摘要：
A lubricant composition comprising 100 parts by weight of an oil having a lubricating oil viscosity and 0.1 to 50 parts by weight of a copolymer of isobutylene and/or propylene with at least one acrylic ester compound, especially a copolymer of isobutylene with at least one acrylic ester. In said composition, the improving effect of the visocity index is excellent and the composition is excellent in shear stability, thermal resistance, aging resistance, and demulsibility.
