Wynns - Oil Additives & Treatments

The story of Wynn’s is a classic tale of American innovation that transformed the global automotive industry. It began in 1939 when 70-year-old retired lawyer Chestien Wynn discovered a chemical formula he called "Wynn’s Friction Proofing" Oil. This revolutionary discovery changed the chemistry of metal surfaces, making them more resistant to friction and wear. From a small garage in California, the brand’s reputation exploded during World War II and the post-war era, eventually becoming a staple in every professional garage and enthusiast’s toolbox worldwide
Brand image for Wynns
Today, Wynn’s is part of the ITW (Illinois Tool Works) family, a Fortune 200 company. While their heritage is rooted in oil treatments, Wynn’s has evolved into the world’s leading authority on preventative maintenance and chemical repair. Their modern laboratory facilities in Belgium and the USA focus on the most pressing challenges of contemporary motoring: reducing emissions, optimizing fuel economy, and protecting complex systems like DPFs, EGRs, and AdBlue® SCR circuits. Wynn’s products are often referred to as "a mechanic in a bottle." They offer professional-grade solutions that resolve common vehicle ailments—such as smoky exhausts, blocked injectors, and leaking radiators—without the need for expensive mechanical teardowns. From their luxury Cockpit Shine interior range with premium scents like Royal Oud, to their industrial-strength DPF Regenerators and E10 Protectors, Wynn’s remains at the forefront of automotive chemistry, ensuring vehicles run cleaner, smoother, and longer.
