Gl-5 Gear Oil 75W140 Ns. Popular for cars and light trucks like Ford Mustang and F-150, Toyota Tundra and Sequoia, Jeep Cherokee and Dodge Ram 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 engineered for use in most manual transmissions or transaxles, 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 and SAE J2360 These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change Stronger shear stability and reduced oxidation compared to other synthetics and conventional gear oils Exceed API GL-5 specifications Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
