Do You Really Need Winter Additives

Although winter may still feel far off, preparing diesel fuel systems early is essential to avoid problems when freezing temperatures arrive. Cold weather brings unique challenges for diesel, as paraffin wax inside the fuel begins to crystallize, leading to clogged filters, restricted flow, and even engine shutdowns. By getting ready ahead of time with a winter fuel additive program, you can ensure reliable performance and avoid costly disruptions once the cold sets in.

Winter fuel additives are treatments blended into diesel fuel to help it perform better in cold weather. These formulas typically contain detergents, cold flow improvers, lubricants, and de-icers. Together, these components lower the fuel's Cold Filter Plugging Point (CFPP) and pour point, preventing wax crystals from blocking filters. In addition to protecting against gelling, additives can also clean and protect the fuel system, improve cold starts, and reduce harmful deposits.

Do You Really Need It?

The short answer is yes. If you operate in regions where winter temperatures dip near or below freezing, winter fuel additives are a must. Even a single night of subfreezing weather can be enough to gel untreated diesel, leaving equipment stranded and businesses facing costly downtime. While some fuel suppliers pre-treat their diesel, coverage isn't guaranteed across all regions or stations.

When diesel is exposed to freezing conditions, paraffin wax molecules begin to cluster, forming crystals that restrict the flow of fuel. At around 15°F, the wax starts thickening. As the temperature continues to drop, untreated diesel will begin to form large gel chunks, preventing fuel from passing through filters. Winter fuel additives chemically alter the wax structure, keeping it small and dispersed so that fuel continues to flow freely. Many formulas also address water content in the fuel, preventing ice from forming in filters and lines.

When to Use It

Timing is key when it comes to fuel protection. Additives should be introduced before temperatures drop below freezing so they can blend thoroughly with the fuel. As a rule of thumb, treating diesel anytime freezing conditions are expected ensures complete protection. For equipment or vehicles that may sit idle for days or weeks, treating fuel proactively is especially important to prevent gelling when operations resume.

Choosing the Right Treatment

Not all additives perform the same, so it is important to select a product designed specifically for diesel winterization, such as Mansfield's Arsernal ColdPro.

Arsenal ColdPRO is a high-performance winter diesel additive formulated to provide fuel operability down to -20°F when properly blended, while also providing power boost, detergency, and lubricity.

As you can see, winter fuel additives are more than just a precaution; they are a necessity for anyone relying on diesel during cold months. By keeping fuel flowing and engines running smoothly, they protect both equipment and budgets from costly breakdowns.

Plan Ahead and Reduce Costs

Just as planning your fleet's routes is crucial for efficiency, properly preparing your fuel for winter is essential for avoiding costly breakdowns. Mansfield's Arsenal ColdPRO is a program to improve your fuel's cold-weather performance, offering consistent and accurate treatments, minimizing kerosene cost, and performing nationwide fuel testing.

With the right strategy in place, you can keep your fleet running smoothly throughout the winter season, regardless of where you operate.
