A composition and a method for reducing rust in machines using lubricating oils by employing a lubricating oil formulation comprising a major amount of a base oil stock having a viscosity in the ISO 10 to 1500 grades range and a minor amount of an additive comprising a metal synthetic alkylated aryl sulfonate and aliphatic substituted succinic anhydride or acid. The formulation exhibits a high level of rust inhibiting performance, while not adversely affecting any other desirable lubricating oil properties.
