Abstract

The present disclosure relates to lubricant compositions for an engine, including at least one base oil, at least one polymer for improving the viscosity index, at least one organomolybdenum compound, and at least one polyalkylene glycol, obtained by polymerizing or copolymerizing alkylene oxides including from 3 to 8 carbon atoms, at least of which is butylene oxide, the polyalkylene glycol content being from 1 to 28% by weight relative to the total weight of lubricant composition. The use of at least one polyalkylene glycol, obtained by polymerizing or copolymerizing alkylene oxides including 3 to 8 carbon atoms, at least one of which is butylene oxide, in a base oil enables a reduction in the wear of the connecting-rod bearings of the thermal internal combustion engines of vehicles with hybrid and/or micro-hybrid engines.
