    摘要： A lubricating oil composition which comprises one or more base oils of the group consisting of (A) a mineral oil having a kinematic viscosity of 5-200 m 2 /s at 40°C and an aromatics content of less than 15 percent by weight, (B) an olefinic polymer of 2-16 carbon atoms or its hydride having a number-average molecular weight of 250-4,000, and (C) an alkylbenzene having 1-4 alkyl groups of 1-40 carbon atoms and a total carbon number of said alkyl groups in the range of 6-40, said base oil or oils being blended with a 3-methyl-5-tert-butyl-4-hydroxyphenyl-substituted fatty acid ester in an amount of 0.1-5.0 percent by weight based on total composition. The inventive lubricant composition having such a base oil in combination with the specified fatty acid ester provides a synergistic effect conducive to inhibition or prevention of both oxidation and sludge formation while in use under elevated temperature conditions over extended periods of time.

    摘要： Lubricant base oils are made up essentially of 2 - 15% by weight of a total aromatics content, greater than 60% by weight of isoparaffins and monocyclic naphthenes in total, more than 30% by weight of alkylbenzenes in the total aromatics content and smaller than 4% by weight of tricyclic and tetracyclic aromatics in the total aromatics content. The base oil has great viscosity index, small pour point, high oxidative stability and heat stability and sufficient capability to dissolve sludge.
