Refined Fuels

Only the best for farm and fleets

Today’s sophisticated engines require superior fuels to operate most efficiently with minimal downtime. That’s why we’re proud to offer Cenex-brand fuels, which we blend in our fuel plants at Fort Atkinson and Ossian. 

You’ll find we provide unmatched customer service, from our energy salespeople to our professional drivers. Some of our services include:

  • Daily pricing
  • Forward contracting
  • Professional delivery drivers 
  • Monitors available to keep tanks from running out of fuel


Premium Diesel

We offer Cenex premium diesel fuels, including Ruby Fieldmaster for offroad use and Roadmaster XL for road use. 

These fuels contain an additive package to delivery power and performance in the toughest conditions. The detergent package delivers 4.5% more power, 5% better fuel economy, and it is 40% more effective at breaking down harmful engine deposits.


We offer quality Cenex gasoline in various octanes, and with or without ethanol.

Custom fuels

We provide blends of ethanol/gasoline and soy/biodiesel upon request. We can blend to whatever specifications you’d like – B5, B10, etc.

The lease is for a period of ten years after which time you will own the tank. Please call the office, or talk to Randy Numedahl, Randy Huinker, Jeremy Monroe, Duane Holthaus or Matt Corlett about getting set up.
