A grease composition is disclosed. The grease composition comprises: 100 parts by mass of (A) an aryl group-containing polyorganosiloxane; 1 to 50 parts by mass of (B) an acrylic block copolymer; and (C) solid particles. Component (B) has a weight average molecular weight of from 10,000 to 1,000,000 and a molecular weight distribution [ratio (Mw/Mn) of weight average molecular weight (Mw) to number average molecular weight (Mn)] of 1.5 or less. Component (B) is present in an amount of from 1 to 40 mass % of the overall grease composition. The grease composition has excellent damping characteristics, hardly any oil separation (even at high temperatures), excellent lubricating performance, and an ability to reduce noise generated by a mechanical device when applied to a noise-generating site of the mechanical device. Sliding members, etc., to which this grease composition has been applied, are also disclosed.

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 mm.sup.2/sec to about 120 mm.sup.2/sec at 40 C. and/or about 9.5 mm.sup.2/sec to about 14 mm.sup.2/sec at 100 C.
