What can be added to fuel oil to reduce the pour point?

To reduce the pour point of fuel oil, both additives and kerosene are effective options. Additives specifically designed for fuel oils can lower the pour point by modifying the wax structure in the oil, enhancing its flow characteristics at lower temperatures. These pour point depressants are chemical agents that function at a molecular level, preventing the wax crystals from growing large enough to impede the fluidity of the oil.

Kerosene, on the other hand, can also be blended with fuel oil to achieve a lower pour point. It has a lower viscosity and pour point compared to heavier fuel oils, which helps in maintaining fluidity in colder conditions. When kerosene is mixed with fuel oil, it dilutes the overall temperature characteristics of the blend, making it less likely to solidify in low temperatures.

Hence, combining both additives and kerosene is a versatile approach to effectively manage the pour point of fuel oils, especially in colder climates or when storage temperatures are a concern.
