History

Marathon Ashland Petroleum, LLC was a US based petroleum corporation, formed in 1998 from a merger of the downstream operations of Ashland, Inc., and Marathon Oil. Its corporate headquarters were in Findlay. Marathon owned 62% percent and Ashland owned 38% of this venture.

On September 1, 2001, Marathon formed Pilot Travel Centers, LLC (PTC) in a joint venture with Pilot Corporation. Each company owns 50% of PTC.  

The Speedway SuperAmerica chain of convenience stores was a subsidiary of this now-defunct company. In addition, Marathon Ashland Petroleum owned seven refineries and a number of other pipelines. Following Ashland shareholder and debt-holder approval, the company became fully owned by Marathon Oil on June 30, 2005. The company was renamed Marathon Petroleum Company on September 1, 2005.
