Quality control of a functional fluid

The present invention relates to lubricating greases comprising at least one thickening agent and at least one lubricating oil, wherein the lubricating grease contains at least one polymeric structure improver that can be obtained by polymerization of monomer compositions, which are composed of in which R represents hydrogen or methyl, Rdenotes a straight-chain or branched alkyl moiety having 1 to 5 carbon atoms, in which R represents hydrogen or methyl, Rdenotes a straight-chain or branched alkyl moiety having 6 to 30 carbon atoms,

Lubricating grease with high water resistance

A method for improving the low temperature fluidity of lubricating oil compositions based on addition to lubricating oils of a mixture of selected high molecular weight and low molecular weight alkyl (meth)acrylate copolymers is disclosed. Combinations of low molecular weight alkyl (meth)acrylate polymers containing zero to 25 weight percent (C -C )alkyl (meth)acrylate with high molecular weight alkyl (meth)acrylate polymers containing 25 to 70 weight percent (C -C )alkyl (meth)acrylate are especially effective at satisfying different aspects of low temperature fluidity properties simultaneously for a broad range of base oils.
