Abstract:
Provided are a lubricating oil composition containing a synthetic oil (1) having a kinematic viscosity at 100° C. of 2.5 mm 2 /s or less, and a polymethacrylate (2) having a monovalent functional group containing an oxygen atom in the molecule while having a specific structural unit, which satisfies both high viscosity index and high shear stability, and a lubrication method and a transmission using the lubricating oil composition.

Claim (Index 1):
A lubricating oil composition, comprising:\n a synthetic oil (1) having a kinematic viscosity at 100\u00b0 C. of 2.5 mm 2 /s or less; and a polymethacrylate (2) having a monovalent functional group comprising an oxygen atom in the molecule, which has a structural unit represented by formula (I): wherein R 1  represents a divalent aliphatic hydrocarbon group having 24 to 40 carbon atoms; and X 1  represents a monovalent functional group containing an oxygen atom.
