Disclosed is a lubricating engine oil composition for use in down-sized boosted engines comprising a lubricating oil base stock as a major component, and at least one silane-containing compound. Also disclosed is a method for preventing or reducing low speed pre-ignition in a direct injected, boosted, spark ignited internal combustion engine, and the use of at least one silane-containing compound in a lubricating engine oil composition for preventing or reducing low speed pre-ignition in a direct injected, boosted, spark ignited internal combustion engine.

A drilling mud is provided, the drilling mud comprising green diesel comprising de-oxygenated oil, water; and one or more fine particle solids. The green diesel may be formed from an edible oil or non-edible feedstock. The drilling mud fine particle solids comprise bentonite, barite, ferrophosphate ore, calcite, or siderite. The drilling mud may comprise stabilizing additives such as emulsifiers, weighting agents, fluid loss additives, alkali reserves, and viscosity regulators. In other embodiments, lubricants for drilling fluids comprise green diesel and lubricity additives such as solvents, esters, and surfactants. The lubricant may further comprise graphite or polytetrafluoroethylene. A slurry for use in oil and gas drilling operations comprises green diesel, polysaccharides or polyacrylamides, and a thickener such as silica, bentonite clay, and waxes. A wireline lubricant comprises green diesel, one or more block polymers, and one or more corrosion inhibitors.

The present invention relates to a coating composition that can produce an article having an inner surface and an outer surface, both of which are slippery, and a method for preparing the same. By using the coating composition according to the present invention, it is possible to produce the article having the inner surface and the outer surface, both of which are slippery, only with a simple process of molding and curing a polymer resin by the technique of the prior art. The article produced using the coating composition of the present invention can solve an ice removal on a surface of the machinery such as an aircraft and an automobile, a biofouling problem in a blood vessel, a problem requiring self-cleaning, and the like, and thus can be used in various industries.
