    Abstract: The present invention provides an engine oil composition including 70 to 95 percent by weight of a base oil and 0.01 to 15 percent by weight of a dispersant comb polymer, based on the overall weight of the engine oil composition. The dispersant comb polymer consists of 13.7% by weight of a macromonomer, which is an ester of methacrylic acid and a hydroxylated hydrogenated polybutadiene with Mn of 4750 g/mol; 51.5% by weight of n-butyl methacrylate; 17.3% by weight of LMA; 11.2% by weight of styrene; 0.2% by weight of methyl methacrylate; and 6.10% by weight of N,N-dimethylaminoethyl methacrylate. The modified dispersant inhibitor package contains 30 wt % or less of succinimide type dispersant based on the overall weight of the modified dispersant inhibitor additive package, and the engine oil composition has an SAE viscosity grade of 0W-X, wherein X is 30 or less.
