  • This invention relates to stabilising compositions for lubricant base stocks and lubricant formulations.
  • lubricant base stocks such as mineral and synthetic base oils chosen from Group I, Group II, Group III, Group IV and Group V base stocks as classified by the American Petroleum Institute, as well as natural and synthetic esters including polyol esters, more particularly, but not limited to automotive oils, circulatory oils, gear oils, greases, hydraulic fluids, turbine fluids and metal working fluids.
  • lubricant formulations is meant a lubricant base stock as described above, plus additional additives including but not limited to antioxidants, rust inhibitors, metal passivators, ashless dispersants, antiwear additives, extreme pressure additives and detergents, viscosity index improvers and antifoam agents.
  • a stabilising composition for lubricant base stocks and lubricant compositions comprises:
