Application

Castrol React SRF Racing has an exceptionally high dry boiling point, typically 325°C, making it ideal for use under arduous braking conditions such as racing or rallying. Castrol React SRF Racing has a very high vapour lock point (the more important measure of high temperature performance under actual braking conditions), and has the additional advantage of sustaining high vapour lock point characteristics during its service life. In order to achieve the optimum benefits in such applications, advanced materials have been employed in a unique and patented Castrol formulation. The properties of this formulation are such that in order to derive maximum benefit the use of Castrol React SRF Racing should be restricted to not more than eighteen months before draining and refilling.
