Shell Spirax S2 A 80W-90
Shell Spirax S2 A 80W-90 is a high-quality heavy-duty axle oil formulated to provide reliable protection and performance in a wide range of automotive drivetrain applications. Developed using high-quality base oils and specialised extreme-pressure additive technology, the lubricant delivers excellent protection against wear, corrosion and oxidation in heavily loaded gear systems. The oil is designed to meet the demanding requirements of automotive axles, transmissions and differentials operating under severe load conditions.
One of the key advantages of Shell Spirax S2 A 80W-90 is its strong extreme-pressure performance. The formulation includes specially selected additives that help protect gear teeth under high load conditions, particularly in hypoid gear systems where sliding contact between gear surfaces can generate high stress. These additives form a protective film on metal surfaces, reducing metal-to-metal contact and protecting gears from scuffing, pitting and wear. This helps maintain drivetrain reliability and extend the service life of critical components.
Shell Spirax S2 A 80W-90 also offers excellent resistance to oxidation and corrosion. Drivetrain components may operate under elevated temperatures and may be exposed to moisture or contaminants during service. The lubricant’s advanced additive system helps resist oxidation and prevent rust formation on metal surfaces. By maintaining oil stability and preventing corrosion, the lubricant helps ensure long-term reliability and protection of axle and transmission components.
Another important benefit of Shell Spirax S2 A 80W-90 is its ability to maintain a stable lubricating oil film under varying operating conditions. The use of high-quality base oils ensures good low-temperature flow characteristics while maintaining adequate viscosity at high operating temperatures. This helps ensure effective lubrication across a wide temperature range and provides consistent protection for gears and bearings under both high-speed and low-speed operating conditions.
Shell Spirax S2 A 80W-90 is recommended for use in a wide range of automotive drivetrain applications. It is particularly suitable for automotive transmissions, differentials and hypoid axle systems subjected to moderate to heavy loads. The lubricant can also be used in gear units operating under a variety of load-speed conditions including high speed with shock loads, high speed with low torque and low speed with high torque. It may also be used in certain motorcycle gear units where the gearbox is separate from the engine.
The product meets the API GL-5 industry specification for axle oils and is designed to meet the lubrication requirements of many automotive manufacturers. Physical characteristics include a kinematic viscosity of approximately 146 mm²/s at 40°C and 14.7 mm²/s at 100°C with a viscosity index of approximately 100. The oil has a density of approximately 904 kg/m³ at 15°C, a flash point of approximately 175°C and a pour point of approximately –27°C, supporting reliable lubrication performance across a wide range of operating temperatures and drivetrain conditions.
