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.
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.
