We are proud to supply diesel fuel in accordance with the State of Minnesota bio-diesel requirements. When possible, we purchase soy oil from certified soybean processing plants to ensure that we are providing the best-available product while at the same time supporting our local farmers. Contact us today if you would like additional information on blending biodiesel mixtures stronger that the State requirements.


McMahon Oil has the tools to supply your fuel reliably and consistently because we know that your business depends on it. We offer deliveries from 150 gallons up to transport loads (7500 gallons). To meet our agricultural customers’ needs we offer both will-call and scheduled delivery options. Please contact us today to see how we can help you with your fuel needs. Most importantly when you need to order fuel, or have a question, you talk to local people in a local office.


In addition to our standard diesel treatment with Schaeffer’s Fuel Additives, we can both supplement your diesel to improve fuel economy, performance, and storability or address diesel fuel issues you may be having with other fuel additives. Give us a call to discuss the specific fuel properties that you are looking to enhance.
