[citation needed] Petrofina was founded on 25 February 1920 by Auguste Diagre, Hector Carlier his brother Fernand and Aloys Van de Vyvere as an Antwerp-based group called Compagnie Financière Belge des Pétroles,[1] but changed to PetroFina to reflect their telegraphic address name.

Another expansion of Fina's marketing operations came in 1984, when American Petrofina purchased several thousand service stations from Oklahoma-based Champlin Refining Company following that firm's closing of its Enid, Oklahoma refinery.

The Champlin assets were rebranded as Fina stations in several Mid-Continent states including Texas, Oklahoma, Kansas, Nebraska and Iowa among others.

Fina Inc. planned to occupy 149,000 square feet (13,800 m2) in the World Houston Plaza building, near George Bush Intercontinental Airport.

Since the Total-Petrofina merger in 1999, all of Fina's former marketing assets and the Big Spring refinery have been owned by Texas-based Alon USA.

Alon supplies gasoline and other petroleum products to 1,200 Fina stations directly and through distributors in seven Southwestern states including Texas, Oklahoma, Arkansas, Louisiana, New Mexico, Arizona and the southern portion of Colorado.

Doing so would also allow them to expand beyond the original eight state territory they could use the Fina name in (Arizona, Arkansas, Oklahoma, Texas, Utah, Louisiana, Colorado, and New Mexico).
