Overview
Amoco was the principal consumer and corporate brand associated with the former Standard Oil Company of Indiana, an American integrated petroleum and chemicals business. Its corporate roots reach back to 1889, when Standard Oil established operations around the Whiting refinery in Indiana. After the 1911 dissolution of the Standard Oil trust, Standard Oil of Indiana continued as an independent company with a large Midwestern marketing territory. It developed from a regional refiner and fuel marketer into a vertically integrated energy group involved in exploration, production, pipelines, refining, transportation, fuel retailing, natural gas, petrochemicals, chemicals, minerals and international ventures. The company’s history also incorporated the American Oil Company, founded in Baltimore in 1910 by Louis Blaustein and Jacob Blaustein. Standard Oil of Indiana acquired American Oil’s parent interests in the 1920s, and the combined businesses operated under several names, including Standard, American and Amoco. The Amoco identity became increasingly prominent outside the traditional Standard marketing territory. By 1971, the company’s operating divisions had broadly adopted the Amoco name, and in 1985 the corporate name was changed from Standard Oil Company of Indiana to Amoco Corporation. Amoco’s public identity was built through refining, pipelines, gasoline distribution and a large network of service stations. It was also associated with technical developments, including William Burton’s thermal-cracking process, early offshore drilling in the Gulf of Mexico, and Hydrafrac, a hydraulic-fracturing technique developed by Stanolind Oil in the postwar period. The company marketed a premium lead-free gasoline decades before leaded fuel was broadly phased out in the United States and later became one of the first major oil companies to announce the end of retail sales of leaded gasoline. During the second half of the twentieth century, Amoco expanded internationally and diversified into chemicals, synthetic fibers and plastics. It operated or invested in projects across Europe, Canada, Latin America, the Middle East, Asia and other regions. Its scale made it one of the largest American oil companies, although the corporation later sold or reorganized some non-core chemical and manufacturing activities. In December 1998, Amoco merged with British Petroleum to form BP Amoco. The combined company gradually consolidated its identity under the BP name and was renamed BP in 2001. Amoco therefore ceased to exist as an independent listed company, while BP retained ownership of the trademark and later reintroduced Amoco-branded fuel stations in selected United States markets. The revived retail brand does not represent the restoration of the former independent Amoco Corporation.
History
Amoco’s corporate lineage began in the Standard Oil system. Standard Oil established the Standard Oil Company of Indiana in 1889 around its Whiting, Indiana, refinery, which began operating in 1890. The company initially served the American Midwest and became independent when the Standard Oil trust was dissolved in 1911. Its assigned marketing territory included Indiana and much of the surrounding central United States. In 1912, it opened an early service station in Minneapolis, reflecting the growing importance of automobiles and retail gasoline. The company expanded its technical and logistical capabilities quickly. William Burton developed a thermal-cracking method that increased the amount of gasoline obtainable from crude oil, and Standard Oil of Indiana licensed the process to other oil companies. The company also acquired pipeline interests and oil-production assets, including interests associated with Sinclair and Midwest Refining. Its Stanolind organization, established in 1931, consolidated exploration and production activity. By the 1930s, the company was drilling extensively and operating refineries and pipelines across the central United States. A major addition to the corporate story came from the American Oil Company. Louis and Jacob Blaustein founded the business in Baltimore in 1910 and incorporated it in 1922. Standard Oil of Indiana acquired the interests of Pan American Petroleum and Transport, which held part of American Oil, in 1925. Standard and American brands were subsequently used in different territories and were linked by a red, white and blue oval logo containing a torch. The company also acquired or developed substantial refining, pipeline and production operations, making it one of the largest American oil companies by the middle of the twentieth century. The business contributed fuels and refining expertise during the Second World War and created a chemicals division from earlier chemical operations. After the war, it pursued offshore drilling in the Gulf of Mexico and developed Hydrafrac, a hydraulic-fracturing process that was initially licensed to Halliburton. It continued to diversify into chemicals, polyester-related materials, synthetic fibers and foam products. Some of these activities were later sold or reorganized as the corporation concentrated more heavily on energy. Brand architecture changed over several decades. Pan-Am stations in the southeastern United States were converted to Amoco stations in 1956. In 1961, Standard and American names were assigned to different marketing territories while sharing common visual elements. By 1971, the company’s divisions had adopted Amoco branding, and the former Standard Oil Company of Indiana formally became Amoco Corporation in 1985. During this period, Amoco expanded outside the United States and developed interests in Canada, Europe, the Middle East, Latin America and Asia. It withdrew from Iran after political upheaval and threats during the 1978 revolution, while continuing other international operations. Amoco’s consumer reputation was particularly connected with its fuel stations and gasoline products. Its Amoco Super-Premium gasoline used non-lead octane enhancement long before environmental regulation forced the broad removal of lead from gasoline. In 1986, the company announced that it would end retail sales of leaded gasoline. The business also operated one of the largest pipeline systems in the central United States and maintained a broad portfolio spanning upstream, midstream, refining, marketing and chemicals. The decisive corporate turning point came in December 1998, when Amoco merged with British Petroleum. The resulting BP Amoco organization later adopted the BP name in 2001. Amoco stopped operating as an independent corporation, though BP retained the trademark. Following damage to BP’s United States reputation after the 2010 Deepwater Horizon disaster, BP reconsidered its domestic brand portfolio and announced in 2017 that it would bring back Amoco-branded stations in selected markets. The current Amoco identity is therefore a BP-owned retail brand rather than the former standalone integrated oil company.

Products and positioning
Historically, a large vertically integrated American oil, gas, chemicals and fuel-retailing company; today, a BP-owned fuel-station brand in selected United States markets.
Fuel retailing
Petroleum fuels
Gasoline, kerosene and related refined petroleum products formed the core of Amoco’s consumer business. The company supplied fuels through its refineries, pipelines, wholesale network and service stations operating under Standard, American and later Amoco identities.
Motor fuel
Amoco Super-Premium gasoline
Amoco’s premium lead-free gasoline used aromatic compounds to raise octane rather than relying on tetraethyl lead. It was marketed well before leaded gasoline was broadly eliminated in the United States and became an important part of the company’s technical and environmental positioning.
Natural gas
Natural gas
Natural gas was part of Amoco’s integrated upstream and marketing portfolio. Activities included exploration, production, transportation and commercial sale, alongside the company’s crude-oil and refining operations.
Chemicals
Petrochemicals and chemicals
Amoco operated chemical businesses connected to petroleum feedstocks and industrial manufacturing. Its portfolio included materials related to polyester fibers, plastics and other chemical applications, although individual activities changed through acquisitions, divestitures and reorganizations.
Midstream energy
Pipeline transportation
Pipeline transportation was a major infrastructure activity, moving crude oil from producing areas to refineries and transporting petroleum products through the central United States. The pipeline network was consolidated into Service Pipeline Company in the postwar period.
Controversies
