A dispersant includes the reaction product of an amine and at least one equivalent of glycidyl ether where the amine is selected from a group consisting of aminoethylpiperazine, bis(2-(piperazin-1-yl)ethyl)amine, 4,4′-methylenebiscyclohexylamine, m-xylenediamine, diethylenetriamine, and triethylenetetramine and where the glycidyl ether has the structure (A), where R is selected from aromatic carbon chains, non-aromatic carbon chains and polyalkylene glycol groups. The dispersant is useful in a lubricant with a base oil for increasing soot dispersibility of the lubricant.
