Without these additives, even a high-viscosity oil would fail under stress. The Science Behind Gear Lubrication Gear oils are fundamentally different from engine oils, and this distinction is vital to understand their function.

Furthermore, it is a common choice for medium-duty trucks and agricultural equipment, where components are subjected to frequent stops, starts, and heavy torque. This particular viscosity grade is often recommended for applications that see a wide range of temperatures and loads, making it a staple for both classic vehicles and modern trucks.
As the machinery heats up under load, the oil thickens to an SAE 90 consistency, maintaining a durable film strength to prevent metal-to-metal contact. These designs require a lubricant that can withstand the sliding and shearing forces inherent in their gear mesh.

The base stock is typically more viscous and less volatile, ensuring the lubricant stays in place between the gears rather than being thrown off by centrifugal force. Engine oils are designed to lubricate moving parts in a low-viscosity environment to reduce friction and manage heat.
