High-performance polymeric dispersant designed for superior soot and sludge control in engine oils.
Excellent low-temperature performance with enhanced cold-start dispersancy and viscosity stability.
Compatible with conventional, synthetic, and low-SAPS (Sulfated Ash, Phosphorus, Sulfur) base oil systems.
Provides robust oxidation resistance and contributes to extended oil drain intervals.
Enables formulation flexibility with balanced detergency, dispersancy, and shear stability.
API SP/CK-4 and earlier gasoline and diesel engine oils.
Heavy-duty diesel engine lubricants for on- and off-highway applications.
Low-viscosity fuel-efficient engine oils (e.g., SAE 0W-16, 5W-30).
Extended-drain commercial vehicle lubricants requiring high soot-handling capacity.
