What does Amoco stand for?

Amoco Corporation, originally Standard Oil Company (Indiana), was a global chemical and oil company that was founded in 1889 around a refinery  located in Whiting, Indiana, United States.

It later absorbed the American Oil Company, founded in Baltimore in 1910 and incorporated in 1922 by Louis Blaustein and his son Jacob. Amoco merged with British Petroleum in December 1998, forming BP Amoco. Shortly after the merger, Amoco stations began a rebranding that saw the stations change their names to the BP marque while continuing to sell Amoco-branded fuel. Eventually all traces of the Amoco brand name were eliminated and the stations adopted the BP branding permanently, although Amoco's grade naming system is still in use.

Although a few Amoco stations still use their former logo, most have since been converted to the BP livery. In St. Louis, Missouri, the largest Amoco sign in the world, both before and after the company's demise, still stands. It stands at the intersection of Clayton Road, Skinker Boulevard, McCausland Avenue, and Interstate 64. It is visible up to two miles away on the interstate. Most surviving Amoco stations are kept so BP can continue holding the trademarks for Amoco and Standard.
