May I continue to blend No. 1 diesel (kerosene) with my diesel fuel to improve cold weather performance?
A. For regulated parties in the fuel distribution chain (including retailers and fleet operators), only Ultra Low Sulfur Kerosene (No. 1 diesel with no more than 15 ppm sulfur) may be blended with ULSD without downgrading the fuel. EPA Winterization Standards Letter 11-30-07 Individual vehicle owners may add Low Sulfur (up to 500 ppm sulfur) No. 1 diesel to their vehicle’s fuel tank(s), as long as the vehicle does not require ULSD. Regardless of sulfur levels, the blend ratios will remain the same. Like ULSD, Ultra Low Sulfur Kerosene may not be available in all areas. Consumers are advised to check the pump labels and vehicle labels to ensure they are refueling with the proper diesel fuel consistent with their vehicle warranties and using kerosene with the correct sulfur level when blending.
