LUBRICANT COMPOSITION FOR CONTINUOUSLY VARIABLE TRANSMISSION |
摘要 |
A lubricating oil composition for a continuously variable transmission contains at a specific content: (A) a mineral oil or PAO having a sulfur content of 0.03 mass% or less and a kinematic viscosity at 100 degrees C from 1.5 mm 2 /s to 3 mm 2 /s; (B) a mineral oil or PAO having a sulfur content of 0.03 mass% or less and a kinematic viscosity at 100 degrees C from 5.5 mm 2 /s to 8 mm 2 /s; (C) PAO having a kinematic viscosity at 100 degrees C from 30 mm 2 /s to 400 mm 2 /s; and (D) a polymethacrylate having a mass average molecular weight of 10000 to 40000, in which the total content of the components (C) and (D) is 19 mass% or more and the lubricating oil composition has a kinematic viscosity at 100 degrees C from 5.5 mm 2 /s to 6.5mm 2 /s and a kinematic viscosity at -20 degrees C of 680 mm 2 /s or less. |
