Shell Spirax S3 AM 80W-90
Shell Spirax S3 AM 80W-90 is a high-performance universal driveline gear oil developed to provide reliable lubrication and protection for both gearboxes and axle systems in heavy-duty vehicles. Formulated with specially optimised mineral base oils and advanced additive technology, the lubricant is designed to deliver excellent wear protection, strong oxidation stability and extended oil drain capability. Its universal formulation allows a single lubricant to be used across multiple drivetrain components, helping simplify maintenance and lubrication management for vehicle fleets and equipment operators.
One of the key advantages of Shell Spirax S3 AM 80W-90 is its universal gear oil formulation. The product has been specifically designed to meet the lubrication requirements of both gearboxes and axles, allowing it to be used across the entire driveline. This capability reduces the need for multiple lubricants within the same vehicle or fleet, helping streamline maintenance processes and reduce the risk of misapplication.
Shell Spirax S3 AM 80W-90 also provides excellent protection against wear and gear surface damage. The advanced additive system forms a strong lubricating film between metal surfaces under high load conditions, helping protect gears and bearings from pitting, scoring and scuffing. This improved protection helps prevent premature component failure and contributes to longer gear life in both gearboxes and axle systems.
Another important benefit of Shell Spirax S3 AM 80W-90 is its high resistance to oxidation and thermal degradation. Drivetrain systems often operate under high temperatures and heavy mechanical loads which can accelerate lubricant degradation. The formulation helps resist oxidation and prevent the formation of harmful deposits within gearboxes and axles. This helps maintain oil cleanliness and ensures reliable lubrication performance throughout extended oil service intervals.
Shell Spirax S3 AM 80W-90 also features a modern low-chlorine formulation which improves recyclability and supports environmentally responsible lubricant management. This formulation helps reduce environmental impact while maintaining the high-performance protection required for demanding drivetrain applications.
The lubricant is recommended for use in heavily loaded automotive transmissions and axle drives, including synchronised and non-synchronised heavy-duty gearboxes. It is suitable for use across a wide range of heavy-duty and passenger vehicle driveline systems. The product meets several key industry and OEM specifications including API GL-4, GL-5 and MT-1 and carries approvals from major manufacturers such as MAN, ZF, Mack and Scania. Physical characteristics include a kinematic viscosity of approximately 169 mm²/s at 40°C and 16.8 mm²/s at 100°C with a viscosity index of approximately 106. The oil has a density of approximately 900 kg/m³ at 15°C, a flash point of approximately 220°C and a pour point of approximately –30°C, supporting reliable lubrication performance across a wide range of operating conditions.
