Document Type and Number:
WIPO Patent Application WO/2018/139403
Kind Code:
A1
Abstract:
The problem to be solved by the present invention is to provide a fuel-saving-type engine oil composition, in which a low-viscosity engine oil is not constrained by a matter that the temperature is high or low, the load is low or high or the like and a good friction-reducing effect can be exhibited. The present invention is an engine oil composition characterized by containing: an engine oil which has a low-temperature viscosity of 0 to 10 in terms of an SAE viscosity grade and a high-temperature viscosity of 4 to 20 in terms of an SAE viscosity grade; and a molybdenum compound (A) represented by general formula (1) (wherein R1 to R4 independently represent a hydrocarbon group having 4 to 18 carbon atoms, wherein all of R1 to R4 do not represent the same group, and R3 and R4 do not represent the same group when R1 and R2 represent the same group; and X1 to X4 independently represent a sulfur atom or an oxygen atom).
