[1] The Richfield Oil Corporation was founded in 1911,[2] and opened its first automotive service station in Los Angeles in 1917.

[3] After quick expansion, Richfield Oil Corp fell to the Great Depression and went into receivership in 1931.

Consolidated Oil Corp, in 1935, bought Richfield's eastern United States operations.

[9] During World War II, two Richfield Oil tanks were bombarded by the Imperial Japanese Army on February 23, 1942, in an attack on the Ellwood oil field, which is west of the city of Santa Barbara in California.

[13][14] Richfield's success at Kenai helped push their leasing tracks at Prudhoe Bay, which later served to benefit ARCO.

Later, with former Hondo president Robert O. Anderson at the helm, Atlantic Refining continued its mergers and acquisitions.
