and Exxon in 2001. After Shell's purchase of Pennzoil, there was the possibility that the remaining Pennzoil stations—mostly in western Pennsylvania—would be converted to Shell as part of the company's aggressive movement to expand nationally. This didn't happen, but the three company-owned Pennzoil gas stations in the New Castle, Pennsylvania, area began co-branding themselves with 7-Eleven in 2003, with more emphasis placed on the 7-Eleven brand name than Pennzoil itself. Gradually, BP began replacing Pennzoil at some of these sites in 2006 while retaining 7-Eleven (a Pennzoil in Ambridge, Pennsylvania, also converted to BP at the same time) while others were sold to private owners and became independent, unbranded locations. By the mid-2010s, Pennzoil was no longer selling gasoline.
