Best Gear Oil for Mining Trucks and Heavy-Duty Axles

Mining trucks and heavy-duty axles operate under high torque, shock loading, long duty cycles and dusty conditions. The right gear oil helps protect hypoid gears, bearings, final drives and axle assemblies from wear, scoring and overheating.

What Gear Oil Does in Mining Trucks

Gear oil forms a durable lubricating film between gear teeth and bearings. In mining trucks, this film must withstand high loads, low-speed torque, contamination risk and elevated operating temperatures. A weak oil film may lead to gear pitting, abnormal noise, higher maintenance costs and unplanned downtime.

When to Use GL-5 Gear Oil

API GL-5 gear oil is designed for heavily loaded hypoid gears and axle applications. For mining trucks, dump trucks and construction vehicles, GL-5 gear oils are commonly used where extreme-pressure protection is required.

• GL-5 75W-90 gear oil supports wide-temperature performance and heavy-duty axle protection.
• GL-5 80W-90 gear oil is a common grade for trucks, axles and hypoid gears.
• GL-5 85W-140 gear oil is suitable for severe-duty, high-temperature and high-load axle applications.

How to Select the Right Viscosity Grade

Always follow the equipment OEM recommendation first. For colder environments or mixed operating temperatures, 75W-90 may provide better low-temperature flow. For standard heavy-duty axle service, 80W-90 is widely used. For hot climates, older equipment or very heavy loads, 85W-140 may provide stronger film thickness.
