The present patent application relates to a method for reducing wear and tear on mechanical parts that are in contact with each other in an internal combustion engine by using a lubricating composition comprising:

Lubricating composition for reducing wear and tear on dlc parts used in internal combustion engines

The present invention relates to a dinuclear molybdenum complex with ligands selected from fatty tertiary amines of formula (I):R&#x2014;[(CH)R][(CH)R]&#x2003;&#x2003;(I)wherein

Dinuclear molybdenum complex and use of same in lubricating compositions

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.

Long duration fuel economy lubricating composition
