Reliable Protection for High-Performance Marine Engines

CHEMPOL 5956 is a purpose-built additive package tailored for use in four-stroke marine engines, particularly those operating with modern emissions systems. Designed to meet the NMMA FC-W Catalyst Compatible specification, this formulation provides robust protection for gasoline-powered sterndrives and inboards—especially those equipped with catalytic converters.

Engineered for marine-specific challenges, CHEMPOL 5956 protects against the harsh effects of water exposure, salt corrosion, and long idle periods, while also supporting smooth performance at high RPMs. It's a balanced blend of detergent, anti-wear, and antioxidant components that ensures clean engine operation and long oil life under demanding conditions.
