What Makes W&H Cooperative Fuel Better Than Standard Diesel and Propane
Since 1929, W&H Cooperative has been owned by local members and rooted in Iowa communities from Humboldt to Hamilton County. But what truly sets W&H Cooperative apart today is the quality and formulation of its fuel products. Here’s how W&H’s gasoline, diesel, and propane outperform standard market fuels.

Premium Fuel Additives That Deliver Real Benefits
In both gasoline and diesel, W&H uses premium additive packages designed to:
- Reduce engine deposits and injector fouling, keeping motors clean and efficient
- Enhance fuel economy and combustion consistency, meaning better mileage and power
- Protect fuel systems, with corrosion inhibitors, water separators (demulsifiers), and lubricity agents These additive-enhanced fuels help extend engine life and boost operational reliability—advantages that generic fuels often don’t offer.
Specialized Diesel Options for Different Needs
Ruby Fieldmaster™ and Roadmaster XL™ are two diesel fuels tailored to specific use cases:
Ruby Fieldmaster™ (Off-Road Diesel)
Ruby Fieldmaster™ (Off-Road Diesel)
Dyed red for non-road/agricultural use (no road tax)
Same high-performance additive blend as Roadmaster XL
