    Abstract: The present invention is directed to compositions prepared by reacting (a) an oil soluble polyalkylene polyamine containing at least one polyalkylene polymer chain having at least one double bond and which chain is attached to a nitrogen and/or carbon atom of the alkylene radical(s) connecting the amino nitrogen atoms with said alkaline polyamine having a molecular weight of the range of from about 600 to about 10,000 and (b) furan under Diels-Alder reaction conditions. The invention also relates to the use of the subject compositions as additives in an unleaded fuel gasoline compositions to reduce intake valve deposits in electronic port fuel injected engines.
