Winterized Premium Diesel Fuels Fueled by Innovation. Powered to Perform.™ WINTER CAN BE TOUGH, BUT CHOOSING YOUR FUEL SHOULDN’T BE. What You Need to Face the Cold. Get ready to tackle winter weather with Cenex® winterized premium diesel fuels. You can count on us to keep your equipment running strong in even the coldest conditions. Our cold weather additives are designed to work as hard as you do, with enhanced low temperature operability, minimized filter plugging, and ensuring reliable engine and fuel system performance. Wax crystal modifiers Reduce downtime and significantly increase cold weather operability by changing the shape and size of wax crystal structures, which allows them to pass through fuel filters and prevent blocking while the engine heats up. De-icers Dramatically reduce the freezing point of any water present in the fuel system, resulting in a significant decrease in issues caused by moisture. Wax anti-settling agents Enhance the operability of equipment in cold/winter weather and reduce both downtime and maintenance costs. Prevent wax crystals from settling in equipment and causing clogs in your fuel system’s filters and other engine components. Cenex winterized premium diesel fuels deliver the ultimate protection against cold-weather related engine issues. With our fuels, you can drive with confidence all season long.

Cenex is one of the only fuel distributors to have a robust network for distributing a terminally injected diesel fuel product. By injecting fuels at the terminal, Cenex ensures optimal additive concentration levels within the diesel fuel. Unlike splash-blended aftermarket additives. Cenex can adjust blending rates to match the ideal proportion of additives, as per the characteristics of the base fuel, allowing for optimal engine performance.

REDUCES EXHAUST TEMPERATURE DEVIATIONS by 25%1 SUPERIOR CHEMISTRY FOR SUPERIOR PERFORMANCE AGGRESSIVE DETERGENCY PACKAGE Clean the entire fuel system for better cold weather operation. Our process has been shown to be 40% more effective in breaking down detrimental engine deposits1 and 2.5 times more effective at removing injector build-up1. When faced with extreme cold, a clean fuel system can offer up to 4.5% more power2 and up to 5% better fuel economy2. TOTAL WATER MANAGEMENT SYSTEM Keep moisture from entering the fuel system, even at icy winter temperatures. Even in extremely cold conditions, our system efficiently separates water from the fuel, allowing it to settle at the bottom of the tank for easy drainage. Even if there is a small amount of remaining negligible water, it is safely carried through the combustion chamber. INJECTION & COMBUSTION OPTIMIZATION Ensure cold weather doesn’t slow you down by addressing fuel oxidation problems in new engine technology. In frigid winter conditions, this product protects diesel fuel from coking, curtails the need for frequent filter and injector repairs, and stops the formation of internal diesel injector deposits in finely-tuned injectors. STORAGE STABILITY Extend storage life during winter months 3 to 6 times longer than typical #2 diesel. Stores well in extremely low temperatures. Prevents accumulation of gum and varnish and enhances injector lifespan while maximizing combustion efficiency. CORROSION PROTECTION Protect ice cold fuel lines from rust and corrosion. In harsh winter climates, our fuel serves to hinder the formation of rust and corrosion on metallic components, safeguards fuel systems against rust and pitting, stops the development of leaks, blockages, and fractures stemming from corrosion, and decelerates the natural deterioration of diesel fuel resulting from contact with oxygen. IMPROVED LUBRICITY When the temperature drops, protect moving parts from excessive wear and failure. In wintry conditions, our solution boosts lubricity by 10% to 15%2, wards off wear on injectors and fuel pumps, and fulfills the fuel lubricity specifications recommended by OEMs. HIGH CETANE NUMBER Enhance ignition quality for quicker, smoother starts during winter’s coldest temps. In tough winter conditions, our fuel produces lower emissions and maintains diesel particulate filters for longer periods of time. It also reduces the frequency of regenerations required and minimizes strain on the vehicle’s starter and battery. On top of that, it enhances the ability to start in cold weather. 1 In comparison to the previous generation of Cenex® premium diesel fuel 2 In comparison to typical #2 diesel PREMIUM DIESEL FUEL AVAILABLE WHEN AND WHERE YOU NEED IT Cenex is one of the only fuel distributors with a robust network for distributing terminally injected diesel fuel products: Available for purchase at 625+ Cenex retail locations Available through 400+ regional fuel distributors Cenex serves a wide network of distributors across 19 states FUEL UP TODAY Locate your nearest Cenex Premium Diesel Fuels dealer.
