About Us

Our History

Offen has a long history of providing fuel into the right tank, at the right time, every time. Offen Petroleum began its story as Reedy Coal and Fuel Company in the late 1930’s. In 1967, Jim and Ester Offen purchased the company and changed the name to Offen Petroleum, which it still is today. Since then, the company has grown to be one of the largest fuel distributors in the country and has expanded its offerings to now include propane, lubricants, DEF, and fuel-handling needs.

We serve a broad range of commercial and industrial fuels and lubricants accounts, as well as retail gasoline outlets throughout the country. Offen’s team of 200+ experienced drivers combined with longstanding supply relationships, modern fleet, scalable processes and systems, and best-in-class team, will continue to safely deliver superior levels of customer service and a full slate of motor fuel product offerings.
