Castrol React SRF Racing has an extremely high dry boiling point, typically 325°C, making it ideal for use in tough braking conditions such as racing or rallying. Castrol React SRF Racing has a very high gas lock point (the more important measure of high temperature performance under real braking conditions) and has the added benefit of maintaining the high gas lock point characteristics over its service life. To achieve the best benefits in this type of application, advanced materials are used in Castrol's unique patented formulation. Due to the nature of this formulation, the use of Castrol React SRF Racing should be limited to no more than 18 months before draining and refilling in order to obtain maximum benefits.
