FRICTION MODIFIER COMPRISING METAL SALICYLATE AND LUBRICATING OIL COMPOSITION CONTAINING THE SAME

摘要

Lubricating oil compositions containing novel chain-hydrocarbon-group-substituted metal salicylates having friction reducing ability are provide d. A friction modifier comprising a chain-hydrocarbon-group- substituted metal salicylate substituted by at least one chain hydrocarbon group, wherein the chain hydrocarbon group has an alkyl chain linearity of 20% or higher as determined by a carbon nuclear magnetic resonance measurement (13C-NMR measurement); and a lubricating oil composition with the metal salicylate added therein are disclosed.
