Mobilube LS 85W-90
Mobilube LS 85W-90 is an extra high-performance automotive gear lubricant formulated using select base oils and an advanced additive system specifically for limited-slip differential applications. It is engineered to meet API GL-5 performance requirements, making it suitable for heavy-duty differentials, axles and final drives operating under extreme pressures and shock loading.
One of the key advantages of Mobilube LS 85W-90 is its excellent frictional properties, which are essential for effective limited-slip operation. The formulation helps ensure smooth and controlled engagement of clutch plates within limited-slip differentials, reducing noise, chatter and vibration while maintaining optimal traction.
Mobilube LS 85W-90 also provides strong wear protection and load-carrying capability. The lubricant protects gears and bearings from wear, scuffing and scoring under both low-speed/high-torque and high-speed conditions, helping extend component life and reduce maintenance costs.
Another important benefit is its good thermal and oxidation stability. The formulation resists degradation at high temperatures, minimising deposit formation and ensuring clean and efficient operation over extended service intervals. It also offers excellent protection against rust, corrosion and staining, safeguarding metal components in demanding environments.
Mobilube LS 85W-90 delivers effective low-temperature performance, allowing for reliable lubrication during cold start-up and reducing wear in varying operating conditions. It also offers good resistance to foaming, ensuring consistent lubrication film strength and performance.
Mobilube LS 85W-90 is recommended for limited-slip differentials, axles and final drives in passenger cars, trucks, buses and off-highway equipment used in construction, quarrying and agriculture. It is also suitable for other industrial and automotive applications involving hypoid gears operating under severe conditions.
Physical characteristics include SAE 85W-90 viscosity grade with kinematic viscosity of approximately 153 mm²/s at 40°C and 15.3 mm²/s at 100°C. Mobilube LS 85W-90 has density of approximately 0.90 kg/L at 15°C, flash point of approximately 216°C and pour point of approximately −36°C. The lubricant delivers reliable limited-slip performance, strong protection and long service life in demanding drivetrain applications.
