In October 1954, three businessmen with a mere $3,000 in start-up capital introduced the first STP® product in St. Joseph, MO. Scientifically Treated Petroleum, better known as STP®, began with one product — STP® Oil Treatment. It helped automobile motor oil resist thinning at high temperatures and pressures.
STP is an American brand of automotive aftermarket products, especially lubricants such as motor oil and motor oil additives. The name began as an abbreviation of Scientifically Treated Petroleum. The brand has been owned by Energizer Holdings since November 2018.
STP® continues to build on its rich history of racing by sponsoring the National Championship ‘STP Sportsman Series’ at Santa Pod Raceway in Northampton shire, UK - home of European Drag Racing.
