HOUSTON — Shell Oil Co. announced that it will grant access to Shell's proprietary payment processing network for customers who use the Fuelman Fleet Card, offering pay-at-the-pump convenience to more than 3,500 Shell-branded retail outlets currently participating in the Fuelman program. As a result of the agreement, Fuelman cards now will be accepted at Shell stations operated by multi-site operators. Shell-branded retailers who elect to participate in the program will be offering an added convenience to more than 1 million active Fuelman cardholders. The Fuelman card authorizes, controls and tracks fleet fueling and maintenance purchases at thousands of locations in the United States. The card is a product of FleetCor, serving more than 40,000 fleets. While Shell Oil Products U.S. will provide accessibility throughout its proprietary payment processing network, each location must enter into its own agreement with FleetCor to allow its customers to use the Fuelman card. All currently participating Shell-branded locations should obtain pay-at-the-pump access for Fuelman cards by the end of June.
