A 1962 newspaper ad for Speedway 79. They had just consolidated with Marathon. Submitted by Gary Flinn, who provides this capsule history: Speedway 79 was the brand name for the Detroit Michigan based Aurora Oil Company which was sold to the Ohio Oil Company in 1959. The Ohio Oil Company's brand of gas was Marathon. The Speedway 79 and Marathon brands co-existed until 1962 when the company was renamed to the Marathon Oil Company, at which time the stations were rebranded to Marathon.
The Speedway brand was revived in the early 1970s by Marathon as a company-owned chain
of self-serve gas and convenience stores.
