UTOCO came from the first Utah Oil Refining Company that was formed in 1908. It was originally called The Utah Oil Refining Company and then changed after Standard purchased over 50% of the Stocks to UTOCO and used the typical Standard Logo which they kept for their many name changes of UTOCO, American, Standard, Pan Am, and Amoco. Unlike other Gas/Oil Companies they re used the same sign rings with each of the changing signs. Very convenient for Collectors like us as it is a pain with all the other Companies who changed frames all the time as well as signs. Hooray for universal sign sizes!
