Mobiltrans HD 10W
Mobiltrans HD 10W is part of the Mobiltrans HD Series, a range of extra high-performance lubricants engineered for heavy-duty transmissions, gearboxes and drivetrain components. These lubricants are specifically designed to meet or exceed the requirements of the Caterpillar TO-4 specification, ensuring optimal performance in severe off-highway applications. The formulation combines high-quality base oils with an advanced additive system to deliver reliable protection and consistent performance in demanding environments.
One of the key advantages of Mobiltrans HD 10W is its excellent frictional performance. The lubricant is designed with balanced static and dynamic friction characteristics, helping optimise clutch engagement, reduce slippage and extend clutch life. This ensures smooth operation and improved performance in powershift and automatic transmissions.
Mobiltrans HD 10W also provides outstanding wear protection and load-carrying capability. The advanced additive system helps protect gears, bearings and hydraulic components from wear, even under high loads and pressures. This contributes to extended equipment life, reduced downtime and improved productivity.
Another important benefit is its excellent thermal and oxidation stability. The lubricant resists degradation at high operating temperatures, maintaining performance and protecting components over extended service intervals. It also offers effective foam control and delivers smooth performance in wet brake systems, reducing noise and chatter.
Mobiltrans HD 10W is recommended for use in heavy-duty transmissions, final drives, gearboxes and hydraulic systems used in off-highway equipment. It is widely used in industries such as mining, construction, quarrying and agriculture. The lower viscosity grade also provides very good low-temperature pumpability, allowing for faster start-up and improved performance in cold conditions.
Physical characteristics include SAE 10W viscosity grade with kinematic viscosity of approximately 42 mm²/s at 40°C and 6.3 mm²/s at 100°C. Mobiltrans HD 10W has density of approximately 0.888 kg/L at 15°C, flash point of approximately 202°C and pour point of approximately −33°C. The lubricant delivers reliable performance, strong protection and efficient operation in demanding heavy-duty applications.
