Abstract (en)
[origin: EP1191090A2] A lubricant composition suitable for use as an automotive or industrial gear lubricant comprising: (A) from about 40 to about 70 wt. %, based on the total weight of the lubricant composition, of a mineral oil; (B) from about 2 to about 20 wt. %, based on the total weight of the lubricant composition, of at least one selected from vinyl aromatic-diene copolymers, olefin copolymers and mixtures thereof; (C) from about 2 to about 20 wt. %, based on the total weight of the lubricant composition, of at least one polyalphaolefin having a kinematic viscosity of at least 40 cSt at 100 DEG C; and (D) from about 3 to about 20 wt. %, based on the total weight of the lubricant composition, of a gear additive package; wherein the lubricant composition has a Viscosity Index of greater than 140.
