OPIS defines “price differential” as how a brand’s typical store on a typical day is priced relative to its direct competition; it is measured in cents per gallon (CPG). Many of the top low-price brands among the Fuels 50 belong to warehouse clubs, which offer highly discounted prices to boost memberships. Also in the mix: old-school discounter Arco, and the Murphy USA and Murphy Express brands of former Wal-Mart partner Murphy USA.
