ABSTRACT:
The load-carrying capacity of liquid lubricants having a kinematic viscosity of 2 to 1500 mm.sup.2 /s at 40.degree. C. can be substantially improved by the addition of oil-insoluble, dispersible aromatic compounds which are chlorine-substituted in the nucleus. The compounds, which consist of 1 to 4 completely unsaturated or partially saturated aromatic moieties which may contain hetero-atoms and are linked to one another through a simple direct bond, a double bond or through --O--, --S--, --N(R)--, --N.dbd., alkylene, --NHCO--, --N.dbd.CH--, --N.dbd.N--, --N.dbd.NCH(COCH.sub.3)CONH, --CH.dbd.N--N.dbd.CH-- or .dbd.N--(Y)--N.dbd., contain from 2 to 24 aromatic chlorine atoms. The combination of the additives of the invention with conventional antiwear additives has been found to be particularly advantageous.
