Mobiltrans HD 30
Mobiltrans HD 30 is part of the Mobiltrans HD Series, a range of extra high-performance lubricants engineered for heavy-duty transmissions, gearboxes and drivetrain systems. These lubricants are designed to meet or exceed 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 operating environments.
One of the key advantages of Mobiltrans HD 30 is its optimised frictional performance. The lubricant is formulated with balanced static and dynamic friction characteristics, ensuring smooth clutch engagement and effective slippage control. This helps extend clutch life and improves performance in powershift, manual and automatic transmissions.
Mobiltrans HD 30 also provides excellent wear protection and load-carrying capability. The advanced additive system protects gears, bearings and drivetrain components from wear under high load and pressure conditions. This contributes to longer equipment life, reduced maintenance costs and improved productivity.
Another important benefit is its excellent thermal and oxidation stability. The lubricant resists breakdown at elevated temperatures, maintaining consistent performance and protecting system components over extended service intervals. It also offers effective foam control and excellent wet brake performance, helping reduce brake chatter and noise.
Mobiltrans HD 30 is recommended for 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 product is also suitable for applications requiring Allison C-4 performance levels and is compatible with modern clutch materials and elastomers.
Physical characteristics include SAE 30 viscosity grade with kinematic viscosity of approximately 100 mm²/s at 40°C and 11.2 mm²/s at 100°C. Mobiltrans HD 30 has density of approximately 0.893 kg/L at 15°C, flash point of approximately 224°C and pour point of approximately −18°C. The lubricant delivers reliable performance, strong wear protection and long service life in demanding heavy-duty applications.
