Stable low-sulfur diesel blend of an olefinic blend component, a low-sulfur blend component, and a sulfur-free antioxidant

A blended diesel fuel comprising:

• a) a Fischer Tropsch diesel fuel fraction comprising
• i) olefins in an amount of 25 to 80 weight %,
• ii) non-olefins in an amount of 20 to 75 weight %, wherein the non-olefins comprise greater than 50 weight % paraffins, wherein the paraffins have an i/n ratio of less than 1;
• and
• iii) oxygenates in an amount of at least 0.012 weight %;
• b) a diesel fuel fraction selected from the group consisting of a hydrocracked Fischer Tropsch derived diesel, a hydrotreated Fischer Tropsch derived diesel, a hydrocracked petroleum derived diesel, a hydrotreated petroleum derived diesel, and mixtures thereof;
• c) an effective amount of a sulfur-free antioxidant;
• and
• d) sulfur in an amount of less than 1 ppm,
• wherein the blended diesel fuel has a reflectance as measured by ASTM D6468 of greater than 65% when measured at 150° C. for 90 minutes and a peroxide number of less than 5 ppm after storage at 60° C. for four weeks.
