The gel point of a petroleum product is the temperature at which it gels and can no longer flow by gravity or be pumped through fuel lines. #2 diesel fuel is the most readily available grade of diesel and offers the best fuel performance on the market. However, it has a tendency to gel when the temperature drops. This can lead to engine power loss and even cause the engine to stall. The gel point of #2 diesel fuel is generally between 10 and 15 degrees Fahrenheit, but this can vary depending on the quality and makeup of the fuel. To prevent gelling, diesel additives can be used to lower the pour point of the fuel, keeping it fluid and injectable into the engine even in cold conditions.

What You'll Learn
The gel point of #2 diesel fuel is between 10 and 15 degrees Fahrenheit
To prevent these issues, it is recommended to use diesel additives, which can lower the pour point of the fuel and keep it fluid and injectable into the engine, even in extremely cold conditions. These additives also improve ignition and fuel lubrication, reducing friction and preventing engine damage. One such additive is kerosene, which is often mixed with #1 diesel to create winter diesel. However, kerosene can wear out the fuel pump, so it is not recommended to use high amounts in diesel engines.
Another way to prevent fuel gelling is to keep your fuel tanks full, reducing the air space inside the tank and minimising condensation that can lead to frozen fuel. Additionally, parking in a temperature-controlled environment can help.
It is worth noting that the gel point of #2 diesel fuel can vary depending on its blend. For example, biodiesel blends might gel at higher temperatures, while blended fuels that mix #1 and #2 diesel can perform well in lower temperatures. The cloud point of straight #2 diesel fuel is around 20 degrees Fahrenheit, which is when wax crystals begin to form and the fuel becomes visually cloudy.

The cloud point of #2 diesel fuel is 20 degrees Fahrenheit
The cloud point of a fuel is the temperature at which wax crystals begin to form, causing the fuel to become cloudy. This can happen at temperatures as high as 32 degrees Fahrenheit, but the average cloud point for #2 diesel fuel is around 20 degrees Fahrenheit. As temperatures continue to drop, the diesel approaches its pour point, the coldest temperature at which it can flow before freezing.
The cloud point of #2 diesel fuel can vary depending on its composition and how much paraffin it contains. It typically ranges from -18 to 20 degrees Fahrenheit. To prepare for colder temperatures, #2 diesel fuel can be blended with #1 diesel fuel, which has a cloud point of -40 degrees Fahrenheit. By increasing the percentage of #1 diesel fuel in the blend, the resulting mixture can withstand lower temperatures before reaching its cloud point.
Gelling of diesel fuel can cause significant issues for diesel engines. When diesel fuel gels, engine power loss occurs due to reduced fuel flow. In severe cases, the engine may stall, leaving drivers stranded in cold weather. To prevent gelling, diesel additives can be used, and diesel winterization best practices should be followed. Keeping fuel tanks full and parking in temperature-controlled environments can also help mitigate the chances of diesel fuel gelling.

#2 diesel fuel is the most readily available type
Diesel #2 is the most widely used type of diesel fuel. It has a higher energy content per gallon compared to Diesel #1, providing more power and better fuel economy. This makes it more efficient for long-distance travel and heavy-duty applications. It is also readily available at fuelling stations that offer low-sulphur diesel options. Diesel #2 is typically ultra-low-sulphur diesel (ULSD), containing 15 parts per million (ppm) or less of sulphur to meet environmental regulations and reduce emissions.
Diesel #2 is mostly known as "regular diesel" as it is the standard type of diesel fuel used by the majority of diesel engines. It is the standard fuel for most diesel engines and is the most common type of diesel fuel used in a diverse range of diesel-powered vehicles, equipment and machinery. It is also sometimes referred to as "straight #2".
The use of Diesel #2 is particularly common in warmer climates or weather. In very cold temperatures, a winterized diesel blend is recommended to prevent gelling. Diesel #2 has a cloud point of around 20°F (-6.6°C), and gelling can occur at temperatures between 10°F (-12.2°C) and 15°F (-9.4°C). Gelling can cause engine power loss, reduced power, poor performance, and lower fuel efficiency.
To prevent gelling in Diesel #2, it is recommended to use diesel additives and follow diesel winterization best practices. Keeping fuel tanks full and parking in a temperature-controlled environment can also help minimize the risk of gelling.

