- Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions - High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change - Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears - Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils - Exceeds API GL-5 specifications - Enginee red to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear - Most popular Red Line gear oil, with thousands of applications for passenger cars, light trucks, and racing vehicles - Contains additional friction modifiers for suitability with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required - This product is not designed for use in most manual transmissions or transaxles in passenger vehicles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems - Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360, and Chrysler spec MS-9763
