Sunoco

1800s to 1950s: founding and growth

The partnership began as The Peoples Natural Gas Company in Pittsburgh, Pennsylvania. In 1886, its partners – Joseph Newton Pew, Philip Pisano, and Edward O. Emerson – decided to expand their gas business with a stake in the new oil discoveries in Ohio and Pennsylvania. Four years later, the growing enterprise became the Sun Oil Company of Ohio. Sun Oil diversified quickly, active in production and distribution of oil as well as processing and marketing refined products. By 1901, the company was incorporated in New Jersey as Sun Company.

In 1902, the Sun Oil Refining Company was chartered in Texas, as it turned its interest to the new Spindletop field in Texas. Joseph Pew's nephew, J. Edgar Pew, was able to buy the storage and transportation assets of Lone Star and Crescent Oil Company at a receivership auction. Spindletop oil was then shipped to the company's Marcus Hook, Pennsylvania, refinery.Pew's sons, J. Howard Pew and Joseph N. Pew Jr. would take over the company after their father's death.

With a growing portfolio of oil fields and refineries, Sun opened its first service station in Ardmore, Pennsylvania in 1920. In 1922, it changed its name back to Sun Oil Company and, in 1925, it became a public company via an initial public offering on the New York Stock Exchange. Sunoco ranked 39th among United States corporations in the value of World War II production contracts. Sun expanded internationally following the war. Its first Canadian refinery was built in 1953 in Sarnia, Ontario, home to a burgeoning new petrochemical industry. Sun established a facility at Venezuela's Lake Maracaibo in 1957, which produced over a billion barrels before the operation was nationalized in 1975.

Custom blending

In 1956, Sunoco introduced "custom blending" pumps, an innovation that allowed customers of Sunoco service stations to choose from several octane ratings through a single pump. Sunoco stations offered as many as eight grades of "Custom Blended" gasolines from its "Dial A Grade" pumps ranging from subregular Sunoco 190 to Sunoco 260, the latter a super-premium grade of 102 octane that was advertised as the "highest octane pump gas" and very popular with operators of V8-powered muscle cars of the 1960s.

1960s to 2000s: acquisitions and branding

In 1967, Sun established its Great Canadian Oil Sands Limited facility in northern Alberta, Canada, to access the estimated 300 billion barrels of extractable oil in the Athabasca oil sands.In 1968, Sun Oil merged with Tulsa, Oklahoma-based Sunray DX Oil Company, which refined and marketed gasoline under the DX brand in several midwestern states, and included several refineries. Its Tulsa refinery was operated by Sun until its sale in June 2009 to Holly Corporation of Dallas. This move expanded Sun's marketing area into the mid-continent region.

Sun Oil continued marketing its petroleum products under both the Sunoco and DX brands through the 1970s and into the 1980s. In the late 1980s, Sun began rebranding DX stations in the Midwest to the Sunoco brand, but by the early 1990s, they pulled out of virtually all areas in the southeastern U.S. and west of the Mississippi, resulting in the closing and rebranding of service stations and jobbers to other brands in those areas, notably Sinclair in Oklahoma and Kerr-McGee in Arkansas.

With increased diversification, Sun Oil Company was renamed Sun Company in 1976. In 1980, Sun acquired the U.S. oil and gas properties of Texas Pacific Oil Company, Inc., a subsidiary of The Seagram Company, Ltd., for US$2.3 billion—the second largest acquisition in U.S. history to that date.

Through the 1980s, Sun developed oil interests in the North Sea and offshore China and expanded its holdings in both oil and coal with additional U.S. business acquisitions. In 1983, Sun Oil launched Sunoco ULTRA 94, the market's highest octane unleaded gasoline. Then in 1988, Sun undertook a restructuring to segregate its domestic oil and gas exploration and production business and the focus the company on its refining and marketing business. This led to the acquisition of Atlantic Refining and Marketing , including its Philadelphia refinery which was later merged with the former Gulf Oil refinery next door that Sunoco acquired from Chevron.

By the 1990s, Sun had departed the international exploration business and was fully dedicated to its branded products and services. In 1994, Sunoco acquired the Philadelphia Chevron Oil refinery consolidating operations with its own adjacent which it had acquired with Atlantic. Sun sold its remaining interest in Canada's Suncor Energy in 1995, but markets product from two refineries – one in Toledo, Ohio, and the other Sarnia, Ontario – in joint ventures. In 1998, Sun Company, Inc. became Sunoco, Inc. In 2011 the Toledo facility was sold to PBF Energy.

