Sea Foam Motor Treatment is a 100% pure petroleum product that safely and effectively cleans internal fuel and oil system components, helping your gasoline or diesel engine run cleaner and more efficiently. Sea Foam is an EPA-registered product, and will not harm engine components, seals, gaskets, catalytic converters or oxygen sensors.
Sea Foam liquefies gum and varnish deposits or internal engine contaminants, removing carbon deposits, freeing sticky valve lifters and rings, improving idle quality, pinging and hesitation problems. By using Sea Foam to eliminate varnish and carbon buildup, mechanics can more accurately diagnose mechanical problems that may exist. That is why Sea Foam has been so popular with professional mechanics for over 65 years.
As a fuel system additive, Sea Foam will clean carburetors,fuel injectors, clean carbon, gum and varnish deposits, add lubricity to fuel, stabilize fuel for 2 years and control moisture.
As an oil system additive, Sea Foam controls moisture, gum, varnish and residue deposits.
Using in crankcase oil
Sea Foam Motor Treatment may be used in an oil crankcase 2 separate ways, depending on your needs and expectations. Sea Foam Motor Treatment is most commonly used as a pre-service, old oil residue re-liquefier / cleaner and moisture drier. It can also be used as an after-service oil additive. In either application, Sea Foam Motor Treatment will safely and slowly re-liquefy old oil residue. Each method is described below:
Sea Foam is safe to use with all synthetic oils. 100% synthetic oils, and blends of synthetic and petroleum-based oils, were engineered and are manufactured to be 100% compatible with petroleum based oils, all brands, and vice/versa. Without this compatibility, oil manufacturers and engineers would be liable for the results of mixing non-compatible lubricants. Since Sea Foam ONLY contains petroleum oils, it is entirely compatible with synthetic oils.
Remember! When Using Sea Foam in Your Crankcase:
Uses in all fuels
Sea Foam Motor Treatment #s SF-16 (16 ounce), SF-128 (gallon container) and SF-55 (a 55 gallon drum) is used as a fuel additive in Gasoline, Ethanol Blends, Gas/oil mixes & ALL Diesel fuels. This includes all brands and grades of available fuels.When added to these fuels, Sea Foam Motor Treatment was specifically designed to safely do five (5) important tasks for you. They are:
Type of Fuel
Recommended Average Mixture
Normal gasoline grades (including 10% and 15% ethanol blends)
1 oz. Sea Foam Motor Treatment per gallon of gasoline
Can mix up to 2 oz. per gallon of gasoline if necessary. Mixing at less thantwo-thirdsoz. per gallon will impair the effectiveness of Sea Foam.
Diesel fuel (including low sulfur and ultra-low sulfur blends)
1 oz. Sea Foam Motor Treatment per gallon of diesel fuel
Can mix up to 2 oz. per gallon of fuel if necessary. Mixing at less thantwo-thirds oz. per gallon will impair the effectiveness of Sea Foam.
For FACTORY-DESIGNED E-85 Fuel engines
2 oz. Sea Foam Motor Treatment per gallon of gasoline
2-cycle, gas/oil mixed fuel engines
