In this guide, we’ll take a closer look at the Valvoline Zerex brand, its history, and the products it offers.

History of Valvoline Zerex
Valvoline is a brand that has been a household name in the automotive industry for over 150 years. The company was founded in 1866 by Dr. John Ellis, who developed a petroleum-based lubricant that was superior to animal fat and vegetable oils used at the time. This revolutionary lubricant became known as Valvoline, and the brand quickly gained a reputation for quality and performance.
Over the years, Valvoline has continued to innovate and expand its product line, offering a range of automotive fluids, including motor oil, transmission fluid, brake fluid, and coolant. Today, Valvoline is a global leader in the automotive industry, serving customers in over 140 countries around the world.
Zerex was originally a brand owned by the German BASF, a giant in the chemical industry that experienced massive success with this line of antifreeze. However, BASF sold the Zerex brand to Valvoline in the ‘90s, who then took this popular line of antifreeze to a whole new level. Today, Zerex is one of the most recognizable brands in the automotive coolant niche, enjoying high levels of popularity among enthusiasts and professionals alike.
