Lubricating oil composition

Abstract

To provide a lubricant composition capable of having good balance among a low traction coefficient, high low temperature fluidity and a high oil consumption reduction performance.SOLUTION: There is provided a lubricant composition which comprises the following base oils (A) and (B): (A) a poly-α-olefin-based base oil which is a 1-tetradecene polymer and (B) at least one kind of a base oil selected from a group consisting of a group V base oil in API base oil classification and a poly-α-olefin-based base oil other than the base oil (A), wherein the base oil (A) contains a component (A1) which is a 1-tetradecene dimer and a component (A2) which is a 1-tetradecene trimer, a mass ratio ([component (A1)] / [component (A2)]) of the component (A1) to the component (A2) contained in the base oil A is 3 to 10, a content of the base oil (A) is 40 mass% or more and 85 mass% or less based on a total amount of the lubricant oil, a content of the base oil (B) is 15 mass% or more and 60 mass% or less based on the total amount of the lubricant oil and a total amount of the base oil (A) and the base oil (B) is 80 mass% or more based on the total amount of the lubricant oil.SELECTED DRAWING: None
