In 1961, Indiana Standard reorganized its marketing giving its American Oil Company unit responsibility for its retail operations nationwide under the Standard name inside the Indiana Standard marketing area (Colorado, Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Montana, Nebraska, North Dakota, Oklahoma, South Dakota, Wisconsin, and Wyoming) and under the American name outside that region. Both brands shared the same redesigned torch and oval logo for easy identification nationwide. The Utoco name used in Indiana Standard's southwestern region was replaced by the American name. The Amoco name continued to be used outside the U.S. and as a brand on certain American Oil products.
