Amoco Corporation (until 1985, Standard Oil Company (Indiana)) is a global chemical and oil company that was founded in 1889 around a refinery located in Whiting, Indiana, United States. Originally part of the Standard Oil Trust, it focused on gasoline for the new automobile market. In 1911, during the break up of the trust, it became an independent corporation. Incorporated in Indiana, it was headquartered in Chicago.
In the 1930s it absorbed the American Oil Company, with the combined corporation of operated or licensed gas stations under both the Standard name and the Amoco name, and its logo using either name became a red, white and blue oval with a torch in the center. In 1985, it changed its corporate name to Amoco (Am(erican) O(il) Co(mpany)).
It was merged with British Petroleum to make BP Amoco. The brand was on hiatus until 2017, when BP reintroduced the Amoco name to select markets in America.
In NASCAR, Amoco is best known for sponsoring Dave Blaney from 1998 through 2001, as well as promoting its "Ultimate" premium fuel.
