Steel Ball Run
Much like the Speedwagon Foundation in the previous arcs of JoJo's Bizarre Adventure, the Speedwagon Oil Company was founded by a risk taking entrepreneur striking it rich finding oil in America. Unlike the previous Speedwagon foundation, the Speedwagon Oil Company has no connection to the Joestars except for helping to fund Stephen Steel's Steel Ball Run (race). It is unknown if Robert Edward O Speedwagon founded this company though the etymology of the company name seems to indicate he is the founder.
