Castrol React SRF Racing has an exceptionally high dry boiling point ( typically 320°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..
Castrol React SRF Racing is suitable for all disc and drum brake systems with the exception of those for which mineral oil is prescribed. It is miscible with all conventional fluids meeting US Federal Standards FMVSS 116 DOT 3 and DOT 4, ISO 4925 and current SAE J 1703 and J1704
