A method for improving wear control in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and encapsulated microscale particles, as a minor component. The minor component contains no sulfur or phosphorus. The encapsulated microscale particles include an encapsulating material and a core material encapsulated by the encapsulating material. The core material includes at least one metal salt selected from a metal oxide, metal hydroxide, metal carbonate, or mixtures thereof. The encapsulating material is derived from a carboxylic acid selected from an aliphatic carboxylic acid, a cycloaliphatic carboxylic acid, an aromatic carboxylic acid, and mixtures thereof. The lubricating oils are useful in internal combustion engines.

A wear and/or friction reducing additive for a lubricating fluid in which the additive is a combination of a moderately hydrophilic single-phase compound and an anti-wear and/or anti-friction aqueous salt solution. The aqueous salt solution produces a coating on boundary layer surfaces. The lubricating fluid can be an emulsion-free hydrophobic oil, hydraulic fluid, antifreeze, water, or a water-based lubricant. Preferably, the moderately hydrophilic single-phase compound is sulfonated castor oil and the aqueous salt solution additionally contains boric acid and zinc oxide. The emulsions produced by the aqueous salt solutions, the moderately hydrophilic single-phase compounds, or the combination thereof provide targeted boundary layer organizers that significantly enhance the anti-wear and/or anti-friction properties of the base lubricant by decreasing wear and/or friction of sliding and/or rolling surfaces at boundary layers.

A release agent and method of use for preventing the adhesion of materials to equipment in various industries including construction, mining, and asphalt. The release agent can include oil, surfactant, and in increased level of free fatty acids that can combine with alkali and/or alkaline earth metals in the materials to form a metal/fatty acid salt that prevents adhesion and material build up.
