Anti-gel additives lower the freezing point of diesel fuel
Diesel fuel contains paraffin, which starts to crystallize at temperatures of 32 °F (about 0 °C). As the temperature continues to drop, the paraffin will turn to gel, clogging the fuel tank and filters. This can cause the engine to stop working altogether and may necessitate costly repairs.
To prevent this, anti-gel additives can be used to lower the freezing point of diesel fuel. Anti-gel additives are easy to use: simply add them to your fuel tank. 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. By lowering the CFPP, anti-gel additives prevent the formation of fuel clumps and ensure fuel can flow freely at low temperatures.
The wax component in diesel fuel is what causes it to gel. While the wax normally exists as a liquid in solution in the fuel, it can form waxy solid crystals at low temperatures, which block engine fuel filters. Anti-gel additives prevent the wax from solidifying, thereby reducing the likelihood of fuel freezing in cold temperatures.
It is recommended to start using anti-gel additives as soon as temperatures approach freezing. The amount of additive required will depend on the temperature: the lower the temperature, the more additive needs to be added. It is also important to prepare for rapid drops in temperature by adding more anti-gel additive in advance.
In addition to anti-gel additives, there are other measures that can be taken to prevent diesel fuel from gelling. Kerosene, for example, has a lower gelling point than diesel fuel and can be mixed with diesel to lower its freezing point. However, this may result in reduced fuel mileage and efficiency. Using a lubricating diesel additive can also help to improve engine performance and protect against wear and tear.

Anti-gel additives are easy to use
Diesel fuel contains paraffin, which starts to crystallize at 32°F (0°C). As the temperature drops further to 11-15°F (-11 to -26°C), the paraffin turns to gel, clogging the fuel tank and filters. This is why diesel engines may not start in cold weather. To prevent this, you can use an anti-gel fuel supplement, which is easy to add to your tank.
The wax in diesel fuel is what causes it to gel. In cold weather, the wax can cause fuel to turn into a gel-like substance, which then blocks the engine fuel filters. Anti-gel additives prevent this from happening. Importantly, anti-gel additives do not damage your engine, so when in doubt, it is recommended to use extra.
There are a variety of anti-gel additives available on the market, such as Fuel Ox™ Cold Charge, which prevents fuel gelling, and Fuel Ox™ Heat Bomb, which is an emergency treatment for already gelled fuel. Howes Diesel Treat is another popular option, providing unbeatable protection for diesel engines in cold weather. These additives are designed to improve the performance of your diesel engine and are safe to use.
In addition to anti-gel additives, there are other types of additives that can be beneficial for diesel engines. Lubricating additives, for example, can increase lubrication and prevent corrosion, reducing engine wear and tear. There are also anti-foam additives, which reduce surface tension and prevent fuel-cut off, keeping your fuel management system clean.

Diesel fuel anti-gel should be used when filling the tank in winter
Diesel fuel contains paraffin, which starts to crystallize at 32°F (0°C). As the temperature drops further to 11-15°F (-11 to -26°C), the paraffin turns to gel, clogging the fuel tank and filters. This can cause the engine to gel up completely and stop working.
To prevent this, diesel fuel anti-gel should be used when filling the tank in winter. Anti-gel additives lower the freezing point of diesel fuel, making it less likely to freeze in cold temperatures. They also lower the Cold Filter Plugging Point (CFPP), which is the lowest temperature at which fuel will flow through a specific filter.
It is recommended to start using anti-gel additives as soon as temperatures approach freezing. The amount of additive required depends on the temperature, with more being needed at lower temperatures. Anti-gel additives can also be used in preparation for an anticipated cold snap.
In addition to preventing fuel gelling, anti-gel additives can improve engine performance in cold weather and reduce fuel consumption. They increase fuel efficiency, improve lubricity, and reduce the quantity of soot and particulate matter produced during combustion.

Kerosene can be mixed with diesel fuel to lower the freezing point
Diesel fuel contains paraffin, which starts to crystallize at 32 °F (about 0 °C). When the temperature drops further to 11-15 °F, the paraffin turns to gel, clogging the fuel tank and filters. This can cause the engine to stop working. To prevent this, anti-gel additives are used, which lower the freezing point of diesel fuel.
Kerosene, also known as paraffin, is a combustible hydrocarbon liquid derived from petroleum. It is used as a fuel in aviation, households, and some vehicles. Kerosene has a freezing point of around -40 °C (-40 °F) to -47 °C (-53 °F), depending on the grade. Mixing kerosene with diesel fuel can lower the freezing point of diesel, reducing the likelihood of fuel gelling and improving engine performance in cold weather.
Kerosene is produced by fractional distillation of crude oil in an oil refinery. Its distillation process removes volatile hydrocarbon fractions, resulting in a clear and safe-to-burn product. While kerosene is a polluting fuel with associated health risks, it is still widely used in developing countries for lighting, cooking, and powering small motors.
When using kerosene as a diesel additive, it is important to consider the potential for water contamination, which can cause freezing and clogging issues. Additionally, the use of fuel additives designed for diesel fuel may be more effective in improving engine performance and fuel efficiency.
In summary, kerosene can be mixed with diesel fuel to lower its freezing point, but it is essential to monitor for water contamination and consider using specialized diesel additives for optimal engine performance.

Anti-gel additives are a cost-effective solution
Diesel fuel contains paraffin, which starts to crystallize when temperatures drop to 32°F. As the temperature continues to drop, the paraffin will eventually turn into a gel, clogging the fuel tank and filters. This process is known as diesel gelling, and it can cause significant issues for diesel engines.
To prevent diesel gelling and improve cold-weather performance, anti-gel additives are a cost-effective solution. These additives work by lowering the freezing point of diesel fuel, making it less likely to gel in cold temperatures. By reducing the Cold Filter Plugging Point (CFPP), anti-gel additives ensure that fuel can still flow through the filters even in low temperatures. This is particularly important as diesel fuel contains wax, which is the main cause of gelling.
There are several anti-gel additive products available on the market that are designed to prevent gelling and improve engine performance.
