Follow the vehicle manufacturer's recommendations. If no specific advice is given, change it every 2 years.
While it is compatible with DOT 3 and DOT 4 fluids, mixing is not recommended to maintain its superior performance.
Rinse the affected area with water immediately.
Store in a cool, dry place away from direct sunlight and heat sources.
It is suitable for most vehicles, but it is not suitable for braking systems that require mineral oil.
Synthetic brake fluids offer enhanced protection against corrosion and wear, and a higher boiling point for improved braking performance.
Vapor lock occurs when brake fluid boils, creating gas bubbles that reduce braking efficiency. Castrol DOT 4 has a high boiling point, which helps prevent vapor lock.
Rinse immediately with water.
Check for air in the brake lines; bleed the brakes.
Check brake fluid level and consider replacing if old.
Consult vehicle manual to confirm compatibility with DOT4 fluid.
Inspect brake lines and connections for leaks; repair or replace as necessary.
Castrol Brake Fluid DOT 4 is designed for use in all conventional brake systems. Before use, ensure the fluid meets the vehicle manufacturer's specifications.
Compatibility: This fluid is compatible with other fluids meeting FMVSS 116 DOT3 and DOT4, however, for optimal performance avoid mixing. Care: Handle with caution. If spilled on painted surfaces, rinse immediately with water to prevent damage. Dispose of used brake fluid according to local regulations.
Important: This fluid is not suitable for systems that require mineral oil-based fluids, such as certain Citroen systems (where Castrol LHM plus is suitable) or Rolls Royce vehicles (for which Castrol CHSMO Plus is approved). Always consult your vehicle's manual.
