Abstract: This invention relates to a lubricating composition comprising at least about 30% by weight at least one mineral oil, having a kinematic viscosity of less than about 8 cSt at 100 DEG C, (A) from about 15% to about 40% by weight of at least one polymer, and (B) up to about 30% by weight of at least one fluidizing agent, provided that when the fluidizing agent is a poly alpha -olefin having a kinematic viscosity from about 2 to about 30 cSt at 100 DEG C, then the poly alpha -olefin is present in an amount up to about 12% by weight, wherein the lubricating composition has a shear loss of less than about 15% in the 20 hour taper bearing shear test. The invention also relates to concentrates used in preparing lubricating compositions. The present combination of components provides good low and high temperature properties especially when used in combination with one or more mineral oils. In one aspect, the compositions provide improved oxidation resistance.

Abstract: This invention relates to a lubricating composition comprising at least about 30% by weight of at least one mineral oil, having a kinematic viscosity of less than about 8 cSt at 100 DEG C, (A) from about 5% to about 30% by weight at least one polymer having a Mw less than about 10,000, and (B) from about 2% to about 12% by weight of a polymer having a Mw greater than about 15,000, wherein the lubricating composition has a shear loss of less than about 15% in the 20 hour taper bearing shear test. The invention also relates to concentrates used in preparing shear stable lubricating compositions. The present combination of components provides good low and high temperature properties to mineral oils, even at high treat levels. These lubricants have good shear stability and in one aspect have improved oxidation resistance.
