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
Exceed API GL-5 specifications
