Only ultra low sulfur No. 1 diesel (No. 1 diesel with no more than 15 ppm sulfur) may be blended with ULSD fuel to improve cold weather performance. Kerosene should never be used to improve the low temperature operability of ULSD; its sulfur level is too high. In cold weather climates Mobil branded diesel fuels are blended with an additive in winter months to improve low temperature performance. This should eliminate the need for supplemental ULSD No. 1 blending in most circumstances.
