MR50 is a unique 15W-50 synthetic performance marine oil. MR50 features a high zinc content to protect aggressive cam profiles, and the advanced synthetic formula delivers high temperature protection from viscosity breakdown. However, High Performance Marine engines require more than extra anti-wear protection. These engines also need defense against moisture. Joe Gibbs Driven MR50 delivers rust and corrosion inhibitors as well as increased anti-wear additives.Excellent protection for high performance marine engines
Rust inhibitors for winter storage and defense against ethanol blended fuel
High Zinc Content - Higher level of Zinc (ZDP) delivers proper anti-wear protection for high output engines and flat-tappet camshafts.
Extra Film Thickness - Advanced synthetic technology for greater film thickness under high temperatures and high loads.
Thermal Stability - Defends against oil consumption and viscosity breakdown. Ideal for blown big block engines.
Storage Protection - Defends against moisture drawn into the engine by modern bio-blended fuels. Utilizes a tenacious oil film technology developed for the U.S. military.
Ideal for flat-tappet cams, big blocks and blown marine engines
