  • Individual oils meeting this final viscosity requirement can be used as such as the base stock or a mixture of petroleum derived natural oils and/or synthetic oils of differ- ing viscosities can be combined and blended to produce a mixed oil base stock meeting the final product target specification.
  • Additives are employed to bestow rust resistance, demulsibility, detergency, oxidation resistance, wear and extreme pressure resistance, friction modification, anti- foam protection, filterability and so forth to the oil and render it useful as an industrial machine oil.
  • the additive imparting rust resistance to the formulation consists of a mixture of metal synthetic alkyl aryl sulfonates and aliphatic substituted succinic acid or anhydride.
