Abstract:
Provided is an additive for lubricating oils which enhances frictional characteristics of slide parts in internal combustion engines and driving system transmission engines and which exhibit an excellent fuel consumption reducing effect. The above additive for lubricating oils comprises a heterocyclic compound having a heterocyclic skeleton originating in a compound selected from pyridines, pyrroles, pyrimidines, pyrazoles, pyridazines, indazoles, pyrazines, triazines, triazoles, tetrazoles, oxazoles, oxadiazoles, thiazoles, thiadiazoles, furans, dioxanes, pyrans and thiophenes. A lubricating oil composition containing the above additive for lubricating oils is effectively used for various low friction slide members, antifriction bearings and slide bearings.
