Diesel fuel supplements are additives that improve the performance of diesel engines. They are particularly useful in cold weather, when diesel fuel can transform into a waxy, gel-like substance that restricts fuel flow and causes engine issues. Diesel fuel supplements prevent this by acting as an anti-gel, and they can also help to clear built-up gel in fuel lines and filters. In addition to anti-gel additives, there are also fuel stabilizers, which prevent fuel from degrading and becoming unusable over time. Other benefits of diesel fuel supplements include improved fuel economy, lubrication, and reduced emissions output.

What You'll Learn
Using anti-gel additives in winter
Diesel fuel tends to transform into a waxy, glue-like gel in extreme cold conditions, which can restrict fuel flow and cause severe damage. This is why anti-gel additives are essential during the winter months.
How Anti-Gel Additives Work
Anti-gel additives contain a combination of a wax modifier, a wax anti-settling agent, and a de-icer, which work together to prevent fuel gelling and protect against fuel-filter icing. The wax modifier reduces the temperature at which the wax in diesel fuel solidifies, while the wax anti-settling agent keeps the wax dispersed. The de-icer prevents clogging and freezing of fuel filters by dispersing moisture.
When to Use Anti-Gel Additives
It is recommended to use anti-gel additives whenever you fill up your diesel tank during the winter to ensure proper mixing and maximize their effectiveness. In areas with consistently cold temperatures, using an additive with an anti-gelling agent is crucial for the health of your engine.
Benefits of Anti-Gel Additives
Anti-gel additives not only prevent fuel gelling and improve cold starts, but they also boost cetane numbers, improving fuel combustion and overall engine performance. Additionally, they act as lubricants, protecting fuel pumps and injectors from wear and tear, thereby extending the life of your diesel engine.
Popular Anti-Gel Additive Options
Some popular anti-gel additive options include Diesel Winter Anti-Gel by Hot Shot's Secret, Diesel Fuel Supplement +Cetane Boost by Power Service, and Diesel Treat by Howes Products. These products are safe for use in a wide range of diesel engines and are designed to improve winter operability.

Improving combustion with cetane boosters
Cetane boosters, also known as cetane improvers, are diesel fuel additives that improve the quality of combustion. They do this by boosting the cetane number of the fuel blend when added in low concentrations. The cetane number is an indicator of the combustion speed for the fuel and compression that's necessary for ignition.
A higher cetane number allows fuel to burn for longer, which in turn increases the pressure within the combustion chamber, leading to minimal noise and less engine knock. This also results in improved fuel efficiency, as it increases the potential for every droplet sprayed into the combustion chamber to produce more power. This means you will get more miles per gallon of fuel, and spend less on fuel.
Cetane boosters also support smoother, faster combustion, which leads to fewer smoke emissions. They also give diesel engines a great cold start by sparking up the ignition and enhancing their responsiveness.
However, it is important to note that not all experts agree on the benefits of cetane boosters. Some sources claim that the negative effects of cetane boosters far outweigh the benefits, and that the majority of engine manufacturers do not recommend using them. Additionally, if the cetane number is increased too high (55 and beyond), it can deteriorate the fuel and cause a reduction in overall engine performance. Therefore, it is important to exercise caution and do your research before using cetane boosters.

Adding lubricants to protect engine parts
Diesel fuel supplements are used to improve the performance of diesel engines. They can be used to address specific issues, such as improving ignition speed and preventing fuel gelling in cold weather.
One of the key benefits of diesel fuel supplements is their ability to act as lubricants, protecting fuel system components like pumps and injectors from premature deterioration. This added lubricity can extend the life and increase the performance of diesel engines.
For example, Howes Diesel Treat is a popular anti-gel diesel fuel conditioner that provides added lubricity to injectors, pumps, and upper cylinders. It helps to prevent carbon deposits and fuel injector deposits, improving performance and fuel economy.
Opti-Lube XPD is another top-rated diesel fuel additive that enhances lubricity, boosts cetane, and cleans injectors. It also includes an anti-gel to keep fuel flowing down to -10°F, making it ideal for everyday use.
When choosing a diesel fuel supplement, it is important to consider the specific needs of your engine and the climate conditions it will be operating in. Some supplements are designed specifically for cold weather, while others are suitable for all seasons. Additionally, some supplements may be more effective for certain types of diesel engines, so it is recommended to consult with a professional or refer to manufacturer guidelines for specific recommendations.
By adding lubricants to diesel fuel, engine parts are protected from wear and tear, helping to maintain optimal performance and prolong the life of the engine.

