ABSTRACT:
This invention relates to processes and compositions for color stabilized distillate fuel oils which comprises an effective color stabilizing amount of (a) a tertiary amine having the formula ##STR1## wherein R and R' are the same or different alkyl groups having one to about six carbon atoms, and (b) a hydroxylamine having the formula ##STR2## wherein R and R' are the same or different and are hydrogen, alkyl, alkaryl or aralkyl groups, wherein the weight ratio of (a):(b) is from about 1:1 to about 99.7:0.3. Preferably, the alkyl, alkaryl and aralkyl groups of the hydroxylamine have from one to about twenty carbon atoms. It is further preferred that (a) is N,N-dimethylcyclohexylamine and (b) is N,N-diethylhydroxylamine.
