The invention provides a cold-proof grease composition for reducing noise. In certain embodiments, the invention provides a grease composition having an improved noise-reduction effect without sacrificing lubricant adhesiveness at high and low temperatures. In one embodiment, the grease composition comprises a synthetic hydrocarbon oil as a base oil, a lithium-based thickener, and a poly(methyl acrylate) (PMA)-based copolymer. |
