The premium cold-weather diesel fuels you need to face down winter

Cenex® winterized premium diesel fuels keep your equipment running strong as temperatures plunge. Our cold-weather premium diesel fuel additives work as hard as you do, with enhanced low-temperature operability and minimal filter plugging to ensure reliable engine and fuel system performance.

  • Wax crystal modifiers – Alter wax crystal structures to prevent gelling and blockages, allowing fuel to pass through fuel filters efficiently.
  • Wax anti-settling agents – Keep wax crystals suspended and dispersed within the fuel, ensuring its smooth flow and minimizing the risk of clogging.
  • De-icers – Dramatically reduce the freezing point should any water be present in the fuel system.

Better than any winterized fuels that have come before

Cenex premium diesel fuels for cold weather deliver the ultimate protection against engine and fuel system issues common in frigid temperatures.
  • Aggressive detergency package
    Keep engines running cleaner, longer with an aggressive detergency package that gives you optimal engine performance and efficient combustion—better than any formula that’s come before.
  • Total water management system
    The two-phase system efficiently separates free water from fuel, allowing it to settle quickly at the bottom of fuel storage tanks for easy drainage and removal. Any remaining negligible water is encapsulated for safe passage through the combustion chamber, ensuring your fuel system runs smoothly and efficiently.
  • A more complete fuel burn1
    With lower temperature fluctuations, more complete combustion is managed evenly across the entire engine. That’s because ultra-clean injectors share the work. As a result of this improved efficiency, less soot is produced and fewer regenerations occur—and that means less wear and tear on the exhaust system.
  • Exceptional filterability
    Keep equipment running smoother, longer with exceptional filterability that protects the engine and exhaust aftertreatment systems.
