A liquid composition for providing enhanced lubrication and wear protection, particularly under high-performance and/or extreme-pressure conditions. The composition comprises components that are solubilized, liquified, liquefacted, or sub-micronized, and are formulated to result in a stable, color-tunable composition that can be stored or implemented over extended periods of time without separation of solid components from the liquid. A composition can be a lubricant in which the solubilized, liquified, liquefacted, and/or sub-micronized components are comprised within a base oil, or an additive composition in which the components are formulated to be later added to a base oil. Suitable base oils are industrial, automotive, or open gear oils such as those used in the oil and gas industry, sugar mills, or in rock crushers; rock drill, pneumatic, and air tool oils; anti-seize compounds; cutting, gun, engine, air compressor, or bearing oils; slideway lubricants; and oven, kiln, foundry, metalworking, metalforming, or aerospace lubricants.
