ENGINE LUBRICANT FOR VEHICLES HAVING A HYBRID OR MICRO-HYBRID ENGINE

摘要

The present invention relates to the use of at least one polyalkylene glycol, particularly of at least one polyalkylene glycol obtained by copolymerizing ethylene oxides and propylene oxides, or of at least one polyalkylene glycol obtained by homopolymerizing propylene oxides, in a lubricant composition including at least one base oil for lubricating the internal combustion heat engines of vehicles having hybrid and/or micro-hybrid engines. The use of this type of polyalkylene glycol enables a reduction in the wear of the connecting-rod bearings of the internal combustion heat engine.
