Ester/PAO base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear Full-synthetic formulas created from polyol ester/PAO base stocks, offer excellent lubrication under extreme conditions High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change Exceed API GL-5 specifications
