FR50 utilizes next generation synthetic oil technology to provide unmatched performance and protection in high temperature, high shear environments. FR50 provides the required viscosity for Ford Coyote oiling and variable valve timing systems while delivering the wear protection needed for performance cams. It also utilizes a low volatility formula that guards against oil vaporization and foaming. Eliminating this problem reduces oil consumption and prevents inconsistent cam phaser system performance. Ideal for crate up to super charged Ford Coyote engines. Viscosity typical of 5W-50.
