Kerosene would be rated as #1 Fuel Oil typically. Highly refined kerosene fraction is the typical primary component of jet fuel. More polar climates need at kerosene / naphtha mixture for jet fuel to lower the fuel freeze point. #4 Fuel Oil typically has a considerable waxy fraction used to feed FCCU or hydrocracking units after vacuum distillation, and has to be heated somewhere around 120Â°F to 150Â°F to be pumpable. I haven't seen any real demand for #4 fuel oil since the mid-1980's personally. Used drain oil is typically blended into #6 Fuel Oil if not re-refined.
