A.T. Williams Oil Co.
A.T. Williams Oil Co. is an oil distribution company based in Winston-Salem, North Carolina. It was started by Arthur T. Williams Sr. in 1963. The gas stations it operates are called WilcoHess because they are co-owned by the Hess Corporation. In 2004 WilcoHess merged with SERVCO and acquired 50 stations in North Carolina. In 2014, it along with the rest of the Hess gas chain was acquired by Speedway LLC and will be converting those stations to the Speedway brand by 2016.
