Disclosed is a lubricant composition including: at least one base oil; at least one olefin copolymer; at least one detergent; and at least one hydrogenated and linear styrene/butadiene copolymer. Also disclosed is the use of this composition for reducing the fuel consumption of an engine and for improving the cleanliness of a 4-stroke or 2-stroke, preferably 4-stroke marine engine, or of a stationary engine.

A gear fluid composition for lubricating a driveline including organic sulfide compounds effective to achieve passing friction, extreme pressure, and copper corrosion.

The invention relates to lubricating greases based on alkali metal soaps and/or earth-alkali metal soaps and metal complex soaps based on (R)-10-hydroxyoctadecanoic acid and to the use thereof.

The present disclosure relates to a lubricant composition comprising a first phosphorus compound, a second phosphorus compound, and a third phosphorus compound, wherein the first phosphorus compound is present in the lubricant composition in an amount to provide between about 120 and 350 ppm phosphorus. The lubricant composition may provide robust anti-wear and reduced pitting.

A crankcase lubricating oil composition for the crankcase of a spark-ignited or compression-ignited internal combustion engine, comprising a magnesium-containing detergent, in an amount sufficient to provide from 200-4000 ppm magnesium to the lubricating oil composition, in combination with an oil-soluble or oil-dispersible molybdenum compound in an amount sufficient to provide from 600-1500 ppm molybdenum atoms to the lubricating oil composition, and with an oil-soluble or oil-dispersible boron-containing compound in an amount sufficient to provide from 200-600 ppm boron atoms to the lubricating oil composition to improve the friction and fuel economy performance.

The present invention relates to a low friction member having seaweed-type nanotubes, the nanotubes which protrude like seaweed on the surface of a base material being concentrated in the moving direction of a sliding member, thereby improving the fluidity of a liquid lubricant, thus enabling the effective reduction of surface friction.

Such present invention comprises: a base material which has a plurality of dimples formed on the surface thereof so as to reduce friction occurring due to the surface contact of a sliding member; a fixing material which is filled inside the dimples; nanotubes which are buried in the fixing material and protrude to the outside by means of the surface processing of the fixing material; and a liquid lubricant which is coated on the surface of the base material, wherein, as the protruding nanotubes become concentrated in the moving direction of the sliding member, the fluidity of the liquid lubricant is improved, thereby enabling the effective reduction of surface friction.

This invention relates to the use of a metallic or non-metallic detergent which is a hydrocarbyl-substituted salicylic acid or a derivative thereof in a non-aqueous lubricant composition as an inhibitor of lead corrosion associated with ashless, organic ester, anti-wear additives and/or friction modifiers.

The present invention relates to a low-friction member imitating shark skin and a manufacturing method therefor, the low-friction member implementing a structure similar to shark skin and having riblets by stacking, in layers, composite particles formed by attaching spherical particles on the surfaces of plate-shaped particles, and thus the low-friction member has excellent low-friction characteristics. The present invention comprises: a base plate; plate-shaped particles stacked in layers on the surface of the base plate in the form of scales; and a plurality of spherical metal lubricating particles having a size smaller than that of the plate-shaped particles, and coated on the surfaces of the plate-shaped particles, wherein the metal lubricating particles are arranged in the form of a bridge connecting the base plate and the plate-shaped particles, and the plate-shaped particles to each other.
