SUN COMPANY, INC.

American holding company with a primary interest in petroleum. Headquarters are in Radnor, Pa. The company was incorporated in 1971 as the successor to a New Jersey oil and gas business incorporated in 1901. The earlier company had been formed as the Sun Oil Company of Ohio in 1886. In 1975 the Sun Company was restructured into 14 separate business units to provide flexibility in expanding into areas not related to its petroleum business. Among its subsidiaries are the Sun Oil Company of Pennsylvania, which is responsible for U.S. manufacturing and marketing, and the Sun Oil Company (Delaware) and several Canadian units, which are responsible for the exploration and production of crude oil and natural gas in North America. While the company continues to be active in the exploration and refining of petroleum and in the marketing of refined-oil and gas products, it has shown increasing interest in coal, geothermal-energy sources, and nonenergy activitiesincluding real estate, industrial-products distribution, and motor-freight transportation. Its gasoline and other refined motor-oil products are sold through independent dealers, primarily in the eastern two-thirds of the United States and eastern Canada, under the trade names of Sunoco and DX. In addition, the company produces lubricating oils, petrochemicals, greases, and specialty oils sold in North America and overseas. The company also engages in shipbuilding and repair and the manufacture of heavy-industrial equipment.
