Document Type and Number:
Japanese Patent JP2017197608
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lubricating oil composition for an agricultural machine which holds adequate lubricity and furthermore is excellent in low temperature startability and low temperature storage stability, and does not bring about haze.SOLUTION: The lubricating oil composition for an agricultural machine is provided which contains lubricating oil base oil (A) having a kinetic viscosity at 100°C of 10-13 mm/s, a viscosity index of 90 or more and a flow point of -30°C or lower, lubricating oil base oil (B) having a kinetic viscosity at 100°C of 5-9 mm/s, a viscosity index of 120 or more and a flow point of -10°C or lower, and lubricating oil base oil (C) having a kinetic viscosity at 100°C of 2-4 mm/s, a viscosity index of 90 or more and a flow point of -35°C or lower, and in which when the total amount of the base oil content in the lubricating oil composition for agricultural machine is 100 vol.%, a volume ratio of the lubricating oil base oil (A) to the total amount of the base oil is 30 vol.% or more, the total of a volume ratio of the lubricating oil base oil (B) and a volume ratio of the lubricating oil base oil (C) is 30 vol.% or more, and kinetic viscosity at 100°C of the base oil content in the lubricating oil composition is 5.0-8.5 mm/s.SELECTED DRAWING: None
