Campbell Oil Co.

Campbell Oil Co. acquired The Hartley Co. in October 2019, adding 16 Starfire c-stores to its portfolio. The Hartley Co. also operated petroleum marketing locations in Ohio and distributed wholesale fuels to multiple company-owned dealer-operated sites and open dealers.

Campbell Oil opened its first c-store in 1985 and operates more than 70 locations today under the BellStores name and sells Marathon-branded fuel. In addition to offering the Bell's Bistro proprietary program of salads and subs, some stores are co-branded with Subway, Dairy Queen and Domino's quick-service restaurants.

For benchmarking purposes, store counts are year-end 2019.
