Full Synthetic Hypoid Gear Lubricant
The SAE 80W-140 is a premium heavy-duty, extreme pressure (EP), 100% synthetic GL-5 gear lubricant. It is compounded using a synthetic base stock which has a high viscosity index and an exceptionally low oxidation, and corrosion inhibitors to protect gears and bearings operated under a wide variety of load conditions. The high and low temperature performance of this product exceed those of conventional SAE 80W-90, SAE 90, and SAE 85W-140 hypoid gear lubricants.
