Abstract:
    Composition having improved water tolerance properties which is adapted for use as a functional fluid or lubricating composition. The composition is comprised of a major amount of a synthetic or mineral oil of lubricating viscosity and a minor amount of a water tolerance fix compound. The water tolerance fix compound is present in an amount which is effective to improve the water tolerance properties of the composition as a whole which amount is in the range of from about 0.1 parts by weight to about 5 parts by weight per 100 parts by weight of the oil. The water tolerance fix compound is a nitrogen-containing, phosphorus-free carboxylic acid derivative compound which is present in the oil along with 5 parts by weight of water or less per 100 parts by weight of the oil.
