Sea Foam is a cleaner, lubricant and moisture controller for interior engine components of gasoline, diesel and ethanol engines. It is a 100 percent petroleum product safe for seals, gaskets, oxygen sensors, catalytic converters and engine parts.
Sea Foam treatment cleans carburetors, fuel injectors, and carbon, varnish and gum deposits. The additive also removes moisture from fuel tanks and oil crankcases. It achieves this by solubilizing small water amounts from fuel. Sea Foam lubricates the engine to compensate for the deficiency created by fuel additives such as ethanol, which deprive the engine of lubrication. Sea Foam works through direct addition into fuel or combustion chambers on two-cycle and four-cycle rotary engines.
