Description: 1954 Charles Dwight (Doc) Liggett, Jim Hill and Robert DeHart began packaging STP Oil Treatment in a backyard garage at night and selling it from the trunks of their cars during their business and pleasure trips. By the end of 1966, sales had climbed to more than $43 million. In 1969, STP® became a public corporation, and shares went on the American Stock Exchange under the symbol “STP”. STP sponsored its own Indy Car racing team, featuring Mario Andretti, the winner of the 1969 Indianapolis 500.
