    Abstract: The present invention is a 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 prepared by reacting a nitrogen-containing phosphorus-free carboxylic acid (A) with an alkanol tertiary monoamine (B) to form an ester-salt reaction product. The water tolerance fix compound is present in the oil along with 5 parts by weight of water or less per 100 parts by weight of the oil.

    Abstract: A number of functional characteristics of a gear lubricant are improved by including within the lubricant an additive package comprised of (a) a treated zinc dithiophosphate and (b) an overbased carboxylate which is preferably borated. The additive preferably includes (c) an alkylamine, (d) a sulfurized olefin and (e) a polymeric foam inhibitor. The components of the package provide an interdependent synergistic improvement of numerous performance characteristics of the gear lubricant such as reducing copper strip corrosion, increasing thermal stability and reducing the amount of rust, and odor. The limited slip or anti-chatter performance of the oil is also improved.

    Abstract: Continuously variable transmissions are lubricated by supplying to the transmission a composition of an oil of lubricating viscosity and an oil-soluble zinc salt containing at least one hydrocarbyl group of at least 4 carbon atoms. The amount of the zinc salt is sufficient to provide an increased steel-on-steel dynamic coefficient of friction for the composition, being at least 0.125. The composition is substantially free from thiophosphate salts and exhibits a copper corrosion rating of 1B or better (ASTM-130).
