Cenex® winterized premium diesel fuels
Fueled by Innovation. Powered to Perform.®
Precisely formulated on-road and off-road winterized premium diesel fuels that ensure optimal power, performance and protection, even in the most unforgiving winter conditions.
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.
Rugged protection all winter long
Cenex winterized premium diesel fuel products are engineered to keep your operation moving throughout the winter months.

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.
1. In comparison to the previous generation of Cenex® premium diesel fuel
Superior chemistry. Superior performance. Even in the coldest temperatures.
Injection and combustion optimization
Addresses fuel oxidation problems in new engine technology
- Prevents diesel fuel from coking
- Reduces critical component and injector repairs and replacements
- Prevents internal diesel injector deposits from forming deep inside high-precision injectors
Storage stability
Extends storage life months longer than typical #2 diesel
- Tolerates storage in extremely low temperatures
- Reduces gum and varnish buildup
- Increases injector life and optimizes combustibility
Corrosion protection
Protects fuel lines from rust and corrosion
- Prevents rust and corrosion from forming on metal parts in icy weather
- Protects fuel systems from rust and pitting from standard cold-weather diesel fuel
- Prevents corrosion-caused leaks, blocking and breaks
- Slows natural diesel fuel degradation caused by exposure to oxygen
Improved lubricity
Defends moving parts against excessive wear and failure
- Provides 10% to 15% more lubricity2
- Protects engine components, injector and fuel pumps against wear
- Meets OEM fuel lubricity recommendations
2. In comparison to typical #2 diesel
High cetane number
Enhances ignition quality for quicker, smoother starts
- Generates fewer emissions for longer-lasting diesel particulate filters
- Fewer regenerations
- Reduces wear and tear on vehicle starter and battery
- Improves cold weather starts
