An additive composition to be incorporate with an oil base such as a petroleum-based lubricating oil. The additive includes the combination of a metal carboxylate, containing a metal such as bismuth, copper, zinc or manganese, and a carboxylic acid in a solvent system. The additive when incorporated with the oil base provides increased corrosion resistance, decreases "washout" capabilities of the oil from the lubricated metal and provides a minimum change of viscosity over a wide range of temperature.
