If you want to ensure your snowblower runs smoothly, using the right fuel additive is crucial.

One of the best options available for your snowblower is Sea Foam Motor Treatment. This petroleum-based product is safe to use and offers a range of benefits.

Sea Foam stabilizes fuel for up to two years, reduces moisture in the fuel, cleans carburetor deposits and residues, and improves performance. It’s designed to prolong the motor’s life and protect against valve seat erosion and ethanol damage.

Other recommended fuel additives include GumOut Multi-System Tune-Up, PRI-G, and STA-BIL 360 Protection. These additives remove dirt and debris from your engine while enhancing its performance.

Let’s examine the best fuel additives for snowblowers in more detail below.

Key Takeaways

  • Stale gasoline is a common reason for snowblowers not starting after sitting for a while.
  • Sea Foam fuel stabilizer can be used in any snowblower gas engine and fuel system to stabilize fuel for up to two years and reduce moisture.
  • Sea Foam can clean carburetor deposits and residues, improving performance and extending the overall lifespan of engines.
  • Other recommended fuel additives for snowblowers include PRI-G, Marvel Mystery Oil, and STA-BIL 360 Protection.

Types of Fuel Additives

Fuel additives are designed to boost fuel properties and protect your snowblower’s engine from the harmful effects of ethanol in gasoline.

Here are four types that can help maximize your snowblower’s performance and longevity:

  • Solvent-Based Additives: These additives contain cleaning agents that dissolve dirt, varnish, and carbon deposits from the fuel system, improving fuel atomization and combustion efficiency.
  • Detergent Additives: Detergent additives remove deposits from carburetors, intake valves, and fuel injectors, providing superior cleaning power.
  • Combustion Enhancers: Combustion enhancers increase the speed of the flame and promote more complete burning of the fuel-air mixture, resulting in improved power output, throttle response, and reduced emissions.
  • Ethanol Treatment Additives: These additives prevent rust formation, inhibit oxidation, and eliminate water accumulation in the fuel tank. They also stabilize fuel for long-term storage and protect vital engine components.

To get the best performance from your snowblower, select a high-quality fuel additive that meets manufacturer specifications and recommendations.

Snowblowers are invaluable to keep your driveway clear in the winter. But, like any machinery, they can experience a number of issues.

A fuel additive can be a great solution to ensure your snowblower runs smoothly and lasts for years to come.

The recommended fuel additives below have been extensively tested and proven to enhance the performance of snowblower engines while protecting them from the damaging effects of ethanol and other contaminants.

Sea Foam Motor Treatment

Sea Foam is a petroleum-based product specifically designed for gas engines and fuel systems. It reduces moisture in the fuel, stabilizing it for up to two years. This is especially important for snowblowers that may be inactive for long periods.

Sea Foam also acts as a cleaner, removing carburetor deposits and residues to ensure optimal engine performance. It can clean intake valves, preventing erosion.

Finally, Sea Foam helps protect against the damaging effects of ethanol in gasoline. Ethanol can corrode valves and clog fuel pumps. Using Sea Foam regularly helps counteract these effects and keeps your snowblower running smoothly.

Reducing moisture in the fuel system, Sea Foam protects against fuel pump clogging and other engine problems.

To use Sea Foam, add two ounces for every gallon of gas in a one-gallon can. It’s recommended to use this fuel additive with each tank of fuel for maximum effectiveness.

Other Alternatives

  • Marvel Mystery Oil is a reliable option that not only acts as a fuel additive but can also be used in oil to clean and remove sludge.
  • GumOut Multi-System Tune-Up contains advanced PEA technology detergent that is more effective than traditional solvents.
  • STA-BIL 360 Protection is designed to remove water, prevent corrosion, and keep the entire fuel system clean.
  • Lastly, PRI-G is an excellent choice that restores stale or bad fuel back to working condition while preventing deposits in the engine and fuel system. 

Using these additives in each gas tank will ensure your snowblower runs optimally throughout the winter season.


So, there you have it — the best fuel additives for your snowblower.

Sea Foam Motor Treatment is the top choice due to its petroleum-based formula that ensures safety and compatibility with any snowblower gas engine. It stabilizes fuel for an extended period and tackles moisture, carburetor deposits, and residues while enhancing performance. 

Other recommended options include GumOut Multi-System Tune-Up, Marvel Mystery Oil, and STA-BIL 360 Protection.

Remember to avoid using diesel engine additives on gas-powered snowblowers to maintain smooth and efficient operation. 

Choosing the suitable fuel additive allows you to keep your snowblower running at its best all winter. Good luck!

Frequently Asked Questions

Can I use fuel additives designed for diesel engines in my gas-powered snowblower?

Using fuel additives designed for diesel engines in your gas-powered snowblower is not recommended. Diesel fuel additives are formulated differently and may not provide the necessary benefits or be compatible with your snowblower’s engine.

How often should I use fuel additives in my snowblower?

It’s best to use a fuel additive in your snowblower every time you fill up the tank. Doing so helps clean the fuel system, stabilize the fuel, and protect against moisture and corrosion.

Are there any fuel additives specifically designed to address ethanol-related issues in snowblowers?

Yes, there are. Sea Foam Motor Treatment is one such additive that can reduce moisture, clean carburetor deposits, and protect against the damaging effects of ethanol.

Are there any fuel additives that can help with fuel storage and water removal in my snowblower?

Fuel additives like Marvel Mystery Oil, GumOut Multi-System Tune-Up, Sea Foam Motor Treatment, and PRI-G can help with fuel storage and water removal in your snowblower.

Can fuel additives solve fuel leakage issues in my snowblower?

Fuel additives are not designed to solve fuel leakage issues in your snowblower. If you’re experiencing fuel leaks, inspect and address the source of the leak, such as a faulty fuel cap or other common areas of leakage.
