Definitions

  • Lubricating oil compositions are used in a wide variety of applications such as automobiles and machines. In recent years, lowering the viscosity of automotive lubricating oil compositions has been demanded from the viewpoint of fuel efficiency. However, lowering the viscosity of the lubricating oil composition affects the oil film forming ability. In particular, in the field of automotive gear oils, and more particularly in lubricating oils used for differential gears, reducing the viscosity of the lubricating oil causes problems such as the occurrence of wear on bearings and the occurrence of scoring on gear tooth surfaces. Therefore, it was difficult to cope with the low viscosity. Therefore, it is hoped to develop a gear oil composition for automobiles, particularly a differential gear oil composition, which can suppress wear on bearings and the like under conditions where oil film formation is difficult at high temperatures even with low viscosity oil. It is rare.
