Abstract: The present invention relates to a lubricating composition comprising at least one base oil and at least one additive chosen from anti-wear additives, extreme pressure additives, antioxidants, anti-corrosion additives, metal deactivator additives, anti-foam agents, dispersants and mixtures thereof, said composition having a boron concentration less than or equal to 100 ppm by weight and a nitrogen concentration strictly greater than 100 ppm by weight and less than or equal to 500 ppm by weight, with respect to the total weight of the lubricating composition.

Abstract: The present invention relates to a method for preparing solid microcapsules, comprising the steps of: a) adding under agitation a composition C1 comprising at least one active material to a cross-linkable liquid composition C2, wherein the active material is an additive to be used in the oil industry, composition C1 and composition C2 being immiscible with each other, so that a first emulsion is obtained, said first emulsion comprising droplets of composition C1 dispersed in composition C2, b) adding under agitation the first emulsion obtained in step a) to a liquid composition C3, composition C3 and composition C2 being immiscible with each other, so that a second emulsion is obtained, said second emulsion comprising droplets dispersed in composition C3, c) loading the second emulsion obtained in step b) in a mixer which applies a homogeneous controlled shear rate to said second emulsion, said shear rate being from 1 000 s?1 to 100 000 s?1, so that a third emulsion is obtained, said third emulsion comprising

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 disclosure relates to a lubricant composition including: (a) an organomolybdenum compound, (b) one or more anti-wear and extreme pressure additives chosen from thia(di)azoles, (c) one or more phosphorus-containing or phosphor-sulfur-containing anti-wear and extreme pressure additives chosen from phosphites, phosphates, phosphonates, thiophosphates or thiophosphites, the lubricant composition having a weight content of molybdenum between 90 and 350 ppm. This is used for lubrication of gear boxes.
