Abstract: In the field of lubricating compositions, in particular to the Fuel Economy (FE) properties of lubricating compositions, there is disclosed the combined use of at least one derivative of molybdenum and at least one derivative of boron to maintain the Fuel Economy (FE) properties of a lubricating composition also including at least one base oil. Also disclosed is a use, within a lubricating composition including at least one base oil, of a combination of at least one derivative of molybdenum and at least one derivative of boron, and at least 30 ppm and at most 600 ppm of born boron relative to the weight of the lubricating composition to preserve the Fuel Economy (FE) properties of this lubricating composition.

Abstract: The present application concerns a method for separate lubrication of a drive system for a motor vehicle, the system including a compressor and an internal combustion engine including a top end and a bottom end that are coupled together, the method including: —lubricating the bottom end with a lubricating composition CL1 having an SAE J300 grade defined by the formula (X)W−(Y) in which X represents 0 or 5 and Y represents 4, 8, 12, 16 or 20; —lubricating the top end with a lubricating composition CL2 different from the lubricating composition CL1; and —lubricating the compressor with a lubricating composition CL2 or with a lubricating composition CL3 different from the lubricating compositions CL1 and CL2.

Abstract: Disclosed is a monophasic lubricating composition including a base oil, an oil chosen from the polyalkylene glycols (PAG) and a phase-change material, in particular water. The monophasic lubricating composition can be used, in particular, for lubricating a vehicle engine. It has improved thermal performance relative to the lubricant compositions of the prior art. It also helps reduce fouling of the engine parts.
