In 1997, American Refining Group, Inc. (ARG), a privately held energy company headquartered in Philadelphia, PA, purchased the Kendall/Amalie refinery located in Bradford, PA, from Witco Corporation. As a result of the sale by Witco, of the Kendall® and Amalie® brands to a third party, a new name was given to the products produced at the site: Brad Penn® Premium Pennsylvania Grade Lubricants. Founded in 1881 at the height of the domestic oil boom, the Bradford refinery is the only refinery processing 100% Pennsylvania Grade crude oil. It is also the oldest continuously operated lube oil refinery in the world. Due to the consistency of our feedstocks, the quality of our products can be traced from the wellhead to the finished packaged product. ARG's refinery and blending and packaging operations are ISO 9001:2000 certified. The Bradford refinery was the first in the United States to carry the ISO 9002 certification.
