摘要: A lubricating oil composition that is hard to increase in viscosity in the low temperature range and is easy to increase in viscosity in the high temperature range. The lubricating oil composition contains a base oil and a viscosity index improver. The base oil contains a mineral oil and an oxygen-containing synthetic oil. The viscosity index improver contains a comb-shaped polymer. The lubricating oil composition has a kinematic viscosity of 100° C. of 9.3 mm2/s or less, a viscosity index of 280 or more, and a content Y (% by mass) of the oxygen-containing synthetic oil based on the total amount of the lubricating oil composition satisfying the following expression (1): α≤Y

摘要: A polyester is useful as a high viscosity base fluid. A method for its preparation involves epoxidizing an alpha-olefin, reacting the alpha-epoxide or diol with a saturated linear aliphatic dicarboxylic acid, and isolating the polyester. Lubricant compositions can contain such polyesters and the compositions are useful as automatic transmission fluids, manual transmission fluids, continuously variable transmission fluids, gear oil formulations, industrial gear oil formulations, axle fluid formulations, dual clutch transmission fluids, dedicated hybrid transmission fluids, or as hydraulic oils.
