AMSOIL Propylene Glycol Antifreeze & Engine Coolant

AMSOIL Antifreeze & Engine Coolant is a high-performance automotive fluid designed to provide superior protection against freezing, boiling, and corrosion. This specific formula utilizes Propylene Glycol, known for its lower toxicity compared to conventional ethylene glycol alternatives, making it a preferred choice for many environmental and safety-conscious consumers.

The AMSOIL brand is deeply rooted in American automotive history. It was founded in Superior, Wisconsin, by Al Amatuzio, a former jet fighter squadron commander. The company earned its place in history by developing the world’s first API-qualified synthetic motor oil, and it has since maintained a reputation for premium quality and technical innovation. All AMSOIL products are manufactured and blended in the United States at their primary state-of-the-art facility in Wisconsin.

AMSOIL remains an independent, family-owned company, which is a rarity in the global lubricants industry. It is not currently owned by a multi-national petroleum conglomerate. The company continues to operate under the leadership of the Amatuzio family, focusing on direct-to-consumer and dealer-based sales models across North America.
