👉 The eos fluid, or EOS (Eutectic Oils) fluid, is a specialized lubricant additive designed to enhance the performance and longevity of engine oils by reducing friction and wear. It is typically used in high-performance engines, particularly those with advanced lubrication systems, to maintain optimal oil viscosity under extreme temperatures. EOS fluid is a blend of synthetic oils that form a protective film on metal surfaces, preventing direct contact and thus reducing heat generation and wear. This fluid is crucial in ensuring efficient engine operation, especially in demanding conditions, by maintaining a stable and effective lubrication layer that protects engine components from damage.
