Abstract:
Provided are a lubricating oil composition containing a mineral oil (1) having a kinematic viscosity at 100° C. of 2 mm 2 /s or more and less than 2.5 mm 2 /s, and a polymethacrylate (2) having a 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 7):
The lubricating oil composition according to  claim 1 , wherein the rate of change in kinematic viscosity at 40\u00b0 C. of the composition, as calculated according to the following method, is 5% or less:\n Method for calculating rate of change in kinematic viscosity at 40\u00b0 C.; \n with respect to an ultrasonically-treated composition obtained by irradiating a lubricating oil composition with ultrasonic waves for 60 minutes according to JASO M347-95 and an untreated lubricating oil composition, their kinematic viscosity at 40\u00b0 C. (v 1 , v 0 ) is measured according to JIS K2283:2000, and the rate of reduction ((v 0 \u2212v 1 )/v 0 \u00d7100) is referred to as the rate of change in kinematic viscosity at 40\u00b0 C.
