(57) Abstract: A method for improving the low temperature fluidity of lubricating oil compositions based on the addition of a mixture of selected high and low molecular weight alkyl (meth) acrylate copolymers to a lubricating oil is described. (C 16 -C 24) alkyl height containing (meth) and a low molecular weight alkyl (meth) acrylate containing 0-25 wt% acrylate, 25 to 75 wt% (C 16 -C 24) alkyl (meth) acrylate The combination with a molecular weight alkyl (meth) acrylate is particularly effective in that it satisfies different viewpoints of low-temperature fluidity characteristics over a wide range of base oils. |
