups can be flushed out of your vehicle’s system.

So, if you are in doubt that SeaFoam works or not, you need to think there is a reason why this product has been in the market for so many decades and is still going strong.

Where Can You Use Sea Foam?

Sea Foam conveniently keeps the moving parts of your engine lubricated along with the fuel system of your car. Varnish develops due to ethanol additives that dry out the seals. It becomes difficult for oil to lubricate some parts as it halts the overall function of the system.

When the oil varnish by any fuel additive is gone, the engine gets back into its top working condition. Plus, within the fuel tank, Sea Foam can absorb water and stays burned up inside the combustion chamber without a problem and keeps it in working order.

There are three different options to use this Sea Foam Motor Treatment. You can use it in your vehicle’s crankcase, in its fuel tank, or its fuel filter (diesel). It works for gas tanks as well as a diesel fuel tank. If you are looking to clean the top end, use Sea Foam spray as per the directions given.

Still thinking does it work or not: here’s a video link that establishes this fact.

Sea Foam in the Crankcase

When you add Sea Foam to the crankcase, it will start cleaning gum and sludge along with the varnish. You will notice, if your engine is noisy, it will stop making those noises from the quiet noisy lifters. Just a single can of this fluid can conveniently treat up to sixteen quarts of oil.

Therefore, you are getting two treatments for one for a range of different vehicles. The best way to get the most out of it is to add the fluid at least 500 to 1000 miles ahead of your vehicle’s next oil change. You can add the rest of it right after the oil change.

Doing so will get rid of the sludge and varnish out. While the second treatment will keep things clean further. You can pour up to 1 oz of this fluid per quart or your engine oil, and you will end up using half of the bottle. Keep the rest of it for use after the oil change.

Sea Foam in the Fuel System

With your bottle of Sea Foam, you can conveniently treat up to 16 gallons of fuel as well. It is highly effective in getting rid of sludge development, carbon deposits, and carbon buildup inside the fuel system. Sea Foam can get rid of these deposits from your fuel injectors and fuel pump.

Therefore, it is a highly effective fuel injector cleaner. Being a fuel injector cleaner, it can get rid of any residues from the fuel injectors to ensure the system remains clear of any issues.

Hence, it can control the moisture level inside the fuel system and stabilizes the overall performance of the fuel. Apart from that, for diesel engines, it can work as a de-icing agent because it has anti-gel characteristics.

How Can I Use Sea Foam Spray?

As we have mentioned, you can use Sea Foam spray for cleaning the top end, but let’s discuss this matter in a bit more detail.

Does Seafoam Work

For cleaning those carbon deposits and carbon buildup from your vehicle’s air intake systems, combustion chambers, and intake valves present inside your car engine, including those GDI engines, Sea Foam spray is recommended.

There is no difference in the development formula of the Sea Foam from Sea Foam spray. The only difference is, it comes in an aerosol spray and not in liquid form.

You can use the Sea Foam Spray by inserting the application hose that comes with your purchase of this spray; it also includes a Hook Tool with a patented design. You just need to insert it in the air intake valves right in front of the plates inside the throttle body and spray the content inside it.

Begin by starting the engine and allowing it to warm up to its operating temperature. Now, increase your vehicle’s idle speed to 2000 RPM and start spraying into the engine. Then shut your engine off and let it hot soak the fluid for about 15 minutes.

After that, you can restart your engine and road test with aggression for clearing out the exhaust. For the road test, you will have to drive for about 5 to 10 miles for better results. Besides that, you can follow the directions given on the Sea Foam spray bottle.

You might have noticed; this is a bit of difficult treatment. But if you do some prep work, you can restore the power performance, whether it’s a small sedan or big rig gallons of diesel.

  • Cleaning fuel injector cleaning machines, you can mix it with gasoline in equal proportions.
  • Cleaning diesel fuel system injector cleaning machines fully requires Sea Foam.
  • Priming diesel fuel filters also require 100% Sea Foam.
  • 2-stroke pre-mix also requires 2 oz of Sea Foam per gallon of fuel.
  • If you want to stabilize fuel for storing it, you need to use Sea Foam 1 oz per gallon of fuel, and your fuel will remain stable for storage for up to 2 years.
  • For the trucks and cars that are driven frequently, Sea Foam can be used for every 3000 miles.
  • You need to add Seafoam whenever you refuel your small engines.
