At the 1937 Great Lake Exposition, Sohio sponsored an oil industry exhibit. A 5,000 foot working model of an oil refinery was brought in from Chicago's Museum of Industry. The exhibit demonstrated the process of refining crude oil to its final treatment as gas, asphalt, oil, grease, and parafin. W. T. Holliday, the president of Sohio, was also president of the Great Lakes Exposition in 1937.
