Involvement in motor racing and sponsorships In 1970, STP CEO Andy Granatelli founded the STP Formula One Team. Mario Andretti was hired to drive. The team competed in a total of five races running a March Engineering chassis, their best result being a third place at the 1970 Spanish Grand Prix. In 1972 Granatelli agreed to sponsor NASCAR champion Richard Petty, but their deal almost fell apart before their first race. Granatelli insisted the car be STP day-glo red. Petty held out for his iconic Petty blue, and neither would budge. The resulting two-tone red and blue scheme became more famous than either color alone. STP sponsored Petty through the end of his driving career in 1992, then Bobby Hamilton, and John Andretti in Petty Enterprises' famous #43. That partnership ended shortly after its acquisition by Clorox. STP and the Petty family hold the second-longest relationship in automobile racing history (1972–2000) (Kenny Bernstein and his son Brandon were sponsored by Budweiser for two years longer (1979–2009)). In August 2012, STP announced that it would be the title sponsor of the World of Outlaws Sprint Car Series in 2013. On February 21, 2013, STP announced a return to NASCAR Sprint Cup Series sponsorship in a multi-year deal for the STP Gas Booster 500 starting April 7, 2013 at Martinsville Speedway along with a return as primary sponsor of the Richard Petty Motorsports No. 43 for the 2013 STP Gas Booster 500. STP also sponsored the Xfinity Series race STP 300 from 2011 to 2013 at Chicagoland Speedway.
