Winter can pose significant challenges for diesel engines—particularly due to the risk of diesel fuel gelling in cold temperatures. Unlike gasoline, diesel fuel contains paraffin wax, which solidifies as temperatures drop. This can lead to blockages that hinder fuel flow and impair engine performance. It sometimes causes trucks to completely stall, resulting in costly downtime and repairs. Fortunately, antigel for diesel fuel are specially formulated to combat this issue. Understanding the mechanics of antigel additives and their application can help you protect your fleet from winter-related disruptions.
To determine whether you need antigel for diesel fuel, you should consider temperature forecasts and averages across the regions in which your fleet operates. Low temperature ranges can leave your trucks susceptible to gelling, which starts when the paraffin wax in diesel fuel solidifies. This usually occurs at temperatures between 32°F and 15°F, depending on the diesel blend.
Keep in mind that diesel fuel doesn't freeze in the same way water does. Instead, when fuel gels, wax crystals form and accumulate on the fuel filter. This eventually blocks the flow of fuel and prevents it from reaching the engine. This point is known as the Cold Filter Plugging Point (CFPP), where the fuel becomes too thick to pass through the filter. If left untreated, gelling can cause the engine to shut down, potentially leaving drivers stranded in cold weather.
If 32-degree temperatures are in the forecast, it’s time to use a cold weather additive for diesel fuel to prevent gelling. These products work by modifying the formation of wax crystals in the fuel, keeping them small and less likely to cause blockages. Let’s walk through some of the specific benefits of using antigel additives.
By preventing gelling, antigel additives help maintain consistent fuel flow. This consistency reduces strain and improves efficiency of the engine, prolonging its lifespan.
Trucks perform better in cold weather when fuel flow is uninterrupted. This ensures that operations can continue smoothly, even in sub-zero temperatures.
Gelling can lead to fuel system damage and engine failure, both of which are expensive to repair. Using a cold weather additive for diesel fuel minimizes these risks and saves money in the long run.
Diesel engines rely on compression to ignite the fuel, and colder temperatures make this process more difficult. By maintaining the fuel’s fluidity, antigel additives reduce strain on the battery and starter motor, preventing the need for multiple attempts to start the engine.
With the right antigel for diesel fuel, you can avoid winter-related engine issues—ensuring your fleet remains operational regardless of the weather.
It’s wise to stock both preventative and emergency antigel for diesel fuel. Investing in these products is more cost-effective than the alternative: a breakdown and delay in services. Keller-Heartt Oil offers industry-leading products from Power Service.
Diesel Fuel Supplement +Cetane Boost is a preventative antigel additive designed for use during the cold winter months. By modifying the shape and size of wax crystals, this product prevents them from forming large blockages that disrupt fuel flow.
Here's what else makes it effective:
Diesel 911 is an emergency antigel additive used when fuel has already gelled. It’s designed to effectively break down gelled fuel, quickly restore fuel flow, and get your engines running again. For all-around protection, you can use Diesel 911 and Diesel Fuel Supplement +Cetane Boost at the same time—addressing your current emergency and preparing for the future.

Choosing the right antigel additive is crucial for effective winter diesel fuel management. When evaluating your options, the first thing to consider is the product effectiveness. You need an antigel that can handle the temperature extremes typical of your region. Look for products that have been tested and proven to work in sub-zero conditions.
Another important factor is the reliability of your supplier. You should source your antigel for diesel fuel from a trustworthy supplier who offers consistent quality, reliable and timely customer support, expert product guidance, premium oils for cold weather, and a wide range of other products that meet industry standards. Additionally, it’s wise to choose a supplier who offers both preventative and emergency products. Having access to both types of additives ensures that you’re prepared for any scenario. Keller-Heartt Oil is a full-service leader in the oil and lubricant industry, with 80+ years of experience partnering with fleets like yours.
Compatibility is another crucial consideration. Before purchasing an antigel additive, make sure it is compatible with your specific type of diesel fuel and engine. Different fuel formulations, such as Ultra Low Sulfur Diesel (ULSD) or biodiesel blends, may require specific additives. Ensuring compatibility helps prevent damage to your fuel system and guarantees the additive will work as intended without causing any negative effects.
Finally, consider whether the antigel contains lubricators. Additives that include lubricators, like Slickdiesel, can help maintain your fuel system—reducing wear on essential components such as fuel pumps and injectors. This is especially important with ULSD fuel, which can increase wear due to its lower sulfur content. An additive with a lubricator will help keep your engine components running smoothly and protect against premature wear.
