Abstract

Lubricating oil compositions and viscosity index (VI) improver concentrates containing combinations of first polymers that arc amorphous ethylene α-olefin copolymers; and second polymers that are star polymers, the arms of which are derived from diene, and optionally vinyl aromatic hydrocarbon monomer, wherein the star polymers have a Shear Stability Index (SSI) of from about 1% to about 35% (30 cycle).
