Quicksilver four-stroke inboard engine oil 4L, superior corrosion protection

• Quicksilver Four-Stroke Sterndrive and Inboard Engine Oil is an exclusive formula specifically designed for four-stroke marine engines, providing superior lubricity and corrosion protection. This unique 25W-40 multiviscosity oil contains no viscosity improvers that could shear and compromise engine protection.
• A higher concentration of detergents, antioxidants, wear and corrosion inhibitors provides protection that far exceeds that of conventional four-stroke automotive oils.
• With continuous use, it reduces wear, abrasion and scoring of internal engine components, keeps pistons clean, prevents piston rings from seizing and protects engine components from corrosion.
• Quicksilver four-stroke oil meets and exceeds API maintenance requirements for SJ, CF-2, and CH-4 oils. Multifunctional additives ensure optimal performance for boating use and maintain warranty protection for all Mercury MerCruiser engines.
