Founded in 1954, Tetrosyl was created to meet the needs of body shops, introducing the first-ever mobile paint mixing system. In 1958, T-Cut (short for Tetrosyl Cutting Oil) was launched and quickly became one of Tetrosyl’s most iconic and recognizable brands. From these humble beginnings, the Tetrosyl Group has grown into one of the most established British brands in recent decades, now owning well-known names such as CarPlan, Carlube, Bluecol, Wonder Wheels, Quinton Hazell, and TJ Filters, among others.
