when did sinclair oil go out of business
Sinclair Oil Corporation In 1969, Sinclair was acquired by the Atlantic Richfield Company (ARCO). Federal antitrust provisions required the new entity to divest itself of certain Sinclair assets, and as a result, the East Coast operations of Sinclair were sold to BP (which has since purchased ARCO). After the acquisition by ARCO, the dinosaur was phased out, but at least one service station, in Winona, Minnesota, retained the original look through the 1980s. Many Sinclair stations in the Midwest continued to use the dinosaur logo along with ARCO's "diamond spark" logo. At least some Sinclair stations partially retained the Sinclair brand for a time, using ARCO's blue rectangular logo including the "spark" graphic, but with the word "Sinclair" substituted for ARCO.
