A composition useful as a lubricating oil or fuel additive comprising at least one compound of the formula [Figure] (I) wherein each Ar is independently an aromatic group having from 4 to about 30 carbon atoms and from 0 to 3 optional substituents, each R is independently hydrocarbyl, R4 is a monovalent terminating group, each m is independently an integer ranging from 0 to about 10, x ranges from 0 to about 8, each Z is independently OH, lower alkoxy, (OR5)bOR6 or 0-R1, R2, R3, and R6 are each independently, H or hydrocarbyl, b ranges from 1 to about 30, c from 1 to about 3, and y from 1 to about 10, the sum m+c does not exceed the number of valences of the corresponding Ar available for substitution and at least one A is the group [Figure] (II) wherein each Rb, Rc, Rd and Re is independently H, hydroxyhydrocarbyl or hydrocarbyl, X is O, S or NRa wherein Ra is H, hydrocarbyl, hydroxyhydrocarbyl, aminohydrocarbyl or [Figure] (III) wherein each Y is [Figure] each R5 is independently a divalent hydrocarbyl group, each R7 is H, alkoxyalkyl, hydroxyalkyl, hydrocarbyl, aminohydrocarbyl, or N-alkoxyalkyl- or hydroxyalkyl- substituted amino-hydrocarbyl, a is a number ranging from 0 to about 100 and D is [Figure] (IV)
