A grease composition includes a base oil, a thickener, and polymethyl methacrylate particles. The base oil is a poly--olefin. The polymethyl methacrylate particles have an average particle size of 2 m to 7 m. A content of the polymethyl methacrylate particles is 10% by mass to 20% by mass with respect to a total amount of the base oil and the thickener.

A method for preparing a final grease product comprising steps of: (a) mixing a polymeric thickener, which comprises a polymer of propylene, and a lubricating base oil at a temperature above the melting point of the polymeric thickener, wherein the polymeric thickener is present in an amount of 11.5-15.5 wt %, based on the total weight of the mixture so obtained; (b) cooling the mixture as obtained in step (a); (c) subjecting the cooled mixture as obtained in step (b) to a first mechanical treatment, to obtain an intermediate grease; (d) subjecting the intermediate grease as obtained in step (c) to a second mechanical treatment, carried out at a temperature in the range of from 50-90 C., to obtain the final grease product. The method can be applied to manufacturing of a grease.
