Diesel fuel additives are chemical substances added to improve specific properties or maintain quality. They can be added at the refinery, in the fuel distribution system, or by the end-user. The two basic categories of additives are fuel stabilizers and fuel performance enhancers. Fuel stabilizers ensure diesel remains functional and effective over time by preventing it from breaking down during storage and inhibiting the separation of gas and water, which can cause engine corrosion. Fuel performance enhancers maximize fuel efficiency, improve fuel economy, and boost engine performance by lubricating and cleaning the fuel system. Additives also help address drivability issues caused by the nature of diesel fuel, such as the formation of wax-like substances in cold weather, which can block fuel flow.

Anti-gel additives
Diesel fuel stabilizers are essential in maintaining the quality and efficiency of diesel fuel, especially when it is stored for extended periods. These stabilizers prevent fuel degradation, oxidation, and microbial growth, ensuring that the fuel remains stable and fresh.
One such stabilizer is the STA-BIL Diesel Fuel Stabilizer, which is designed for all diesel engines and fuels. It prevents sludge and sediment formation, cleans and lubricates fuel injectors, and helps remove water to inhibit microbial growth. This stabilizer can keep fuel fresh for up to 12 months and is recommended for use at every fill-up.
While STA-BIL focuses on stabilization, they also offer the STA-BIL Diesel All-Season variant, which provides additional benefits. This product includes an anti-gel additive, providing protection down to -40°C, making it ideal for winter use. It also acts as a full-system cleaner, lubricant, water remover, and cetane booster.
Another trusted anti-gel additive is the Howes Diesel Treat, which is popular in North America. This product is effective in preventing gelling, even in extremely cold climates, without the use of alcohol or harmful solvents. It also acts as a fuel conditioner, providing lubricity, preventing deposits, and improving engine performance.
During winter, Diesel Winter Anti-Gel additives are crucial to prevent fuel line freeze and improve cold starts. These additives use a combination of chemicals, including a wax modifier, a wax anti-settling agent, and a de-icer, to ensure smooth engine operation in freezing temperatures. Diesel Winter Anti-Gel by Hot Shot's Secret is recommended for use in all diesel engines during the winter months, adding detergency, stability, lubricity, and improved cetane numbers.

Raising the cetane number
STA-BIL offers a range of fuel stabilizers and treatments for diesel engines. STA-BIL Diesel Fuel Stabilizer is designed to keep fuel fresh for quick and easy engine starts, and to maximize engine performance. It prevents sludge and sediment formation, and lubricates and cleans fuel injectors. It is safe for use with all diesel engines and fuels, and can treat up to 320 gallons of fuel.
STA-BIL Diesel All-Season is another option, which can be used in conjunction with STA-BIL Diesel Fuel Stabilizer. It provides a full system cleaner, a lubricant, a water remover, and an anti-gel additive. It also boosts cetane. STA-BIL Diesel All-Season is effective in all diesel fuels, including biodiesel, and is B20 compliant.
STA-BIL Storage Fuel Stabilizer is another product that can be used in both ethanol and non-ethanol blended fuels. It keeps fuel fresh for 24 months, prevents corrosion, and protects the fuel system.
In terms of raising the cetane number, STA-BIL Diesel All-Season boosts the cetane number and provides anti-gel protection down to -40°C. Hot Shot's Secret EDT+ Winter Defense is another option for boosting the cetane number. It is a 7-in-1 anti-gel diesel fuel additive that improves cold starts and boosts cetane.

Lubricity additives
Diesel fuel stabilizers are essential in maintaining the quality and efficiency of diesel fuel, especially fuel that has been stored for long periods. STA-BIL, for example, is a diesel fuel stabilizer that prevents sludge and sediment formation, cleans and lubricates fuel injectors, and improves engine performance. It also acts as a water remover, preventing the growth of microbes and algae.
However, the query also mentions Stabill-type additives, which can refer to lubricity additives. Lubricity additives are essential in maintaining vehicle fuel systems and engines. Ultra-Low Sulfur Diesel (ULSD) has been known to cause issues for diesel-powered vehicles due to the removal of sulfur, oxygen, and nitrogen, all of which contribute to the fuel's lubricity. The lack of lubricity can lead to excessive wear and eventual failure of fuel pumps and injectors. Lubricity additives such as Hot Shot's Secret LX4 Lubricity Extreme and Opti-Lube XPD aim to address this issue by returning oxygen to the fuel, enhancing lubricity, and reducing wear on fuel system components. These additives are designed to improve engine performance, fuel efficiency, and protection.
When choosing a lubricity additive, it is important to consider factors such as effectiveness, cost, and environmental impact. Some additives, like Hot Shot's Secret LX4, are designed to be environmentally friendly, while others may vary in terms of performance and price. It is always recommended to consult a professional or refer to reliable sources for guidance in selecting the most suitable additive for specific vehicles and requirements.

Biodiesel blends
Biodiesel is a blend of diesel and biofuel, usually derived from vegetable oils. It can be used in its pure form (B100) or blended with petroleum diesel at any concentration, but most biodiesel is blended with petrodiesel to less than 10% as most engines cannot run on pure biodiesel without modification. The blend percentage of biodiesel is indicated by a "B" factor, so B100 represents pure biodiesel, B20 is 20% biodiesel, and so on.
The most common biodiesel blends are B5 (up to 5% biodiesel) and B20 (6-20% biodiesel). B20 is a common blend because it represents a good balance of cost, emissions reduction, cold-weather performance, and compatibility with conventional engines. B20 and lower-level blends can be used in current engines without modifications, but blends above 20% biodiesel may impact engine warranties and present storage issues.
