Castrol SRF is a high performance brake fluid of special value in competitive motor sport where extreme braking conditions are encountered. It is an exclusive Castrol product registered under patents in many countries. Castrol SRF exceeds US Federal Standards FMVSS 116 DOT 3 and DOT 4, ISO 4925, JIS K2233 and current SAE J 1703.


Castrol SRF has been especially formulated to maximise braking performance under arduous competitive conditions. In order to achieve the optimum benefits in such applications, advanced materials have been employed in a unique and patented Castrol formulation. The use of Castrol SRF should be restricted to not more than eighteen months before draining and refilling for maximum efficiency. Prolonged use in excess of the recommended period may give rise to a deterioration in performance at very low temperatures. Castrol SRF is suitable for all disc and drum brake systems with the exception of those for which mineral oil is prescribed.


The exceptionally high dry boiling point, (higher than 300oC) makes Castrol SRF ideal for use under arduous braking conditions such as racing or rallying. Mixing Castrol SRF and conventional brake fluids will merely reduce the higher quality of Castrol SRF. It is, therefore, recommended that conventional brake fluids be drained from the system before flushing and refilling with Castrol SRF.
