A grease composition comprises a base oil and an aluminium complex soap thickener, with graphite, molybdenum di-sulphide, calcium carbonate and bismuth sulphide all included as additives. The composition exhibits advantageous load, wear and friction performance, especially in extreme pressure environments, and is particularly suitable for use on open gears.

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 either solubilized, liquified, 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 either be a lubricant in which the solubilized, liquified, 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.
