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

When you put away your mower, snowblower, ATV or boat for the season, today’s ethanol-blended gas can start breaking down in as little as 30 days. That means clogged carburetors, hard starts, and costly repairs when you pull your equipment back out.

AMSOIL Gasoline Stabilizer keeps fuel fresh for up to 12 months, preventing varnish and gum buildup that Sea Foam can’t fully protect against. In independent corrosion testing, AMSOIL provided far better defense against rust and deposits, helping your engines start easier and last longer.

Whether it’s a weekend toy, work truck, or your lawn tools, AMSOIL gives you reliable protection that saves time, money, and frustration.
