Mobilube HD 75W-90
Mobilube HD 75W-90 is a high-performance automotive gear lubricant formulated to meet the requirements of API GL-5. It is engineered using high-quality base oils combined with a highly shear-stable viscosity index improver, ensuring consistent performance under demanding operating conditions. This formulation is designed to provide reliable lubrication for heavy-duty axles, final drives and drivetrain components exposed to high loads and severe service environments.
One of the key advantages of Mobilube HD 75W-90 is its excellent wear protection and load-carrying capability. The lubricant helps protect gears and bearings from wear, scuffing and scoring under both low-speed/high-torque and high-speed conditions. This contributes to extended component life and reduced maintenance costs.
Mobilube HD 75W-90 also provides strong thermal and oxidation stability. The formulation resists breakdown at elevated temperatures, helping minimise deposit formation and maintain clean internal components. This ensures consistent performance and supports extended service intervals in demanding applications.
Another important benefit is its excellent protection against rust and corrosion. The lubricant helps safeguard metal surfaces, including steel and copper alloys, ensuring long-term durability and reliable operation in harsh environments. It is also compatible with typical seals and gaskets, helping reduce leakage and contamination.
Mobilube HD 75W-90 offers effective low-temperature performance, providing good fluidity and improved startability in cold conditions. This helps reduce wear during start-up and ensures reliable lubrication across a wide temperature range.
Mobilube HD 75W-90 is recommended for heavy-duty axles and final drives in passenger cars, trucks and commercial vehicles, as well as off-highway equipment used in construction, mining, quarrying and agriculture. It is suitable for applications involving hypoid gears operating under severe conditions, including shock loading and high torque.
Physical characteristics include SAE 75W-90 viscosity grade with kinematic viscosity of approximately 101 mm²/s at 40°C and 16 mm²/s at 100°C. Mobilube HD 75W-90 has density of approximately 0.88 kg/L at 15°C, flash point of approximately 200°C and pour point of approximately −45°C. The lubricant delivers reliable performance, strong protection and long service life in demanding drivetrain applications.
