Description

Red Line High-Performance Gear Oil is a full-synthetic formula blended with ester base stocks for shear stability, less gear noise, and more consistent viscosity in warm and cold temperatures. It contains extreme pressure (EP) additives for hypoid gears and friction modifiers for limited-slip differentials. It is not for use in most manual transmissions with synchronizers, as the slipperiness may cause gear clash. It exceeds API GL-5 specifications.