Blended diesel fuel combines #1 and #2 fuel
Diesel fuel is a complex mixture of hydrocarbons. In winter, wax particles within the fuel react to cold temperatures, causing the fuel to gel. This can lead to engine power loss, reduced power, poor performance, lower fuel efficiency, and even a stalled engine. To prevent this, diesel fuel is often treated with additives to lower its pour point, or the temperature at which it can flow before freezing.
One way to prevent diesel fuel from gelling in cold temperatures is to blend #1 and #2 diesel fuels. #1 diesel, also known as kerosene, has a lower gelling point than #2 diesel. By blending the two fuels, the mixture can withstand colder temperatures without gelling. This practice has been used for decades, especially in regions with sub-zero temperatures.
Blended diesel fuel combines #1 and #2 diesel fuels to create a mixture that can be used in colder temperatures. In extremely cold regions, a blend of half #1 and half #2 fuel may be used, along with additives for lubricity. In less severe cold, a blend of 70% #2 and 30% #1 fuel may be sufficient. The exact ratio of the blend can vary depending on the expected temperatures and the specific requirements of the vehicle.
The use of blended diesel fuel offers several benefits. Firstly, it reduces the chance of the fuel gelling in colder temperatures. Secondly, it provides sufficient energy components and lubricant properties, ensuring the vehicle's performance is not compromised. While fuel economy may be slightly impacted, it is still a preferable alternative to dealing with a stalled vehicle due to gelled fuel.
However, it is important to note that blending diesel fuels may not always be effective, especially with modern engines. Changes in diesel fuel compositions, such as the addition of red dye, biodiesel, and lubricity additives, can affect the blending process. Additionally, the use of kerosene in high amounts is not recommended as it can wear out the fuel pump and cause other issues. Therefore, it is crucial to consult fuel suppliers or experts to determine the appropriate blend and additives for specific vehicles and operating conditions.

Anti-gel additives can be used to prevent gelling
#2 diesel fuel generally gels between 10 and 15 degrees Fahrenheit, although it can gel at higher temperatures if the fuel has a high wax content. Gelling can also occur at lower temperatures, with some sources stating that #2 diesel fuel can gel at temperatures as low as -10 degrees Fahrenheit or even lower.
To prevent gelling, anti-gel additives can be used. These additives lower the temperature at which diesel starts to gel, helping to prevent fuel system blockages and ensure smooth engine operation. They are a cost-effective solution to prevent vehicle breakdowns and can save time and money. Anti-gel additives work by dissolving the gel and returning the fuel to a liquid state. They can also help improve fuel flow at low temperatures.
There are several anti-gel additives on the market, such as Hot Shot's Secret EDT+ Winter Defense and Diesel Winter Anti-Gel, which reduce fuel line freeze-ups down to -40 degrees Fahrenheit. Diesel Winter Anti-Gel lowers the fuel's cold filter plugging point (CFPP) to prevent fuel lines and filters from clogging. EDT+ Winter Defense is an everyday treatment that prevents the formation of clumps and allows fuel to flow freely at low temperatures.
Another popular anti-gel additive is Howes Diesel Treat, which is North America's number one trusted anti-gel and fuel conditioner. Diesel Treat is safe to use and does not contain any alcohol or harmful solvents. It has been proven to prevent gelling in even the coldest climates and provides added benefits such as improved lubricity and the prevention of deposits.
In addition to using anti-gel additives, there are other ways to prevent diesel fuel gelling. These include keeping fuel tanks full to minimize condensation and parking in a temperature-controlled environment whenever possible. Blended fuels, such as mixing #1 diesel (made with kerosene) and #2 diesel, can also help protect fuel in lower temperatures. However, it is important to note that using high amounts of kerosene in diesel engines is not recommended as it can cause issues with the fuel pump.
