Shell Spirax S5 ATE 75W-90
Shell Spirax S5 ATE 75W-90 is a premium performance synthetic technology gear oil developed to meet the demanding requirements of modern high-performance passenger car driveline systems. Formulated with carefully selected synthetic base oils and advanced additive technology, the lubricant provides outstanding wear protection, excellent synchromesh compatibility and reliable lubrication performance in heavily loaded drivetrain applications. The oil is specifically designed for use in transaxle transmissions where both the gearbox and hypoid axle share the same lubricant.
One of the key advantages of Shell Spirax S5 ATE 75W-90 is its outstanding gear protection and synchromesh performance. Transaxle transmission designs place significant demands on lubricants because they require both excellent extreme-pressure gear protection and smooth synchroniser operation. The advanced additive system combined with high-quality base oils provides a durable protective film between gear surfaces while maintaining stable friction characteristics for synchronisers. This helps ensure smooth gear engagement while protecting gears from wear, pitting and surface damage under heavy loads.
Shell Spirax S5 ATE 75W-90 also contributes to longer equipment life. The high shear stability of the formulation helps maintain consistent viscosity even under severe mechanical stress, ensuring reliable lubrication performance throughout the oil service interval. The strong extreme-pressure performance protects heavily loaded gear teeth and helps prevent premature component failure. In addition, excellent oxidation and thermal stability help prevent deposit formation that could damage seals or reduce drivetrain reliability.
Another important benefit of Shell Spirax S5 ATE 75W-90 is its ability to improve drivetrain efficiency. The synthetic formulation reduces internal friction within gear systems, helping improve overall mechanical efficiency and performance. This can contribute to smoother vehicle operation and improved energy efficiency while maintaining excellent protection for drivetrain components across a wide range of operating temperatures.
Shell Spirax S5 ATE 75W-90 is also designed with environmental considerations in mind. The formulation offers excellent seal compatibility to reduce the risk of leaks, while the low-chlorine additive system and extended oil drain capability help reduce environmental impact and lubricant consumption over time.
The lubricant is recommended for heavily loaded automotive transmissions including transaxle designs where the gearbox and hypoid axle are lubricated by a common oil. It is particularly suited for high-performance passenger car drivetrain systems and is recognised by leading sports car manufacturers. The product meets API GL-4, GL-5 and MT-1 service classifications and carries approvals including MB 236.26. It is also recognised by manufacturers such as Ferrari and Getrag for use in high-performance applications. Physical characteristics include a kinematic viscosity of approximately 81 mm²/s at 40°C and 14.9 mm²/s at 100°C with a viscosity index of approximately 194. The oil has a density of approximately 879 kg/m³ at 15°C, a flash point of approximately 205°C and a pour point of approximately –45°C, supporting reliable lubrication performance across a wide range of operating conditions.
