AMSOIL vs. Sea Foam

The simple act of storing seasonal equipment can wreak havoc on an engine, leading to lost time and expensive repairs, not to mention a solid dose of frustration. Why? Because gasoline begins to break down in as few as 30 days. Varnish and gum begin to form, clogging tiny fuel passages inside the carburetor or injectors. In addition, components of the fuel system can corrode and not function properly. For these reasons, when storing seasonal equipment, like a snowblower in the spring or lawn mower in the fall, using a fuel stabilizer is essential. But what product will provide the most reliable protection for stored engines, AMSOIL Gasoline Stabilizer or Sea Foam Motor Treatment?

As the graph below shows, AMSOIL Gasoline Stabilizer provides fuel stability that Sea Foam Motor Treatment can’t match, helping maintain startability and protect against the formation of varnish and gum.

Our stabilizer keeps fuel from deteriorating for up to 12 months, allowing easier startups. It resists the formation of varnish and gum to keep fuel systems and storage tanks clean. It’s effective in ethanol-blended fuel and ideal for all two- and four-stroke engines, including motorcycles, snowmobiles, boats, ATVs, edgers, tillers, mowers, cars, trucks, snowblowers, chainsaws, generators and farm and construction equipment.

AMSOIL provides corrosion protection that far exceeds Sea Foam Motor Treatment, helping maintain power and performance and keeping metal looking like new, even when subjected to salt water.  Check out the image below to see the difference between AMSOIL and Sea Foam in a head-to-head corrosion-protection test.

AMSOIL Gasoline Stabilizer can save you time and money. It helps reduce downtime and maintenance costs by preventing harmful deposits from forming in the tank and fuel system and eliminating the need to clean or replace carburetors after long-term storage.
