AMSOIL vs. Sea Foam: Which Fuel Stabilizer Protects Your Engines Best?

Storing seasonal equipment — whether it’s a snowblower, lawn mower, motorcycle, or even a generator — can cause major headaches if you’re not protecting your fuel. Gasoline starts breaking down in as little as 30 days, forming varnish and gum that clog fuel passages and corrode sensitive engine components. That leads to hard starts, costly repairs, and lost time when you need your equipment most.

That’s why a fuel stabilizer isn’t just “nice to have” — it’s essential. But the big question is: which product does the job better, AMSOIL Gasoline Stabilizer or Sea Foam Motor Treatment?

How AMSOIL Outperforms Sea Foam

Independent testing makes the answer clear:

  • Longer Fuel Stability – AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, far longer than Sea Foam. That means easier starts after storage and less risk of fuel system clogs.

  • Superior Deposit Protection – It resists varnish and gum buildup, keeping fuel systems, storage tanks, and injectors clean.

  • Broad Compatibility – Works in ethanol-blended fuel and in all types of equipment — two-stroke or four-stroke, big or small. From motorcycles, ATVs, and boats to chainsaws, lawn mowers, trucks, and snowblowers, AMSOIL delivers consistent protection.

Corrosion Resistance You Can See

Engines and storage tanks don’t just battle varnish — they’re also vulnerable to corrosion, especially in harsh or wet conditions. AMSOIL provides far greater corrosion protection than Sea Foam, proven in lab and real-world testing. Even in saltwater exposure, AMSOIL keeps metal looking like new, preserving both performance and longevity.

Why It Matters for You

Using AMSOIL Gasoline Stabilizer isn’t just about protection — it’s about saving time and money:

  • Prevents costly carburetor rebuilds or replacements after long storage.

  • Reduces downtime by ensuring equipment starts when you need it.

  • Extends the life of your investment, whether it’s a weekend toy or critical work equipment.

Bottom line: While both AMSOIL and Sea Foam claim to stabilize fuel, only AMSOIL Gasoline Stabilizer consistently delivers the long-term protection, corrosion resistance, and reliability you can count on.
