Optimum, already established in Europe and launched in the U.S. last fall, will handle U.S. buying for fuels, lubricants and global brand advertising.
Other contenders for the account included incumbents Ar-nold Communications, Boston and Washington; and Grace & Rothschild, New York. Western International Media, Los Angeles, also competed for the business.

Optimum will handle all national buys as well as local radio buying for Mobil's convenience stores, now at Arnold's Washington office. That office will continue to do creative and planning.
