Shell Spirax S2 G 80W-90
Shell Spirax S2 G 80W-90 is a high-quality automotive gear lubricant developed to provide reliable performance in manual transmissions and moderate duty gear systems. Formulated with high-quality base oils and multifunctional additives, the lubricant delivers dependable protection against wear, corrosion and oxidation while maintaining stable lubrication performance across a wide range of operating conditions. The oil is designed to support the lubrication requirements of manual gearboxes and other gear systems operating under mild extreme-pressure conditions.
One of the key advantages of Shell Spirax S2 G 80W-90 is its effective anti-wear and gear protection capability. The lubricant incorporates specially selected additives that help reduce metal-to-metal contact between gear surfaces. This helps protect gears and bearings from scuffing and wear during operation, supporting long component life and maintaining reliable transmission performance even under varying load conditions.
Shell Spirax S2 G 80W-90 also offers excellent protection against rust and corrosion. Automotive gear systems may be exposed to moisture or contaminants during operation, which can increase the risk of corrosion on internal components. The lubricant’s additive system helps prevent rust formation on metal surfaces, protecting gearbox components and ensuring reliable long-term performance of drivetrain systems.
Another important benefit of Shell Spirax S2 G 80W-90 is its strong oxidation stability. Gear oils operating under high temperatures and mechanical stress can degrade over time, which may lead to the formation of deposits and reduced lubrication performance. The formulation helps resist oxidation and maintain oil stability, helping ensure consistent lubrication and reliable performance throughout the oil service interval.
Shell Spirax S2 G 80W-90 is recommended for use in manual gearboxes in motorcycles, passenger cars and commercial vehicles operating in both on-road and off-road conditions. The lubricant is particularly suitable for gearboxes fitted with synchromesh where smooth gear engagement and stable lubrication are required. It may also be used in certain rear axle applications operating under moderate duty conditions such as light-duty commercial vehicles and passenger cars. However, it is not recommended for heavily loaded hypoid axles where higher extreme-pressure performance is required.
The lubricant meets the API GL-4 service classification for automotive gear oils. 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 900 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.
