ampm is the national convenience store brand for BP. It is 100% franchised. In 2012, BP sold the ARCO brand to Tesoro Corp., along with its Southern California refining and marketing business. BP exclusively licensed rights from Tesoro for the ARCO brand in Northern California, Oregon and Washington. It retained ownership of the ampm c-store brand and franchised it to Tesoro for use in the Southwest. While it formerly had ampm locations across the country, BP decided in 2012 to focus the franchise exclusively in the Western United States.

A key focus for ampm is its food program, which includes coffee, bakery, fresh sandwiches and hot foods, along with an extensive condiment bar. On the dispensed side, the chain offers a large fountain program with up to 24 different flavors of soda and proprietary drinks. Stores have an open floor plan and many have open-air refrigerated cases to display fresh sandwiches, fruit and yogurt.

In packaged beverages, ampm has a line of proprietary drinks under the Deluge and Unbound Energy labels, and across the store has rolled out a value line using a new "ampm Good Stuff" label.
