<p>A lubricating composition having improved anti-wear properties comprises: A. a lubricating oil basestock; B. a metal phosphate; C. a metal carbamate; and D. an alkyl hydroxy-aryl sulfide. The metal phosphate is preferably a dialkylphosphate, zinc compounds being especially suitable. From about 0.1 to about 1.0 wt.% (based on the basestock) is preferred. The metal carbamate is preferably a dithiocarbamate, more especially zinc compounds. From about 0.1 to about 1.3 wt.% is preferred.
