A lubricant composition including a first fluid having a viscosity from 150 cSt to 2000 cSt at 40° C. (ASTM D-445) and a traction coefficient from 0.01 to 0.025 (MTM TC Method), and a second fluid having a viscosity from 1 cSt to 30 cSt at 40° C. (ASTM D-445) and a traction coefficient from 0.008 to 0.015 (MTM TC Method). The second fluid is miscible with the first fluid. The traction coefficient of the lubricant composition is lower than the traction coefficient of the first fluid and the traction coefficient of second fluid, as determined by the MTM TC Method. Provided is also a method of reducing the traction coefficient of a lubricant composition.
A method of reducing the traction coefficient of a lubricant composition, said method comprising blending a first fluid having a viscosity from 150 cSt to 2000 cSt at 40° C. (ASTM D-445) and a traction coefficient from 0.01 to 0.025 (MTM TC Method), with a second fluid having a viscosity from 1 cSt to 30 cSt at 40° C. (ASTM D-445) and a traction coefficient from 0.008 to 0.015 (MTM TC Method);
