Abstract: The present disclosure provides a lubricating composition with improved high-pressure pumpability and/or reduced viscosity at high pressures, as well as method of making and using the same. The lubricating composition includes a white oil and a polymeric thickener present in an amount equal to or less than about 40 wt % of the lubricating composition. The white oil has a kinematic viscosity of at least one of: about 80 mm2/sec to about 120 mm2/sec at 40° C. and/or about 9.5 mm2/sec to about 14 mm2/sec at 100° C.

Abstract: The present disclosure relates generally to lubricating compositions and methods of making and using the same. Specifically, the present disclosure relates to lubricating compositions and method of making and using the same for modifying friction at a metal-elastomer contact, and therefore improving at least one of elastomer lifetime, reducing elastomer wear, reducing metal wear, reducing energy consumption or a combination thereof. More specifically, one aspect of the present disclosure relates to lubricating compositions including at least two base oils with a viscosity difference between the first and second base oils; another aspect of the present disclosure relates to lubricating compositions comprising an additive that can modify friction at a metal-elastomer contact.
