TEXAS GEARTRA OIL EP GL-4 is an extreme-pressure (EP), multi-grade and multi-purpose gear lubricant for automotive differential and manual transmission, particularly those operating at high-speed, low-torque and lowspeed, high-torque conditions. It is also used in the final drives and other gear cases of truck, cars, buses, farm tractors and earth moving equipment where oil of API GL-4 is required
Blended with highly refined base oils and proven multifunctional gear additives based on Sulphur-phosphorus chemistry, TEXAS GEARTRA EP OIL GL-4 exhibit excellent chemical and thermal stability over a wide range of temperatures.
The extreme-pressure additives in the oils also provide superior protection of gear teeth against spalling. Spalling occurs where flakes of metal breaks away from the surface of a gear tooth after repeated stress.
