Standard Oil Co. (Ohio) is changing its name.

The company, known to many as Sohio, reported that it plans to put an end to its corporate identity crisis and from now on will refer to itself only as The Standard Oil Co. A company spokesman said the change was prompted by a consultant’s study that found that, while Standard Oil is ranked 24th on the latest Fortune 500 list, it is not well known beyond the boundaries of Ohio. The company gave no estimate of what it will cost to make the necessary changes in advertising and stationery.
