Sea Foam is a petroleum-based product used to clean and lubricate fuel systems. It is safe for all engines and can be added to fuel in varying concentrations, depending on the desired level of cleaning. While Sea Foam is generally effective in cleaning fuel systems, there have been some reports of engine issues arising after its use. In some cases, Sea Foam may loosen sediment in the fuel tank, which can then pass through the fuel pump and cause damage. Additionally, using too much Sea Foam or not diluting it sufficiently with fuel can lead to engine problems such as stalling, misfiring, and warning lights. Therefore, it is important to follow the recommended dosage and usage instructions to avoid potential issues.

What You'll Learn
Seafoam can clog fuel injectors
Seafoam is a petroleum-based product marketed as a fuel system cleaner. It can be used in both gasoline and diesel engines and is claimed to clean and lubricate the entire fuel system, including fuel injectors. However, there are mixed reviews about its effectiveness in cleaning fuel injectors. While some people have reported positive experiences, others have questioned its ability to thoroughly clean injectors.
Seafoam is added directly to the fuel tank, and the recommended dosage is 1 ounce per gallon for regular maintenance. For cleaning, a higher concentration of Seafoam can be used, with the instruction manual stating that "the more Seafoam you add to fuel, the better it cleans!" It is also recommended that users wait until the tank is low (1/4 to 1/8 full) before adding Seafoam and then driving until the tank is almost empty before refuelling.
There are reports of people experiencing issues with their vehicles after using Seafoam. Some have reported that their cars would not start, while others have described issues like heavy squeaking and stalling. In one case, a user reported that their car produced a "bubbling sound" when trying to start it after using Seafoam. However, a mechanic suggested that the issue might be unrelated to Seafoam usage and could be due to other factors.
One of the potential concerns with Seafoam is its ability to loosen sediment in the fuel tank. This loosened sediment can then get through the fuel pump and potentially cause damage. Additionally, Seafoam is primarily composed of isopropyl alcohol and paint thinner, which may not be effective in thoroughly cleaning fuel injectors.
To effectively clean fuel injectors, it may be necessary to remove them and clean them using a dedicated parts cleaner or an ultrasonic cleaner. Alternatively, a carb cleaner can be connected to the injector, and the injector can be pulsed with a 12V battery while pressing the can nozzle. In some cases, it may be more cost-effective to simply purchase new fuel injectors or send them to a specialist cleaning service.

Seafoam can cause misfiring
Seafoam is a petroleum-based product used to clean fuel residues and deposits from engines. It is generally considered safe to use and can be added to fuel tanks to improve engine performance and fuel efficiency.
However, in some cases, using Seafoam may lead to engine misfiring. While Seafoam is intended to clean engines, the process of cleaning can sometimes result in the dislodging of carbon buildup, which can then coat valve stems and cause intake valves not to close properly. This, in turn, can lead to engine misfiring and other issues.
In one case, a user reported that after using Seafoam, their car would not stop misfiring and that their gas mileage was suffering as a result. A possible explanation for this issue was that the Seafoam had cleaned away carbon buildup, which was previously helping to keep compression high. With the carbon buildup removed, the engine began to misfire.
Another user reported a similar issue, stating that after using Seafoam, their car began to experience heavy squeaking and then stalled out. In this case, it was suggested that the Seafoam may have loosened sediment in the fuel tank, which then got through the fuel pump and damaged it.
It is important to note that these issues appear to be relatively rare and that Seafoam is generally considered safe to use. However, it is always a good idea to be cautious when using any type of chemical cleaner in your engine and to follow all instructions and guidelines provided by the manufacturer.

Seafoam can cause backfires
Seafoam is a fuel additive designed to clean and lubricate your fuel system. It is meant to be used as a maintenance product or to solve a problem. However, there are some risks associated with using Seafoam, and one of them is that it can cause backfires.
Seafoam is generally considered safe to use in both gasoline and diesel engines and can be added to fuel tanks, oil crankcases, and directly into the intake. It is meant to clean carbon build-up, remove moisture, and stabilize fuel. The more Seafoam you add to the fuel, the better it cleans.
However, there are some potential issues to be aware of when using Seafoam. One of them is that it can cause backfires. This is because Seafoam raises the exhaust gas temperature (EGT), which can lead to backfires. In addition, if too much Seafoam is added to the fuel, it can cause drivability issues and damage fuel system components.
It is important to follow the instructions on the Seafoam can and not exceed the recommended dosage. It is also a good idea to make sure that there is nothing near the exhaust manifolds that could burn, as the increased EGT can pose a fire risk.
In conclusion, while Seafoam can be an effective fuel additive, it is important to use it correctly and be aware of the potential risks, including the possibility of backfires.

Seafoam can cause a burning smell
Seafoam is a petroleum-based product used to clean and lubricate fuel systems. It is considered safe and effective for all types of gasoline, diesel fuels, and fuel blends.
While Seafoam is generally regarded as a reliable fuel additive, in rare cases, it can cause a burning smell. This smell can be distressing and may interfere with daily life.
There are several potential causes for this burning smell. One possibility is that the Seafoam has loosened up sediment in the fuel tank, which has then passed through the fuel pump and caused damage. This can result in fuel pump issues, leading to a burning smell.
Another potential cause could be related to the nose or nasal cavity. Conditions such as chronic sinus infections, allergic rhinitis, or non-allergic rhinitis can lead to phantosmia, a condition that causes olfactory hallucinations, or phantom smells. Phantosmia can result in detecting unpleasant, foul, or burning odours that are not actually present in the environment.
Additionally, in rare cases, Seafoam-related issues could indicate a more serious underlying problem with the vehicle or engine. For example, a faulty fuel pump or fuel pressure issues could be the root cause of the burning smell.
If you experience a burning smell after using Seafoam, it is recommended to consult a mechanic or a healthcare provider, depending on the specific situation and symptoms. They can help diagnose and address the issue, ensuring the proper functioning of your vehicle and your peace of mind.

Seafoam can cause a warning light to come on
Seafoam is a petroleum-based product used to clean fuel systems. It is added to the fuel tank to clean and lubricate the fuel system. While it is generally safe to use, in some cases, it can cause issues that trigger a warning light.
Seafoam is known to loosen sediment at the bottom of the fuel tank, which can then get through the fuel pump and damage it. This may result in reduced fuel pressure and cause the check engine light to come on. In such cases, it is recommended to check the fuel pressure and ensure that the fuel pump is functioning properly.
Additionally, using too much Seafoam in the fuel tank can lead to problems. It is recommended to use one ounce of Seafoam per gallon of fuel for regular maintenance. However, for cleaning, a higher concentration can be used, such as two ounces per gallon. Using too much Seafoam can lead to drivability issues and may be the reason for the warning light.
In some cases, Seafoam may not be the direct cause of the issue, but it can loosen up existing deposits, leading to problems that trigger the warning light. It is important to read and follow the instructions on the Seafoam can to avoid using too much or too little.
If issues persist after addressing the potential causes mentioned above, it is advisable to consult a professional mechanic for further diagnostics and repair.
