Diesel fuel is known to thicken or gel in cold temperatures, which can cause significant issues for diesel engines. This occurs when the wax within the fuel thickens and solidifies, clogging fuel lines and filters. To prevent this, diesel anti-gel additives are available, which lower the temperature at which the fuel gels and improve overall performance. Diesel anti-gel is recommended for use in all diesel engines during the winter months, especially in colder climates.

What You'll Learn
Anti-gel additives prevent clogging
Diesel fuel does not perform well in cold weather. When temperatures drop, the wax in diesel fuel solidifies, forming crystals that clog fuel filters and fuel lines. This can cause engines not to start and may lead to costly repairs if the engine becomes damaged.
Anti-gel additives are designed to prevent this issue by lowering the temperature at which the wax in diesel fuel solidifies. This is known as the Cold Filter Plugging Point (CFPP). By lowering the CFPP, anti-gel additives prevent the wax from crystallising and clogging fuel filters and lines.
Products such as Hot Shot's Secret Diesel Winter Anti-Gel contain a wax modifier that significantly reduces the point at which wax in diesel fuel solidifies. This prevents the wax from sticking together and clogging lines and filters in the fuel system. Diesel Winter Anti-Gel also contains a powerful cetane improver for quicker cold starts and a maximum boost in power and performance.
Anti-gel additives are easy to use – they can be added before or after fuelling up, and they won't damage your engine. It's recommended to start using anti-gel additives when temperatures drop below freezing (32°F or 0°C).

Add anti-gel when temperatures are below freezing
Diesel fuel contains wax, which is liquid at normal temperatures. However, as temperatures drop, the wax crystallises, solidifies, and sticks together. These wax crystals can clog fuel lines and filters, causing issues for diesel engines. This process is known as diesel fuel gelling, and it is a common problem in colder climates.
To prevent diesel fuel gelling, it is essential to add an anti-gel additive when temperatures are below freezing (32°F or 0°C). Anti-gel additives work by lowering the cold filter plugging point (CFPP) of diesel fuel, preventing wax crystals from forming and clogging the fuel system. They also improve the quality of standard diesel fuel in terms of detergency, stability, lubricity, and winter operability.
It is recommended to use anti-gel additives each time you fill your fuel tank to ensure proper mixing and maximise the effectiveness of the additive. The amount of additive required will depend on the temperature, with more additive needed at lower temperatures. It is important to follow the instructions on the bottle of your chosen anti-gel product.
There are several high-quality anti-gel additives available on the market, such as Hot Shot's Secret Diesel Winter Anti-Gel, Fuel Ox Cold Charge, and Howes Diesel Treatment. These products can effectively prevent diesel fuel gelling and improve the performance of your vehicle during the cold winter months.

Anti-gel improves diesel fuel quality
Diesel fuel has several advantages, including greater vehicular power and fuel economy. However, one of its main drawbacks is its poor performance in cold weather. When temperatures drop, diesel can form crystals that clog fuel filters and lines, leading to fuel gelling. This is where anti-gel additives come in.
Anti-gel additives are designed to improve the quality of diesel fuel and enhance its performance during winter. They achieve this by lowering the cold filter plugging point (CFPP) of the diesel fuel, preventing clogged fuel filters and lines. This is a significant advantage as it helps to avoid the issues that can arise when diesel turns into a gel-like substance at lower temperatures, such as restricted flow.
One notable benefit of anti-gel additives is their ability to improve the detergency, stability, lubricity, and winter operability of diesel fuel. By increasing the lubricity of wax molecules within the fuel, anti-gel additives prevent the formation of wax crystals that can clog fuel systems. This, in turn, improves the overall performance of diesel engines, ensuring smoother operation even in cold conditions.
Furthermore, anti-gel additives can boost the cetane number of diesel fuel, leading to quicker cold starts and improved power and performance. This is especially beneficial for diesel engines operating in cold climates, as it enhances their reliability and efficiency during winter.
In addition to their performance benefits, anti-gel additives also address other fuel-related issues. They can help with fuel stabilization, icing, sludge buildup, water contamination, microbial growth, and corrosion. By preventing fuel oxidation, anti-gel additives maintain the stability of bio-blends, safeguarding against seal failure and internal component clogging.
Overall, anti-gel additives are a valuable solution for improving the quality and performance of diesel fuel during winter. By preventing fuel gelling and addressing various fuel-related issues, anti-gel additives ensure the smooth and efficient operation of diesel engines, even in cold weather conditions.

Anti-gel additive preparation
Diesel fuel contains wax in suspension, which is liquid at normal temperatures. However, as temperatures drop, these wax crystals solidify and stick together, clogging fuel lines and filters, causing issues for diesel engines. This is why diesel fuel is known to not fare well in cold weather.
Anti-gel additives are a solution to this problem. They work by lowering the cloud point of the fuel, increasing the lubricity of the wax molecules within the fuel, and preventing them from sticking together. This, in turn, prevents the wax from clogging lines and filters in the fuel system.
Anti-gel additives are recommended to be used each time you fill your fuel tank to ensure proper mixing with your diesel fuel and to maximize effectiveness at preventing clogged fuel filters. It is also suggested that you start using anti-gel additives as soon as temperatures approach freezing. The lower the temperature, the more fuel additive needs to be added.
Hot Shot's Secret Diesel Winter Anti-Gel is one such additive that improves cold temperature performance. It contains a powerful cetane improver for quicker cold starts and a maximum boost in power and performance. It should be used in every fill-up during the cold winter months, with recommended treatment rates of 1:1000 for #2 diesel.
Another option is Fuel Ox™ Cold Charge, which is a preventative measure against fuel gelling. For already gelled fuel, they suggest using their emergency fuel treatment, Fuel Ox™ Heat Bomb, to restore the flow of frozen fuel lines.

Anti-gel treatment for gelled fuel
Diesel fuel is known to not perform well in cold weather. When temperatures drop, diesel forms crystals that clog fuel filters and fuel lines, which can cause significant engine issues. This is where anti-gel treatments come in.
Anti-gel additives are designed to prevent diesel fuel from gelling in cold weather. They work by lowering the cold filter plugging point (CFPP) of the diesel fuel, which prevents wax crystals from forming and sticking together, thereby avoiding clogged fuel lines. Anti-gel treatments also improve the quality of standard diesel fuels in detergency, stability, lubricity, and winter operability.
There are several anti-gel treatments available on the market, such as Hot Shot's Secret Diesel Winter Anti-Gel, Howes Diesel Treat, and Fuel Ox™ products. These treatments are safe to use in all diesel engines, including semi-trucks, pick-up trucks, farm equipment, and standard-sized automotive vehicles. It is recommended to use anti-gel treatments each time you fill your fuel tank to ensure proper mixing and maximize effectiveness.
If your diesel fuel has already gelled, you can use an emergency fuel treatment product like Fuel Ox™ Heat Bomb, which is designed to restore the flow of frozen fuel lines. It is important to follow the instructions on the product's bottle and take necessary precautions when handling such chemicals.
In addition to anti-gel treatments, there are some general precautions you can take to prevent diesel fuel from gelling. Firstly, try to avoid rapid drops in temperature by preparing for cold fronts in advance. Secondly, pay attention to the fuel's pour point, which is the lowest temperature at which diesel fuel can be poured. Below this point, the fuel will become too gelled to flow properly.
