CITGO Synthetic Gear Lubricants are heavy-duty, synthetic gear and bearing lubricants designed for use in manual transmissions, transfer cases and differential axles of trucks, farm tractors, construction, passenger cars and miscellaneous industrial equipment. Blended from very high viscosity index, low pour point synthetic base stocks, these oils provide maximum protection to gears and bearings operating over a wide range of temperatures, speeds and loads. Their superb resistance to oxidation provides the benefit of extended drain intervals. Available in three viscosity grades: SAE 75W-90, 80W-140 and 50.
