Mobilube S 80W-90
Mobilube S 80W-90 is an extra high-performance drivetrain lubricant engineered to provide excellent lubrication for modern and older manual transmission systems used in on-highway vehicles and commercial equipment. It is formulated using high-quality base oils and advanced additive technology to deliver balanced performance across wear protection, friction control and thermal stability. The product meets API GL-4/GL-5 performance requirements, making it suitable for a wide range of drivetrain applications.
One of the key advantages of Mobilube S 80W-90 is its outstanding load-carrying and anti-wear performance. The formulation helps protect gears and synchronisers from wear, scuffing and extreme pressure conditions, contributing to extended transmission life and reduced maintenance costs.
Mobilube S 80W-90 also delivers excellent shifting performance. Its optimised frictional properties help ensure smooth and precise gear engagement, improving driver comfort and overall transmission efficiency. This is particularly important in modern drivetrain systems where synchroniser durability and performance are critical.
Another important benefit is its strong thermal and oxidation stability. The lubricant resists degradation at elevated temperatures, helping to minimise deposit formation and maintain clean system components. This supports extended service intervals and reliable long-term performance.
Mobilube S 80W-90 also provides excellent protection against rust and corrosion, including protection for copper alloys. It maintains viscosity and film strength under severe operating conditions due to its excellent shear stability, ensuring consistent lubrication performance over time.
Mobilube S 80W-90 offers good low-temperature fluidity, allowing for easier start-up and smoother shifting in cold conditions. This helps reduce wear during start-up and ensures reliable performance across a wide range of operating temperatures.
Mobilube S 80W-90 is recommended for cars, light and heavy-duty trucks, buses and vans, as well as heavy-duty drivetrain systems requiring API GL-4 or GL-5 performance. It is suitable for a wide variety of automotive and commercial applications, helping simplify lubricant selection and improve operational efficiency.
Physical characteristics include SAE 80W-90 viscosity grade with kinematic viscosity of approximately 144 mm²/s at 40°C and 15 mm²/s at 100°C. Mobilube S 80W-90 has density of approximately 0.90 kg/L, flash point of approximately 210°C and pour point of approximately −30°C. The lubricant delivers reliable protection, smooth operation and long service life across a wide range of drivetrain applications.
