Welcome to Corey Oil

Our mission is to deliver the highest quality fuel, oil, and lubricant products at competitive prices in a safe, timely, and environmentally responsible manner while providing better lives for our employees and communities around us.


Since 1980

Corey Oil was started by John & Valerie Schweitzer who purchased a small bulk plant with one truck in Columbus, WI with a $100,000 loan from the bank at a time when interest rates were at 21%. The bulk plant came with a contract to sell Mobil fuels and Mobil packaged lubricants. The Schweitzer household’s kitchen table became the Corey Oil office.

Corey Oil - A Community Partner

Corey Oil enjoys working hard so we can give back. Giving back is a planned part of our operations and structure. Each and every year we donate to many quality charities and will continue to do so indefinitely. Corey Oil only contributes to charitable organizations in which a very high percentage of the donation dollars goes to the intended recipients, not to overhead costs. We also contribute to charities where the value of the donation has a direct impact on the betterment of a small community.

Below is a list of charities and communities to which Corey Oil has made donations. We hope our contributions continue to bring attention to these organizations as well as help to provide a positive impact for years to come.
