75w 140 gear oil is a type of lubricant specifically designed for heavy-duty applications, such as large trucks, towing, hauling, and industrial machinery. It falls under the “high-performance” or “heavy-duty” gear oils formulated to withstand extreme pressures and temperatures. The numbers in the name refer to the oil’s viscosity grade.

The first number, 75w, indicates its cold-start rating or how well it flows at low temperatures. The “w” stands for winter, and the lower the number before it, the better it performs in cold weather conditions. In this case, 75w means it can flow like a 75-grade oil in winter.

The second number, 140, represents the oil’s viscosity at high temperatures. Higher numbers indicate thicker oils that better protect against extreme heat and pressure.
