This invention is to a lubricating or fuel oil composition containing polyolefinic succinimide polyamine alkyl acetoacetate adducts of the general formula: ##STR1## wherein Z.sup.1 and Z.sup.3 are moities of the formula: ##STR2## Z.sup.2 is a moiety of the formula: ##STR3## wherein R.sup.2, R.sup.3 and R.sup.4 are alkylene of from 1 to 6 carbon atoms, m is an integer of from 1 to 5, each A' is H, A and the moiety: ##STR4## wherein A" is H or A, R.sup.3 is as defined above, R.sup.6 is alkylene of from 1 to 6 carbon atoms, T.sup.1 and T.sup.2 are ##STR5## wherein B' is substituted or unsubstituted alkyl or aryl-containing group, n.sup.1, n.sup.2, n.sup.3 and n.sup.4 are from 0 to 10 their sum being from 3 to 10, R.sup.1 and R.sup.5 are an olefin polymer, and A comprises a tautomeric substituent of the formula: ##STR6## wherein R.sup.10 is substituted or unsubstituted alkyl or aryl containing groups.

The adduct additives are especially useful in concentrates, lubricating oil or fuel oil compositions as dispersants. The formulations have excellent coild flow properties compared to similar formulations not containing the inventive adduct.
