A gear oil composition that has a kinematic viscosity at 40° C. in the range of ≥68 to ≤1000 csdt when measured in accordance with ASTM D445 can be made. The gear oil composition is useful as a lubricant in a gear box, especially in a wind turbine gear box.

Gear oil composition

The presently claimed invention relates to a gear oil composition having a kinematic viscosity at 40° C. in the range of ≥68 to ≤1000 cSt when measured in accordance with ASTM D445. The gear oil composition is useful as a lubricant in a gear box, especially in a wind turbine gear box.

The present invention relates to a method of processing a workpiece comprising contacting a tool and a workpiece to effect a change in the shape of the workpiece, and applying a metalworking fluid to a surface area where the tool and the workpiece are in contact, where the metalworking fluid contains a propoxylate of the formula R&#x2014;O&#x2014;(CHO)&#x2014;H, where R is a branched Cto Calkyl and n is from 3 to 30. The invention further relates to the metalworking fluid, and to a use of the propoxylate as additive in metalworking fluids.
