The disclosure relates to a dye-stable furnace fuel composition comprising: about 10 to 99 parts by volume of a mineral oil component having an effective boiling range from about 160° C. to about 380° C.; about 1 to 90 parts by volume of a biocomponent fuel component comprising C1-C5 alkyl esterified fatty acids from renewable sources; one or more azo dye components present in an amount from about 0.5 mg/kg to about 5 mg/kg, relative to the total fuel composition; and a tert-butyl-functionalized hydroquinone antioxidant component present in an amount of at least about 50 vppm, relative to the fuel composition, wherein the fuel composition exhibits an increased dye stability, relative to a fuel composition having similar mineral oil and biocomponent fuel components and identical azo dye component(s), but having a different or no antioxidant component.
