SHELL SPIRAX S4 AX 85W-140 12*1QT CASE

Shell Spirax S4 AX 85W-140 is a high-performance heavy-duty automotive gear oil, specifically designed for use in extreme-pressure (EP) applications. It offers exceptional protection for hypoid gears, ensuring long-lasting durability in severe service conditions. The oil’s advanced EP additives provide superior load-carrying capability, significantly minimizing wear and scuffing, even under the toughest operating conditions. With excellent thermal and oxidation stability, Shell Spirax S4 AX 85W-140 maintains its protective properties, preventing the formation of deposits and ensuring clean bearing surfaces for optimal performance.

One of the key advantages of Shell Spirax S4 AX 85W-140 is its ability to resist high-temperature breakdown, even in conditions reaching up to 150°C. This superior thermal stability ensures that the oil continues to protect gears and critical components, reducing the risk of overheating and mechanical failure. Its all-season performance capabilities make it an ideal choice for year-round use, eliminating the need for seasonal gear oil changes. This versatility not only enhances convenience but also reduces operational costs by minimizing the number of gear oils required.

In addition to its superior protection, Shell Spirax S4 AX 85W-140 contributes to improved fuel economy by reducing frictional losses in the drivetrain. Its multigrade properties allow for better lubrication across a wide range of temperatures, making it suitable for both heavy-duty equipment and passenger vehicles. The oil is recommended for use in a variety of gears, including hypoid, spur, bevel, helical, spiral-bevel, and worm gears, making it highly versatile for different drivetrain systems such as differentials, transmissions, and final drives
