The lubricating oil composition for a continuously variable transmission of the present invention has (A) sulfur content of 0.03 mass% or less, mineral oil or PAO having a kinematic viscosity at 100 ° C of 1.5 mm 2 / s or more and 3 mm 2 / s or less, and (B) sulfur content Mineral oil or PAO which is 0.03 mass% or less and whose kinematic viscosity in 100 degreeC is 5.5 mm < 2> / s or more and 8 mm < 2> / s or less, and (C) Kinematic viscosity in 100 degreeC is 30 mm < 2> / s or more and 400 mm < 2> / s It is made by mix | blending the following PAO and (D) polymethacrylate whose mass mean molecular weights are 10000 or more and 40000 or less in specific compounding quantity, The total amount of the said (C) component and the said (D) component is 19 mass% or more, and is 100 degreeC. The kinematic viscosity at is 5.5 mm 2 / s or more and 6.5 mm 2 / s or less, while the kinematic viscosity at -20 ° C is 680 mm 2 / s or less. |
