The wear characteristics of metal‐organic chelate additives containing tin bonded to aliphatic dicarboxylic acids were investigated on a reciprocating motion test machine in lubrication of a steel‐bronze contact. It was found that both the valence state of the tin and the chain lengths of the dicarboxylic acids affected the wear results. All the compounds reduce wear effectively and, at pressures below 1.76 MPa, they assure zero ZDTP and SnDTP additives in the steel‐steel concentrated contact using the standard four‐ball machine.
