As a fuel expert with years of experience in the industry, I'd like to shed some light on the phenomenon of diesel fuel gelling, which is a critical issue faced during cold weather conditions.
Diesel fuel, a complex mixture of hydrocarbons, contains paraffin waxes that are susceptible to changes in temperature. When the temperature drops, these paraffins begin to crystallize, which is the first step towards gelling. The process is a physical change where the wax molecules arrange themselves in a more ordered structure, leading to a loss of fluidity in the fuel.
The critical temperature at which diesel fuel starts to show signs of gelling is around 32 degrees Fahrenheit (0 degrees Celsius). At this point, the wax in the fuel begins to crystallize, but the fuel is still relatively fluid. However, as the temperature continues to decrease, the wax content increases, and the fuel's viscosity rises significantly.
The actual gelling point, where the fuel becomes semi-solid and starts to clog the fuel system, typically occurs at temperatures between 10 to 15 degrees Fahrenheit (-12 to -9 degrees Celsius). At these temperatures, the paraffin waxes solidify more completely, forming a gel-like substance that can impede the flow of fuel through the engine's fuel lines and filters.
Gelling can lead to a variety of problems, including poor engine performance, starting difficulties, and in severe cases, complete engine shutdown. It's crucial for diesel vehicle owners and operators to be aware of the potential for gelling and to take preventive measures, such as using diesel fuel additives designed to lower the gelling point, ensuring proper fuel tank insulation, and selecting the correct diesel fuel grade for the expected low temperatures.
Furthermore, it's important to note that the gelling point can vary depending on the specific composition of the diesel fuel, which includes factors such as the concentration of paraffin waxes and the presence of other additives. Some diesel fuels are formulated with cold-flow improvers that can help prevent gelling at lower temperatures.
In summary, understanding the behavior of diesel fuel in cold temperatures is essential for maintaining the reliability and performance of diesel engines. By being proactive and taking the necessary precautions, diesel operators can mitigate the risks associated with diesel fuel gelling.

Diesel fuel gelling happens when the paraffin usually present in diesel starts to solidify when the temperature drops. At 32 degrees, the wax in liquid form will crystallize and leave the fuel tank clouded. At 10-15 degrees, it will finally start to gel and clog the tank and fuel filters.
