First Claim
Patent Images
1. A fuel composition comprising a hydrocarbon boiling in the gasoline or diesel range and from 10 to 10,000 parts per million of a polyamino alkenyl or alkyl succinimide wherein one or more of the nitrogens of the polyamino moiety is substituted with ##STR31## wherein R4 is selected from the group consisting of hydrocarbyl of from 1 to 30 carbon atoms, --R5 (OH)t wherein R5 is hydrocarbyl of from 2 to 20 carbon atoms and t is an integer from 1 to 6 with the proviso that there is no hydroxy substitution on the hydrocarbyl carbon atom attaching the --R5 (OH)t group to the oxy atom of the ##STR32## moiety and with the further proviso than when t is greater than one, the hydroxy groups are not attached to the same carbon atom and the number of carbon atoms in the R5 group is minimally equal to t+1, and --(R7 O)s H wherein R7 is alkylene of from 2 to 5 carbon atoms and s is an integer from 2 to 100.
