Description Designed for maximum performance in racing conditions. Most V-car owners who drive their cars hard are using Castrol SRF so you only have to swap fluid annually. Other high temperature fluids are fine if you’re willing to change fluid a couple times a year. Castrol SRF Brake Fluid has a wet boiling point of 518°F (270°C) which exceeds DOT 3 and 4 standards. Do not mix Castrol SRF and other brake fluids, as this will reduce the benefits of Castrol SRF. Sold in 33.8 ounce bottles.
