👉 The Carroll fluid, also known as Carroll motor oil, is a synthetic lubricant developed by Carroll Engineering in the 1960s to address the limitations of conventional mineral oils used in automotive engines. It is a high-performance, multi-grade oil designed to provide superior protection and efficiency across a wide range of operating temperatures. Unlike mineral oils, Carroll fluid is formulated to maintain its viscosity and lubricating properties over a broader temperature spectrum, reducing wear on engine components and enhancing fuel efficiency. Its unique molecular structure allows it to form a protective film on metal surfaces, minimizing friction and preventing metal-to-metal contact. This makes Carroll fluid particularly effective in extreme conditions, such as high heat or cold, and it has become a standard in modern automotive maintenance due to its reliability and performance benefits.
