Abstract: The invention relates to a lubricant composition comprising at least:



a base oil,
a friction modifier comprising molybdenum,
a boron-containing dispersant,
a polymer comprising repeating units which can be obtained by polymerization of monomers (a) with the formula (I):










wherein:
R1 represents a hydrogen atom or a methyl moiety,
X1 represents a moiety chosen from: —O—, —O(AO)m, or —NH—, each moiety A independently representing a C2-C4 alkylene moiety and m represents an integer from 0 to 10.
R2 is a polybutylene moiety, and
p is equal to 0 or 1.
