SF/CD Engine Oil Additive is an engine oil additive designed to improve engine performance and service life. SF/CD refers to the American Petroleum Institute (API) engine oil classification system. SF means that the additive is suitable for use on gasoline engines, and CD means that the additive is suitable for use on diesel engines.
Such engine oil additives typically contain a combination of detergents, dispersants, antioxidants, and corrosion inhibitors. These additives help clean and protect the engine by removing deposits, reducing friction and wear, preventing sludge buildup, and inhibiting rust and corrosion.
SF/CD engine oil additives are typically used in older vehicles because they are formulated to meet the specific requirements of older, less advanced engine designs. Designed to improve engine oil performance and protection, these additives help reduce wear, prevent deposits and improve overall engine performance.
