Sea Foam: Definition and Benefits

Launched in 1942, Sea Foam is used to clean gasoline and diesel fuel systems. If fuel is left in a car’s system too long, it can to break down. When this happens, gummy residue forms on the fuel lines, fuel pump, carburetor and fuel injection lines. These deposits can negatively impact your car’s performance.

When to Use Sea Foam

When should you Sea Foam your car? It depends on how often you drive your vehicle.

Most of us drive our cars regularly. In this situation, fuel is used and replenished every two weeks or sooner. For maintaining the health of a vehicle that’s driven regularly, it’s a good idea to add one or two cans of Sea Foam to the fuel for every 2,000 to 5,000 miles that are driven.

If you use your vehicle less frequently, it’s recommended that you add Sea Foam to every tank of fuel. It’s especially important to add Sea Foam if you plan on storing your car for long periods. Engine manufacturers will tell you that unprotected fuel will start to degrade within 30 days, and this can harm some of your vehicle’s most vital components. Sea Foam works to prevent this degradation from taking place, and protects the integrity of your car’s fuel system.

Sea Foam breaks down buildup that occurs in your car’s fuel system, but it can also prevent these deposits from forming. For this reason, regular use is recommended to prevent future problems.
