<p>A lubricant composition includes: (a) one or more base oils, (b) at least one comb polymer formed by a polyalkyl(meth)acrylate main chain, and hydrocarbon side chains including at least 50 carbon atoms, (c) at least one nitrogen-containing organic friction modifier chosen from the optionally alkoxylated fatty amines, fatty amides or imides obtained by the condensation of fatty amines and carboxylic acids, alone or in a mixture, (d) optionally, one or more organometallic organomolybdenum-type friction modifiers. This is used for the lubrication of 4-stroke gasoline or diesel engines of light vehicles, preferentially of hybrid vehicles.</p> |
