Document Type and Number:
WIPO Patent Application WO/2022/209487
Kind Code:
A1
Abstract:
The present invention pertains to a lubricating oil composition comprising a mineral base oil (A), a polymer (B) having a weight-average molecular weight (Mw) of 100-15,000, and a molybdenum-based friction regulator (M), and having a kinematic viscosity of at most 35.0 mm2/s at 40ºC. The present invention thus provides a lubricating oil composition having an excellent friction coefficient-reducing effect even when a member having a small surface roughness is lubricated in a low oil temperature range.
