Embodiment

[0053] Hereinafter, the present invention will be specifically described through examples.

[0054] As the mineral oil base oil, the kinematic viscosity at 100°C obtained by hydrodewaxing the product oil obtained by the hydrocracking of heavy oil is 4.3 mm. 2 / s base oil.

[0055] As a dicarboxylic acid diester having a molecular weight of 400 to 450 represented by the general formula (1) (hereinafter referred to as the diester of the present invention), the kinematic viscosity at 100°C is 3.2mm 2 / s, dioctyl sebacate with a molecular weight of 426.

[0056] In addition, as a comparative diester that does not satisfy the diester of the present invention, a kinematic viscosity at 100°C of 3.6 mm was used. 2 / s, diisodecyl adipate with a molecular weight of 426, the kinematic viscosity at 100°C is 2.3mm 2 / s, dioctyl adipate with a molecular weight of 370 and a kinematic viscosity of 3.4mm at 100°C 2 / s of trimethylolpropane (TMP) enanthate.

[0057] As additives, the follo...

Abstract

The fuel-saving engine oil composition comprises a mineral oil-based and / or synthetic oil-based base oil for a lubricating oil containing not less than 30 mass% dicarboxylic acid diester with a molecular weight of 400-450 represented by formula (1) (wherein R<SP>1< / SP>and R<SP>2< / SP>each independently denotes a 1-16C hydrocarbon group; and R<SP>3< / SP>denotes a 6-10C divalent hydrocarbon group) and an organomolybdenum compound in an amount of not less than 0.03 mass% in terms of the amount of molybdenum (Mo).

Description

[0001] This application is a divisional application of the Chinese invention patent application with the application number 200910008396.3 and the name "fuel consumption-saving engine oil composition" filed on February 27, 2009. technical field [0002] The present invention relates to a fuel-efficient engine oil comprising a lubricating base oil containing a specific diester and an organic molybdenum compound, and relates to a fuel-efficient engine oil having good environmental performance due to low evaporation and good low-temperature viscosity characteristics. Background technique [0003] In recent years, in order to prevent global warming, improve the fuel consumption characteristics of automobiles and suppress CO 2 The calls for emissions are high. In order to improve the fuel consumption characteristics of automobiles, it is important to increase the efficiency of the engine, and the technologies of lean burn and direct injection are adopted in gasoline engines. On ...