In 1998, Sun acquired the chemical business of Allied Signal, including a phenol plant. The business was renamed as "Sunoco Chemicals, Inc." In 2011, the plant was acquired by Honeywell for $85 million.In 2003, Speedway LLC, then a subsidiary of Marathon Petroleum, sold 193 convenience stores to Sunoco. It also acquired many service stations from Coastal Petroleum.

In 2004, Sunoco replaced the ConocoPhillips' 76 brand as the "Official Fuel of NASCAR."After ConocoPhillips abandoned the marketing of the Mobil brand name in the Washington, D.C., area, Sunoco purchased these rights, converted Maryland and Virginia Mobil stations to the Sunoco brand, bringing the A-Plus convenience store with them – prior to this, these stations had convenience stores under the Circle K or On the Run brands.

In September 2009, Sunoco sold its retail heating oil and propane distribution business to Superior Plus for $82.5 million in cash.In 2012, Sunoco demolished its Eagle Point refinery complex in West Deptford Township, New Jersey, which had been idle since 2010.In Canada, the Sunoco brand was licensed for the Ontario retail gas station operations of Suncor Energy until 2010. Following Suncor's acquisition of Petro-Canada, all Canadian Sunoco outlets were converted to Petro-Canada branding, except for one location in Port Colborn, Ontario.

Exit from refinery business

In December 2010, Sunoco sold its refinery in Toledo, Ohio to PBF Energy for $400 million. Effective September 6, 2011, Sunoco announced that it would exit the crude oil refining business and seek to sell its Philadelphia and Marcus Hook refineries by mid-2012. The company has said that its cost for exiting the refining business could be as high as $2.7 billion. According to one report, the company had lost some $800 million on refining operations since 2009; an earlier report provided a figure of $772 million.

On December 1, 2011, Sunoco announced it would accelerate closure of the Marcus Hook facility. The Marcus Hook facility, founded in 1902 and covering 781 acres, was dedicated exclusively to the processing of light sweet crude oil; this processing focus combined with volatility in crude oil prices are considered contributing factors to both this refinery's closure and Sunoco's exit from the refinery business.

Joint venture, bankruptcy, and future closure

In September 2012, Sunoco formed a joint venture with The Carlyle Group, allowing for the continuation of operations at the Philadelphia refinery, and temporarily saving over 800 jobs. However, on January 22, 2018, the joint venture, named Philadelphia Energy Solutions, filed for bankruptcy. The bankruptcy announcement was followed by a damaging fire on June 21, 2019, which occurred at the 30,000 bpd alkylation unit. The explosion of the alkylation unit triggered a massive fireball and caused nearby homes to shake. A few days later, on June 26 the refinery complex announced it would cease operations and shut down.

Sale to Energy Transfer Partners and merger with Susser Holdings

In 2012, Dallas-based energy company Energy Transfer Partners purchased Sunoco. Sunoco would subsequently move its corporate headquarters to Dallas in 2016.In 2014, Energy Transfer Partners acquired Susser Holdings Corporation, the parent company of Stripes Convenience Stores, and merged it with Sunoco into a master limited partnership, forming Sunoco LP. In Texas, the Sunoco brand replaced Valero Energy at the Stripes locations; Stripes and A-Plus remained separate brands.

Also in 2014, Sunoco LP acquired Aloha Petroleum.In 2015, Aloha Petroleum acquired stores including a Subway in Hawaii.Additionally, Sunoco LP purchased eight Pico convenience stores in South Central Texas.In December 2015, Sunoco LP completed its acquisition of Alta East, Inc., a wholesale motor fuel distribution business serving the northeast United States.In June 2016, Sunoco LP purchased Valentine Convenience stores, consisting of 18 locations selling more than 20 million gallons of fuel, as well as Texas based Kolkhorst Petroleum, Inc.

Introduction of Sunoco UltraTech and Top Tier fuel

In April 2017, Sunoco introduced at all of its stations Sunoco UltraTech, a high detergent fuel blend that met Top Tier standards. Sunoco UltraTech contains the same detergent level as the fuel Sunoco makes for NASCAR.

Sale of stores to Seven & I Holdings Co.

In January 2018, the company sold 1,030 retail stores to 7-Eleven and agreed to supply 2.2 billion gallons of fuel to 7-Eleven convenience stores annually for 15 years. This included Sunoco's contract to the service plazas along the Pennsylvania Turnpike.
