A phosphate complex of a borate ester provides wear- and friction-reducing performance to an engine or driveline device. The complex may be a pyroborate-hydrocarbyl-substituted phosphate adduct. Boric acid may be reacted with a diol to form an ester, then reacting said ester with an ammonium salt of phosphoric acid or a hydrocarbyl-substituted phosphoric acid. 2. The composition of claim 1 , wherein at least one of Rand Ris a hydrocarbyl group containing from about 4 to about 22 carbon atoms.3. The composition of claim 1 , wherein on each ring substituted with Rto Rindependently claim 1 , n is 0 or 1 claim 1 , and{'sup': 3', '4', '7', '7', '3', '4', '5', '6, 'sub': '2', '(i) one of Rand Ris —CH—O—C(O)—Rwhere Ris a hydrocarbyl group containing from about 8 to about 30 carbon atoms, and the other of Rand R, and each of Rand Ris chosen from hydrogen or a methyl group; or'}{'sup': 3', '4', '3', '4', '5', '6, '(ii) one of Rand Ris a hydrocarbyl group containing from about 4 to about 22 carbon atoms and the other of Rand Ris independently a hydrocarbyl group containing from about 4 to about 22 carbon atoms or hydrogen, and each of Rand Ris hydrogen.'}4.
