Diesel fuel is prone to gelling in cold temperatures, which can cause engine issues such as loss of power, hard starts, or even the inability to start the engine. To prevent this, diesel fuel can be treated with anti-gel additives, which are essential in cold climates. While it is possible to overtreat diesel fuel with anti-gel, it is generally not harmful to the engine. However, it may cause issues such as reduced power and hard starting. In extremely cold temperatures, diesel fuel may require additional treatment to prevent gelling. This is particularly important in regions with consistently cold temperatures or when travelling between warm and cold climates.

What You'll Learn
Diesel fuel will cloud before freezing
Diesel fuel contains paraffin, a waxy substance that improves lubricity and viscosity. However, in cold weather, paraffin wax thickens and crystallizes, causing the fuel to become cloudy. This process is known as reaching the "cloud point". The cloud point for diesel fuel can vary depending on factors such as the type of diesel, the amount of paraffin present, and any other blends of diesel mixed with the fuel. Once the cloud point is reached, the fuel becomes resistant to flow.
As temperatures continue to drop, the fuel will reach the "pour point", where it thickens and can no longer flow properly. The cloud point can begin at temperatures as high as 32°F (0°C), but generally starts at 20°F (-7°C) for #2 diesel fuel. The pour point is usually 6°F to 10°F (about -14°C to -12°C) lower than the cloud point.
The next stage is the "Cold Filter Plugging Point" (CFPP), where the crystallized wax begins to clog fuel filters, preventing the engine from running. This typically occurs 3°F to 5°F (about -16°C to -15°C) below the cloud point. Finally, the fuel reaches its "gel point", where it has completely solidified and can no longer flow. This usually happens around 10°F to 15°F (-12°C to -9°C).
To prevent diesel fuel from gelling, you can use heat to keep the fuel and engine warm. This can be achieved by storing the vehicle in a climate-controlled garage or using light bulbs, heaters, or block heaters. Another method is to modify the fuel mixture by adding kerosene, which has a lower gelling point than diesel, or using anti-gel supplements like Power Service Diesel Fuel Supplement +Cetane to lower the cloud point and gelling point.
It is important to note that diesel fuel gelling only occurs at very cold temperatures, and issues at temperatures above 10°F to 15°F (-12°C to -9°C) are likely due to ice rather than gelling.

Anti-gel is essential in cold climates
Diesel fuel is prone to gelling in cold climates, which can cause serious issues for your engine. Gelling occurs when the temperature drops, and the fuel begins to cloud and thicken, eventually freezing. This can result in a loss of power, hard starts, or even the inability to start the engine at all. In extremely cold temperatures, diesel fuel may fully gel, leading to smoke and potential engine damage.
To prevent gelling, it is essential to use an anti-gel additive in your diesel fuel. Anti-gel additives are designed to keep the fuel fluid and flowing smoothly, even in the coldest temperatures. This is particularly important in regions with consistently cold temperatures, such as the Midwest and the far north. By treating your diesel fuel with an anti-gel, you can ensure that your engine will start and run smoothly, even in the depths of winter.
One popular option for anti-gel treatment is Howes Diesel Treat, which is trusted by many diesel vehicle owners. It has been proven to prevent gelling, even in the coldest weather, and provides added benefits such as increased lubricity and the prevention of deposits. Howes Diesel Treat is safe to use, as it does not contain any alcohol or harmful solvents, and it will not void manufacturers' warranties. It is a reliable choice to protect your engine and ensure your vehicle remains operational during the winter months.
While it is essential to treat diesel fuel with an anti-gel in cold climates, it is also important to note that you can purchase winter blend diesel fuel, which may already include anti-gelling agents. However, it can be challenging to determine whether the fuel from the pump has been treated for winter. One way to test this is to fill a mason jar with fuel and set it out overnight or place it in a freezer. If the fuel clouds or gels, it has not been treated, and you should consider adding an anti-gel additive.
In conclusion, anti-gel is indeed essential in cold climates to maintain the health and functionality of diesel engines. By treating diesel fuel with an anti-gel additive, such as Howes Diesel Treat, you can prevent gelling and ensure smooth engine performance, even in freezing temperatures. While it may be challenging to determine if your diesel fuel is already treated, taking proactive measures by adding anti-gel can save you from potential engine issues and costly repairs down the line.

Untreated diesel may cause engine issues in cold weather
Diesel fuel is prone to gelling in cold weather, which can cause engine issues. Gelling occurs when the temperature drops, and the fuel begins to cloud before freezing. This cloudiness indicates that waxy paraffins are coming out of the fuel, and if the fuel gels, it can result in smoke, loss of power, hard starts, or the inability to start the engine at all.
Untreated diesel in cold weather may therefore cause engine issues. Diesel fuel needs to be treated with an anti-gel agent to prevent gelling. This is especially important in areas with consistently cold temperatures, as well as when travelling between warm and cold climates. Without proper care, an engine will not last as long, and the vehicle may suffer from unwanted downtime and lost revenue.
There are various products available to treat diesel fuel, such as Howes Diesel Treat, which is a trusted anti-gel and fuel conditioner. It is designed to work in the coldest climates and is safe to use due to its petroleum-based, alcohol-free formula. Other options include Power Service, K-1, and straight #1. These treatments can be added directly to the fuel tank or at the depot when fuel is picked up for delivery.
While it is possible to over-treat diesel fuel with anti-gel, it is generally not harmful. However, it may cause issues such as hard starting and loss of power. If you are unsure whether your fuel has already been treated, it is recommended to test it by filling a mason jar with fuel and setting it out overnight to observe any clouding or gelling.

Anti-gel is unnecessary in warmer climates
Diesel fuel is usually treated for the average temperature of the area. Therefore, in warmer climates, diesel fuel is unlikely to require additional anti-gel treatment.
Untreated diesel fuel is at risk of gelling when temperatures drop to around 15°F (-9.4°C) or lower. This can result in smoke, loss of power, hard starts, or the inability to start the engine. In such cases, anti-gel additives are essential to prevent gelling and maintain engine performance.
However, in warmer climates, the risk of gelling is significantly reduced. For example, in Texas, the risk of gelling is lower compared to colder regions like the Dakotas in the United States. Similarly, in Arizona, diesel fuel can typically withstand temperatures down to around 10°F (-12°C) without gelling.
While some sources suggest that anti-gel additives are unnecessary in warmer climates, others recommend their use as a preventive measure, especially when travelling between warm and cold climates. Over-treating diesel fuel with anti-gel is generally not harmful, and some products, like Howes Diesel Treat, claim to be safe for over-treatment.
In summary, while anti-gel additives are crucial in colder climates to prevent diesel fuel gelling, they are generally unnecessary in consistently warmer regions. However, it is essential to be aware of any temperature fluctuations and take appropriate measures to protect your engine.
