ABSTRACT:
Disclosed herein are additives which are useful as dispersants and detergents in lubricating oils. In particular, this invention is directed toward polyamino alkenyl or alkyl succinimides which have been modified by treatment with a compound of the formula: ##STR1## wherein W is oxygen or sulfur; X is oxygen, sulfur or R.sub.5 N< wherein R.sub.5 is hydrogen, and alkyl of from 1 to 20 carbon atoms; and R.sub.4 is an alkylene group of from 2 to 5 carbon atoms or an alkylene group of from 2 to 5 carbon atoms substituted with from 1 to 3 alkyl groups of from 1 to 2 carbon atoms each with the proviso that both W and X are not both oxygen. The modified polyamino alkenyl or alkyl succinimides of this invention have been found to possess dispersancy and detergency in lubricating oils. These modified succinimides are also useful as dispersants and detergents in fuels.
