Summary:To provide a friction-reducing agent containing no sulfur nor phosphorus and being excellent in friction-reducing properties, and a lubricating oil composition using it.An alkanolamine represented by the following formula (1) is used as a friction-reducing agent:wherein A1and A2are each independently a hydroxy group or a hydrogen atom, provided that A1and A2are not hydrogen atoms at the same time, R1is a hydrocarbon group having at most 30 carbon atoms, R2to R6are each independently a hydrogen atom or a hydrocarbon group having at most 30 carbon atoms, and m and n are each independently an integer of from 0 to 10.
