Diesel fuel contains paraffin wax, which helps engines generate more power and efficiency. However, in freezing temperatures, the wax crystallizes, thickens the fuel, and eventually clogs the fuel filter and lines, causing the engine to shut down. This process is known as diesel fuel gelling, and it typically occurs when temperatures drop below 32 degrees Fahrenheit. To prevent this, you can use additives or anti-gel supplements, store your vehicle in a heated environment, or mix kerosene with your diesel fuel to lower its freezing point.

Use anti-gel fuel additives to prevent fuel line freeze-ups
Diesel fuel contains paraffin wax, which improves its viscosity and lubrication. However, in freezing temperatures, the wax solidifies and turns into a cloudy mixture, eventually leading to diesel fuel gelling. This can cause fuel line freeze-ups and clog your engine's fuel filters and lines, stopping fuel from flowing and rendering your engine useless.
To prevent this, you can use anti-gel fuel additives, which are easy to use – you just top off your fuel tank with the treatment. Anti-gel additives drop the freezing point of diesel fuel so that it is less likely to freeze in cold temperatures. They are designed to lower the Cold Filter Plugging Point (CFPP), which is the lowest temperature at which fuel will still flow through a specific filter.
Hot Shot's Secret offers various anti-gel additives, such as EDT+ Winter Defense and Diesel Winter Anti-Gel, which reduce fuel line freeze-ups down to -40 °F. Diesel Winter Anti-Gel lowers your fuel's CFPP to prevent your fuel lines and filters from clogging. It also boosts your fuel's cetane number and improves detergency, stability, lubricity, and winter operability. EDT+ Winter Defense is an everyday treatment with anti-gel properties that prevents the formation of clumps and allows fuel to flow freely at low temperatures.
Fuel Ox also offers anti-gel additives, such as Fuel Ox Cold Charge, which prevents against fuel gelling, and Fuel Ox Heat Bomb, an emergency fuel treatment designed to restore the flow of frozen fuel lines.

Switch to No. 1 fuel diesel, which doesn't contain paraffin wax
Diesel fuel contains paraffin wax, which improves its viscosity and lubrication. However, in freezing temperatures, the wax begins to solidify, turning into a cloudy mixture. This eventually leads to diesel fuel gelling, which can clog fuel filters and lines, stopping fuel flow and rendering your engine useless.
No. 2 diesel fuel, which is typically used in vehicles, contains paraffin wax. When temperatures drop below 32 degrees Fahrenheit, the wax starts to crystalize, and at around 14-15 degrees Fahrenheit, it completely crystallizes, causing fuel filters to clog.
To prevent diesel fuel from gelling, you can switch to No. 1 diesel fuel, which does not contain paraffin wax and can withstand temperatures as low as -40 degrees Fahrenheit (-40 degrees Celsius). This is a significant advantage in colder regions, where No. 1 diesel may be more readily available. However, it's important to note that No. 1 diesel may not be available in warmer regions, and it may also have some disadvantages, such as reduced fuel mileage and efficiency.
If you choose to switch to No. 1 diesel, it's important to ensure that your engine is compatible with this type of fuel. Additionally, you may need to take into account the availability and cost of No. 1 diesel in your area.
Overall, switching to No. 1 diesel fuel that doesn't contain paraffin wax is an effective way to prevent diesel fuel from gelling in freezing temperatures, but it's important to consider the limitations and suitability for your specific situation.

Store your vehicle in a heated garage or use a block heater
If you live in a region where temperatures consistently drop below freezing, storing your vehicle in a heated garage is an effective way to prevent diesel fuel gelling. By maintaining a warm environment, you eliminate the risk of freezing temperatures affecting your vehicle's fuel system.
A heated garage, particularly one with climate control, ensures that your vehicle's fuel remains in a liquid state and flows freely through the fuel filters. This method is ideal because it addresses the root cause of the problem by removing the exposure to cold temperatures.
However, it is understandable that not everyone has access to a heated garage. In such cases, an alternative solution is to use a block heater, which is a modern device designed to protect your vehicle from frigid temperatures. A block heater is installed directly on the engine, providing targeted heat to keep the fuel from freezing. While this option may result in higher electricity costs, it is an effective way to safeguard your vehicle's fuel system during cold weather.
Additionally, there are other creative ways to apply heat and protect your vehicle. One method involves placing a series of light bulbs under the vehicle, emitting heat upwards. Another approach is to wrap the vehicle in a tarp and direct a heater towards it, creating a localized warm environment. These innovative solutions demonstrate the importance of heat in preventing diesel fuel issues during freezing temperatures.
By implementing these strategies, you can effectively prevent diesel fuel gelling and ensure the smooth operation of your vehicle, even in extremely cold conditions.

Mix diesel with kerosene, which has a lower freezing point
Kerosene has a lower freezing point than diesel, typically freezing at around −40°C/-40°F. This makes it a good option to mix with diesel fuel to lower the freezing temperature of the mixture.
Mixing diesel with kerosene is a common solution to prevent diesel fuel from gelling at low temperatures. This method involves modifying the fuel mixture itself, which can be done by mixing kerosene with diesel fuel. The amount of kerosene added will determine the extent of the freezing point reduction. For example, adding 10% kerosene will lower the cold filter plugging point of a diesel fuel blend by five degrees. In extremely cold weather, it may be more cost-effective to use kerosene as a mixer than a cold flow polymer.
However, there are some disadvantages to using kerosene. Firstly, it is considered a polluting fuel by the World Health Organization (WHO) due to its smoke containing particulate matter that can be harmful to health. Additionally, kerosene has reduced fuel mileage and efficiency, and it may not be readily available in all regions. It is also a harsher fuel that lacks lubrication, which can damage diesel injector pumps unless a lubricant is added.
While kerosene can be effective in preventing diesel fuel from freezing, it is generally recommended to use additives, lubricants, and winter-safe diesel engine oil to maintain engine health and performance.
