Sour sulfhydryl group containing oils are treated with an effective amount of a sweetening, hydrogen sulfide vapor reducing quaternary ammonium compound of the formula ##STR1## (a) wherein (i) R.sup.1, R.sup.2 and R.sup.3 are hydrocarbon groups including alkyl, aryl, alkaryl or arylalkyl groups, of up to 24 carbon atoms, and if an alkyl group, may include a cycloalkyl; with the proviso that two of R.sup.1, R.sup.2 and R.sup.3 may be in saturated heterocyclic ring which includes said nitrogen atom and may also include an oxygen atom; and (ii) at least one of R.sup.1, R.sup.2 and R.sup.3 has two or more carbon atoms; and (b) wherein R.sup.4, R.sup.5, R.sup.6 and R.sup.7 independently are hydrogen or a hydrocarbon group of up to six carbon atoms, with the proviso that two of R.sup.4, R.sup.5, R.sup.6 and R.sup.7 may be in a cycloalkane ring. The compounds used in this treatment are especially suitable for high boiling, heavy residual fuels under low mix conditions.
