Castrol Isolube provides excellent performance in circulating oil and gear set applications. It contains technically advanced chemistries that exceed the performance levels historically attributed to the traditional synthetic products. Castrol Isolube excels in applications requiring optimum oxidation control and thermal stability, consistent in anti-wear performance, and low carbon forming tendencies. The uniqueness of Castrol Isolube is most visible in compressors that operate under severe field and industrial conditions. Castrol Isolube has viscosity range properties for low temperature fluidity and controlled volatility. Other exceptional benefits of this innovative formulation include superior rust protection, consistent demulsibility and hydrolytic stability.
