Abstract: A lubricating composition includes one or more base oils, at least one dimercaptothiadiazole derivative, at least one ethylene and alpha-olefin copolymer and at least one amine thiophosphate. The composition can be used for lubricating transmissions such as gearboxes and axles, preferably the manual gearboxes of motor vehicles and enable a reduction in the fuel consumption of vehicles, in particular of motor vehicles, due to the combination of the ethylene and alpha-olefin copolymer, dimercaptothiadiazole derivative and amine thiophosphate which decreases the coefficient of friction of the lubricating composition.

Abstract: The present invention relates to a lubricant composition comprising a dispersant of high molecular weight and metal nanoparticles. The lubricant composition according to the invention simultaneously has good stability and good anti-flaking properties.

Abstract: A lubricating composition includes at least one base oil, at least one compound including a dithiocarbamate group, at least one compound including a phosphite group and at least one compound including a dithiophosphate group. The lubricating composition simultaneously has good anti-wear and extreme-pressure properties, a low coefficient of friction and good anti-seizing properties. The lubricating composition can be used for lubricating transmissions such as gearboxes, axles, preferably the manual gearboxes of motor vehicles.

Abstract: The invention relates to a method for improving properties of protection against spalling of transmission lubricating compositions containing sulphur-containing and sulfur-phosphorous compounds comprising a step for adding into the initial transmission lubricating composition, compounds (c) reducing by at least 5% the active sulfur mass content, as measured by the ASTM D1662 standard, in the final composition.

Abstract: The subject of the disclosure concerns microcapsules including a core containing one or more alkali metal borates, optionally hydrated, dispersed in one or more lubricating base oils of mineral, synthetic or natural origin, and a polymer shell. Another subject of the disclosure is a lubricating oil including microcapsules. A further subject of the disclosure is the use of microcapsules according to the disclosure as anti-wear and/or extreme pressure additive for lubricant compositions. A further subject of the disclosure is a method for preparing microcapsules by interface polymerization.
