Discover Sunoco's History

The History of Sunoco

Sunoco has grown from its humble roots as a small oil company in Pittsburgh, PA, to one of the largest fuel distribution companies in the United States. Sunoco's rich, 130 plus-year heritage, legacy and reputation for innovation, and commitment to its local communities are foundational elements of this iconic American brand. Today, Sunoco distributes fuel to over 5,000 gas station locations in more than 30 states.

1886 Pennsylvania Roots

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.

On March 17, 1890, they made it official with a new name. The Sun Oil Company was producing, transporting, and storing oil as well as refining, shipping, and marketing petroleum.

1916 Expanding to Shipbuilding

As the oil company grew, it expanded into related services and subsidiaries. In 1916, the Sun Shipbuilding and Dry Dock Company was established.

1920s First Service Station

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 – 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.

1937 Landmark in Refining Industry

One of the most dramatic events of the 1930s for the company, and the refining industry, took place when Sun placed on stream the world's first large-scale, commercial catalytic cracking plant in Marcus Hook, PA, in 1937. The Marcus Hook plant is still owned and in operation today, serving as a refining facility location for the company's race fuels.

1941 Expanding to Mining

Always striving to produce better products, Sun got into the mining business in 1941, forming the Cordero Mining Company in Nevada to supply mercury for Sunoco motor oils. The metal proved vital for the United States Military in World War II.

1950s Beyond the States

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.

1956 Invention of the Custom Blending Pump

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.

1960s Relationship with Motorsports Begins

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.

1970s Reshaping the Company

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.

1980s Ultra Release

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 the late 1980s, Sun Company, Inc. began rebranding its fueling stations under the name Sunoco, to match the name of its gasoline.

1998 New Name

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