Tec4 is a specialist manufacturer and distributor of high-quality engine and fuel treatments for all vehicle types.

All Tec4’s products are the result of more than 25 years of research and development and have been rigorously tested in real-world situations to deliver a proven performance advantage. Their products are trusted by thousands of quality garages every single day. When you work with Tec4, you also benefit from our comprehensive marketing support and industry expertise.

Tec4 was born out of our desire to provide the professional motor trade with the most technically advanced engine treatments available, at a competitive price.

Operating at a time when modern driving habits and a greater demand for fuel efficiency dictate a genuine need for effective contamination removal, Tec4 strives to provide a no-nonsense, gimmick-free approach to the supply of engine, fuel and cooling system treatments.

When added to fuel systems, our non-combustible detergent-based treatments clean and lubricate the whole system from the fuel tank through the combustion chamber and out through the exhaust, removing contamination and protecting against corrosion. This helps the fuel to burn more completely, delivering lower emissions, enhanced MPG, improved driving performance and more importantly for garage customers, significant cost savings over the lifetime of their vehicle
