STP Oil Treatments & Products

For 60 years, STP have been one of the most trusted names in automotive care.

Whether you’re a regular car enthusiast, a keen DIY-er or a professional racer, you can rely on STP oil additives, power steering fluids and more to keep your vehicle running better, for longer.

Perfect for those who want to take ownership of their vehicle’s maintenance, STP was founded by three gentlemen in America, beginning with only one product - the well-renowned STP Oil Treatment.

In October 1954, the founders of STP started packaging STP Oil Treatment in a garage at night, selling their wares from the trunks of their cars during business trips across the country.

By the early ‘70s, STP were selling their incredible products across the world - from the US to Canada and Mexico, growing to over 100 countries in total selling their revolutionary products.

To this day, STP still create exceptional products to provide all car owners and professionals with simple DIY solutions to everyday motoring problems;
