Product Description

The **OS Giken OS011-KA16 80W-250 gear oil** is a high-performance lubricant engineered for demanding drivetrain applications requiring a heavy-viscosity gear oil. With an 80W-250 rating, this oil delivers a robust lubricating film capable of protecting gears under high torque, elevated temperature, and continuous load conditions. Its formulation is tailored for both motorsport and heavy-duty street service where an 80W-250 GL-5 oil is specified by the component manufacturer. 

Unlike typical motor oils, this gear oil provides a thicker base oil with additives that help resist thermal breakdown, protect against metal-to-metal contact, and maintain consistent performance across a wide range of operating conditions. Because it is universally applicable, it should only be used in gearboxes, differentials, or transmissions that explicitly call for 80W-250 viscosity and GL-5 performance in their specifications. Always consult the OEM service manual or component instructions to verify compatibility before use.
