Refined Fuels

Whether filling your farm equipment with Cenex premium ag diesel fuels from your on-farm tank, or your car with Cenex® TOP TIER™ Detergent Gasoline at one of our convenience stores, United Cooperative offers premium Cenex fuels and lubricants to power your large and small vehicles.

Cenex Premium Diesel Fuels
Want a more efficient fleet? Put a better diesel fuel in the tank.

Now is the perfect time to make the switch to Cenex® Premium Diesel Fuels. They’ve been enhanced to support today’s diesel equipment technologies and ensure consistent performance in all engines, both on and off the road. Newer engines operate under high temperatures and pressures that can literally “cook” typical #2 diesel, resulting in fouled fuel that can damage engine parts.

Cenex Premium Diesel Fuels help prevent these problems. Plus, they’re formulated to optimize performance with a complete, quality, balanced additive package that:

  • Improves fuel economy by as much as 5 percent*
  • Increases power by up to 4.5 percent*
  • Boosts fuel lubricity 10-15 percent*
  • Lowers maintenance costs*
  • Extends life of injectors/injector pumps*
  • Has a typical cetane number of 48

    *Versus typical #2 diesel fuel

Cenex® TOP TIER™ Detergent Gasoline
There are more than 235 million cars and trucks on the road in the United States, and we count on them to get us where we need to go every day. As consumers, we expect our vehicles to last longer too – the average age of a car on America’s roads is 11.4 years, and rising. That’s up from 9.8 years in 2002. Maintaining vehicles takes a lot of time and effort, but Cenex® is making it a little bit easier for you. With Cenex® TOP TIER™ Detergent Gasoline, every fill-up is like a tune-up*: helping clean the engine, controlling buildup and protecting against deposits. See our Q&A for more information. 

United Cooperative's fuel supplier is CHS, a regional cooperative based at St. Paul, Minn., parent company of the Cenex brand of fuel products. CHS recently made the investment to upgrade all Cenex gasolines to meet TOP TIER performance specifications. This investment brings the enhanced fuels to all Cenex branded retail locations. What benefit does Cenex TOP TIER Detergent Gasoline offer you as a consumer?
