ABSTRACT:
A fuel additive having the formula: ##STR1## wherein A.sub.1 is a thioether, a sulfoxide, a sulfone, a sulfonic acid, a sulfonamide, a nitrile, a carboxylic acid or ester, or a carboxamide; R.sub.1 and R.sub.2 are independently hydrogen, hydroxy, lower alkyl or lower alkoxy; R.sub.3 and R.sub.4 are independently hydrogen or lower alkyl; n is an integer from 0 to 100; and when n is 0 to 10, R.sub.5 is polyalkyl having an average molecular weight of 450 to 5,000; and when n is 5 to 100, R.sub.5 is hydrogen, alkyl, phenyl, aralkyl, alkaryl or an acyl group having the formula: ##STR2## wherein R.sub.6 is alkyl, phenyl, aralkyl or alkaryl; R.sub.7 and R.sub.8 are independently hydrogen, hydroxy, lower alkyl or lower alkoxy; A.sub.2 is a thioether, a sulfoxide, a sulfone, a sulfonic acid, a sulfonamide, a nitrile, a carboxylic acid or ester, or a carboxamide; and x and y are independently integers from 0 to 10; with the proviso that when n and x are both 0, then A.sub.1 may not be a carboxylic acid or ester, or a carboxamide.
