Provided is a lubricant composition including 30mass% or more, based on the total quantity of the lubricant composition, of a mineral oil (A) that includes a bright stock (A1), and further including a synthetic oil (B) and a phosphoric acid ester (C), wherein the content of the synthetic oil (B) is less than 70mass% based on the total quantity of the lubricant composition, the content of the phosphoric acid ester (C) in terms of phosphorus atoms is 0.050-0.200mass% based on the total quantity of the lubricant composition, and the viscosity index is 150 or greater, whereby the lubricant composition has a low temperature dependence and good lubrication properties even when a mineral oil including a bright stock is used. |
