The next generation of premium on-road diesel fuel

Cenex Roadmaster XL® is precisely formulated with a superior additive package to deliver the power and performance you need to go the distance, even in the toughest conditions. 

An industry-leading premium diesel additive package enhanced with: 

  • Advanced, aggressive detergency that effectively removes engine deposits and keeps injectors clean, extending engine life span 
  • A state-of-the-art, two-phase total water management system that optimizes combustion and boosts engine function 
  • Exceptional filterability that protects equipment from harmful contaminants, minimizing equipment damage and operational disruptions 
  • A complete fuel burn that minimizes waste and improves overall fuel efficiency, delivering more miles per gallon

Better than any on-road premium diesel formula that has come before

Improve power and fuel efficiency with a more complete fuel burn. 
  • 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.
