Headquartered in Marshall, OK, Earnheart Oil was established in 1971 by Ernest Earnheart. Since its beginning, the company has grown to over 40 employees.

In 1989, Edmund & Shirley Earnheart took over the operations of Earnheart Oil from Edmund's father. At the time, the company consisted only of a single full service gas station in Marshall, OK.

Edmund and Shirley's entrepreneurial spirit and hard work allowed Earnheart Oil to grow not only geographically, but also expand its product offerings. Through a series of acquisitions and organic growth, Earnheart Oil has become one of the larger bulk fuel and propane suppliers in Central Oklahoma.

Earnheart Oil is now a third-generation, family-owned business that serves multiple counties and communities across Central Oklahoma. We provide full service fuel and propane delivery to the residential, oilfield and agricultural sectors.