Cleaning injectors and fuel systems
Keeping your fuel system clean is essential. Fuel injectors play a critical role in your engine's performance, and keeping them clean can save you money on fuel, prevent costly repairs, and extend the life of your engine.
There are several ways to clean your injectors and fuel systems. One way is to use a diesel injector cleaning product, which can help prevent and eliminate algae buildup, keeping your fuel system clean. These products also contribute to maintaining lubricity in diesel fuel, which prevents wear and tear on engine components. When using a diesel injector cleaning solution, simply add the recommended amount to your fuel tank before filling up with diesel.
Another way to clean your injectors is to use a high percentage of biodiesel for a few tanks. Biodiesel will clean up the inside of the fuel system and leave any junk from your tank in the filter. However, it is important to keep an extra fuel filter on hand when using this method.
There are also several fuel injector cleaning products on the market that can help keep your fuel system clean. These products work by flowing through your fuel system, cleaning the fuel injectors and other components. Some products are designed to clean the entire fuel system, making them ideal for older, carbureted cars, as well as devices that use internal combustion, such as lawnmowers, motorboats, and motorcycles. These products are also suitable for gasoline-hybrid vehicles.
It is also worth noting that some people recommend using fuel additives as a preventative measure to keep your fuel system clean. However, others argue that additives may do more harm than good, as you cannot know how they will affect the lubricity of the fuel.
In addition to these methods, some people suggest that the best way to clean injectors is to hook up a heavy trailer, get the truck up to highway speeds, and keep the pyrometers above 1,000 degrees Fahrenheit to burn off any tar and carbon.
By using these methods and products, you can effectively clean your injectors and fuel systems, leading to improved engine performance and longevity.

Stabilising fuel for long-term storage
Diesel fuel can be stored for a long time, but several factors influence how long it lasts. The fuel's stability and longevity are affected by its environment, the type of fuel, and the use of additives.
Firstly, the storage environment is crucial. Diesel fuel should be kept away from direct sunlight and extreme temperatures. The ideal temperature range for storage is between 32° and 95° Fahrenheit. Keeping the fuel cool and dry is essential, as temperature fluctuations can cause the fuel to degrade faster. Additionally, it is recommended to minimise the amount of space left in the tank to reduce condensation and water buildup from condensation.
Secondly, the type of diesel fuel matters. Conventional diesel fuel is generally more stable and has a longer shelf life than biodiesel or biodiesel blends. Biodiesel tends to be more sensitive to temperature and oxygen exposure, making it less suitable for long-term storage.
Lastly, using fuel additives and stabilisers can significantly improve the longevity of diesel fuel. Fuel stabilisers help prevent the fuel from degrading and becoming unusable. Biocides, such as Biobor JF, are essential for killing microbial contamination, which is more likely to occur due to the removal of sulfur from Ultra Low Sulfur Diesel (ULSD). Diesel Fuel Supplement +Cetane Boost is another additive that can be used during cold winter months to prevent fuel gelling and keep fuel filters from plugging with ice and wax. Other additives, such as Hot Shots, Diesel Extreme, and Diesel Kleen, can also improve fuel performance, lubrication, and stability.
By following these guidelines and choosing the appropriate additives, diesel fuel can be effectively preserved for long-term storage.
