Demmer Oil Company offers top-quality Biodiesel. On-site, we can mix your Biodiesel to your desired blend.

We blend only high quality vegetable oil, with the majority of the oils provided locally from Western Dubuque Biodiesel, located in Farley, Iowa. We proudly support our community and our local area businesses!

Benefits of Biodiesel include:

  • Potential cost savings

  • Increases fuel lubricity

Low sulfur/aromatic diesel fuel can cause premature wear and scuffing of pumps and injectors. Wear that can lead to premature failure and expensive repairs. By using Biodiesel, it protects your injectors and fuel systems from wear.

  • Raises cetane number of the fuel

  • Supports local farmers within our community
