Truck gear oil, also known as axle oil, transmission oil, gear lubricant, or differential oil, is a specialized lubricant designed to protect and lubricate gears and transmissions in trucks. These components are crucial for transferring power from the engine to other parts by adjusting speed and torque. Using the correct gear oil is essential for ensuring optimal performance and extending the lifespan of a truck’s drivetrain.

The Role of Truck Gear Oil
Truck gear oil performs several vital functions, including:
- Lubrication: Reduces friction and wear between gears, enabling smooth and efficient drivetrain operation.
- Cooling: Absorbs and dissipates heat generated during operation, preventing overheating and component damage.
- Cleaning: Removes dirt, metal particles, and other contaminants, keeping the drivetrain clean and functioning reliably.
- Corrosion Prevention: Protects metal components from corrosion caused by environmental factors and chemicals.
- Power Transmission: In some hydraulic systems, gear oil also plays a role in power transmission.
Types of Truck Gear Oil
Truck gear oils are classified based on their viscosity and API quality rating.
Viscosity: Common viscosity grades include SAE 90, SAE 140, SAE 80W90, and SAE 85W140. The appropriate viscosity depends on operating conditions and manufacturer recommendations.
API Quality Rating: The American Petroleum Institute (API) categorizes gear oils into seven levels: GL-1 to GL-6 and MT-1. Currently, GL-4, GL-5, and MT-1 are the most prevalent. Each level meets different technical requirements for load-bearing capacity, wear resistance, and corrosion protection. GL-4 is typically used for manual transmissions and front axles, while GL-5 is for heavy-duty rear axles.
Choosing the Right Truck Gear Oil
Selecting the correct gear oil for your truck is crucial for ensuring the performance and longevity of the drivetrain. Always adhere to the manufacturer’s recommendations for viscosity and API quality rating. Using substandard gear oil can lead to rapid wear, transmission damage, and costly repairs.
