Alright, at this point, you’ve been reading about things that you can do to help your car, and low and behold you’ve heard of this magical liquid… Sea Foam, or as it’s often written Seafoam. So what is this elixir of life for your car?

Don’t worry as we break it down because when we first heard of it we were blown away, like why wouldn’t we use it? The promises and how people talked about it made us go online right away to find out where to buy it. But after reading a bit more about it we felt it would be worth it to break down what it is, what it does, and some other useful information about using Sea foam in your car or truck.

What is Sea foam?

Sea foam is a multipurpose product that has been used by both automotive and marine mechanics for decades. It’s an effective cleaner and lubricant, designed to help keep engines running smoothly and efficiently. Sea foam can be added directly to your car or boat’s fuel tank or can be used as a top engine treatment for two-stroke engines. The product is also useful for cleaning carburetors, intake valves and combustion chambers in gasoline engines.

Chemical Composition of Sea Foam

Chemical Composition is an integral part of understanding what sea foam is and does. Sea foam is a commercially available product that’s been used for years in the automotive industry as a fuel system cleaner and lubricant. It’s main ingredients are petroleum distillates, mineral spirits, and benzene, all three of which have their own unique properties and qualities.

The petroleum distillates act as the solvent base to dissolve contaminants within fuel systems while the mineral spirits help clean out dirt build up from clogged injectors. Benzene on the other hand can act as a drying agent, helping to evaporate water from gas tanks or lines more quickly than what would normally happen with just air exposure alone. Together these three ingredients work together to create an effective cleaning agent that helps keep your vehicle running smoothly and efficiently.

So what does that really mean for you and what will happen when you use it?

Uses in Automotive Industry

Sea foam helps to break down carbon deposits build up in your car’s engine, which can cause poor performance, decreased efficiency and costly repairs. This product also helps to reduce friction and heat buildup while restoring lost power and compression. On top of this Sea foam has been used on newer vehicles to help prevent rusting of steel components by creating an additional barrier against corrosion in the vehicle’s cooling system. By using Sea foam when scheduled maintenance is due or when you feel like your car isn’t running at its best, it can help prolong the life of your car’s engine and keep it running smoothly for years to come.

These are all the things that made us run online and look for the places where I can buy it, but as the saying goes, if things seem to good to be true they can be…

Benefits of Using Sea foam

Sea foam is revered as a unique product which can be used to clean and protect the engine of your car. It is a versatile, inexpensive solution that can help extend the life of your vehicle and keep it running smoothly. In this article, we will discuss some of the key benefits of using Sea foam in your automobile.

First off, Sea foam is an effective tool for cleaning out built up deposits from vital components like fuel tanks and fuel lines. This means it can help improve or eliminate issues such as poor acceleration, rough idle, stalling or hard starting. Additionally, regular use helps reduce engine moisture build-up, which can lead to corrosion and other damage over time. Furthermore, Sea foam acts as a lubricant for spark plugs and upper cylinder walls which aids in smoother starts while also preventing wear on piston rings.

Drawbacks of Using Sea foam

Sea foam is a fuel additive often used to clean and protect engines, and has been used for a kind of cure all for a wide variety of issues people can have with their cars. While it offers several benefits, there are also drawbacks that need to be considered before use.

Sea foam can cause oil buildup in the engine which may result in clogs and increased pressure, because it can unlodge some gunk from one area and end up moving to somewhere else. This can lead to issues with spark plugs, resulting in a decrease in the performance of the engine. It should not be used on engines with high mileage as it will likely damage delicate parts such as valve seals and gaskets. The use of Sea foam can also make an engine significantly louder due to the additional pressure built up within the system, so this needs to be taken into account when using it on vehicles intended for quiet operation such as tractors or boats.

And this is one of the biggest complaints that we saw when we did more research is that people would use this product in super high mileage cars, or neglected engines, and sure it would clean things out… but would actually result in a negative outcome. This is because sometimes it’s better to leave things alone if they’re working alright. If you dislodge some sludge that was keeping a cracked part of your engine from leaking, what will happen? Well now you’ve got a leak.. but its very clean… I’d rather no leak personally.


Sea foam is a versatile and multi-purpose product that can be used to help solve a variety of automotive issues. But there are some bad things that can also happen once you do a deep cleaning of your fuel system. So it is really hard to say if it is worthwhile or not to use Sea Foam. For us, consistent maintenance will be a lot better off than using Sea Foam. Consistency will always beat peaks and valleys of effort. That is just how life is.

Sea foam is an effective, safe, inexpensive way to improve vehicle performance while protecting engine components from wear and tear. With its multi-purpose capabilities, it can help you get the most out of your vehicle without breaking the bank. But for us, we would only use it as a last resort, just because at that point if something goes bad, then it was going to break soon anyway. I wouldn’t use it just because I heard it will make my car run cleaner, as that just doesn’t make sense.
