    Abstract: Disclosed are additives which are useful as dispersants in marine crankcase oils, hydraulic oils, and lubricating oils. In particular, disclosed are polyamino alkenyl or alkyl succinimides wherein one or more of the nitrogen of the polyamino moiety is substituted with: ##STR1## wherein R.sub.4 is alkylene of from 1 to 6 carbon atoms; m is an integer of from 0 to 2; R.sub.5 is alkylene of from 2 to 5 carbon atoms; p is an integer of from 1 to 100; R.sub.6 is selected from the group consisting of hydrogen and hydrocarbyl of from 1 to 30 carbon atoms; and with the proviso that if m is one or two then R.sub.6 is hydrogen.
