CHEMPOL9012M is a high-performance Multi-Cylinder Lubricant (MCL) additive package designed for formulating premium engine oils for large two-stroke crosshead marine diesel engines. These engines are widely used in merchant vessels, container ships, oil and gas tankers, and other heavy-duty marine applications operating under extreme load and environmental conditions.
Its balanced chemistry provides strong lubrication, wear protection, and deposit control in high-pressure and high-temperature cylinder environments. It strengthens oil film, maintains piston cleanliness, and prevents liner scuffing and ring wear—enhancing overall engine performance, fuel efficiency, and reliability. CHEMPOL9012M can also serve as a TBN booster in formulating high TBN lubricants for four-stroke marine engines.
