摘要： The present invention relates to lubricant compositions comprising: (a) one or more polyalkylene glycol base oils obtained by polymerization or copolymerization of alkylene oxides comprising from 3 to 8 carbon atoms, including at least one butylene oxide and (b) at least one detergent chosen from salicylates or phenates. The present invention also relates to the use of a lubricant composition according to the invention as engine oil, preferably as oil for the engines of petrol or diesel motor vehicles. The present invention also relates to the use of a group of additives for an engine lubricant comprising polyalkylene glycol bases obtained by polymerization or copolymerization of alkylene oxides comprising from 3 to 8 carbon atoms. The present invention also relates to the use of at least one additive chosen from salicylates, phenates, dithiocarbamates, amine-based or phenol-based antioxidants, preferably from salicylates or phenates, for reducing the Noack volatility of the base oils of polyalkylene glycol type, obtained from alkylene oxides comprising from 3 to 8 carbon atoms.

摘要： The present invention concerns engine lubricant compositions comprising at least one base oil, at least one polymer viscosity index improver and at least one polyalkylene glycol, obtained by polymerisation or copolymerisation of alkylene oxides comprising from 3 to 8 carbon atoms, including at least one butylene oxide, the quantity of polyalkylene glycol being 1 to 28% by mass relative to the total mass of the lubricant composition. Using at least one polyalkylene glycol, obtained by polymerisation or copolymerisation of alkylene oxides comprising from 3 to 8 carbon atoms, including at least one butylene oxide, in a base oil, improves engine cleanliness while not increasing, or indeed while decreasing, the consumption of petrol or diesel fuels by the engine.

摘要： The invention relates to the field of lubricating compositions, in particular the
fuel economy (FE) properties of the lubricating compositions. The invention relates to the combined use of at least one derivative of molybdenum and of at least one derivative of boron in order to preserve the
fuel economy (FE) properties of a lubricating composition also comprising at least one base oil. The invention also relates to the use, within a lubricating composition also comprising at least one base oil, of a combination of at least one derivative of molybdenum and of at least one derivative of boron, and at least 30 ppm or at most 600 ppm of boron with respect to the weight of lubricating composition to preserve the
fuel economy (FE) properties of this lubricating composition.-
