Sunoco's

Joseph Newton Pew and Edward O. Emerson were partners at Peoples Natural Gas Company in Pittsburgh, PA, when they decided to expand their gas business to oil. It proved to be a success. Within a few years, the oil company had acquired pipelines, leases and storage tanks, emerging as one of the area's leading suppliers of crude oil.

Sun opened its first service station in Ardmore, PA, and shortly after, another in Toledo, OH.  On November 12, 1925, Sun Oil Company went public with its stock appearing for the first time on the New York Stock Exchange. Before the decade was over, Sun was in the oilfield equipment business with the 1929 formation of Sperry-Sun, a joint venture with Sperry Gyroscope.

Sun began expanding north and south in the 1950s. In Canada, Sun started a 15,000-barrels-per-day refinery in Sarnia, Ontario. And, in Venezuela beginning in 1957, Venezuelan Sun Oil Company produced more than 1 billion barrels of oil from Lake Maracaibo before ceasing operations in 1975 when the Venezuelan government nationalized Sun's holdings.

Sun revolutionized the oil industry when it introduced the Custom Blending Pump, a novel system for dispensing a choice of five octane grades of gasoline from a single pump. A model of the pump is currently on display at the Smithsonian.

The Sunoco brand officially entered the motorsports scene, forging a partnership with the legendary Roger Penske Racing Team and driver Mark Donohue. This partnership had tremendous success, including winning the 1972, Indianapolis 500.

Major restructuring reshaped the company in 1975, when it organized into 14 operating units, two property companies and a non-operating parent company. This was accompanied by a move to a new corporate headquarters in Radnor, PA. Reflecting the diversification of the company, Sun Oil Company was renamed again to the Sun Company, Inc. in 1976.

With a history of innovation and love of performance, Sun developed and released the market's highest octane unleaded gas, Sunoco ULTRA 94, in 1983. The company discontinued ULTRA 94 in 2005, after a solid 22-year run.

In November of 1998, Sun Company, Inc. changed its name to Sunoco, Inc.

Sunoco is proud to give back to the communities it serves. Over the years, the company has partnered with both national and local organizations to provide financial contributions, fuel donations, and volunteer time to help assist those in need.

In 2004, Sunoco signed on as the Official Fuel of NASCAR®, and more recently IndyCar and the NHRA. In total, Sunoco is the official fuel of more than 50 racing series.
