55 GALLON DRUM Shell Spirax HD 85W-140 Heavy Duty Extreme-Pressure Gear Oil

This oil is designed for heavy-duty and conventional differentials in heavy and light duty trucks and passenger cars, conventional and heavy-duty manual transmissions, oil-lubricated wheel bearings, and drive-train gears in heavy-duty automotive, trucking, and off-road equipment. It is also suitable for industrial gear sets where extreme-pressure gear oils are required.

Cars equipped with limited-slip differentials may require a different lubricant specified by the manufacturer — Shell Spirax LS is noted as one such alternative. Check your vehicle manufacturer's recommendation before using this product in a limited-slip application.

Yes, this is a multi-viscosity oil formulated for year-round use across a wide temperature range, so it does not need to be switched out seasonally. Confirm that the 85W-140 viscosity grade matches your vehicle or equipment manufacturer's specification, as this is a heavier grade than the 80W-90 variant also available in the Shell Spirax HD line.

This oil is compatible with other automotive gear oils, so topping off or a partial drain-and-fill alongside existing gear oil is acceptable. For best performance, a full drain and refill with fresh oil is generally preferred when changing lubricants.

This oil is formulated for hypoid, spur, bevel, helical, spiral-bevel, and worm gears found in differentials, transmissions, final drives, and steering mechanisms. It specifically protects hypoid gears against wear and scuffing, and its sulfur/phosphorus additive system provides excellent load-carrying capacity under high-speed/shock load, high-speed/low torque, and low-speed/high torque conditions.

Beyond extreme-pressure protection, this oil contains additives that inhibit oil oxidation and help keep lubricated parts clean, as well as inhibitors that protect against corrosion, rust, and foaming — helping to extend the service life of gears and related drivetrain components.
