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?
How the Two Compare
As the graph below shows, AMSOIL Gasoline Stabilizer delivers 8X longer fuel stability than Sea Foam Motor Treatment in the triple-length gasoline oxidation stability test (ASTM D525), 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.
