Abstract

Lubricant formulations containing a combination, which has a synergistic action in respect of metal deactivation, composed of 1-[di-(2-ethylhexyl)-aminomethyl]-benztriazole which is methylated in the benzene ring in the 4-position and/or 5-position, and an antioxidant selected from a small group of antioxidants. Further additives can be added to these lubricant formulations. The compositions mentioned above reduce the abrasion phenomena in the components to be lubricated if they are added to mineral and synthetic lubricating oils, hydraulic fluids and lubricating greases.
