FAQs
Is this compatible with DOT 3 fluid?
Yes, Carlube DOT 4 is generally compatible with DOT 3 systems, but always verify your vehicle owner's manual before mixing fluids.
Can I use this in my Citroen?
No. Certain Citroen models utilize specialized mineral oil-based systems which are incompatible with this synthetic fluid.
How often should I change my brake fluid?
Most manufacturers recommend replacing brake fluid every 2 years or 24,000 miles, or as specified in your vehicle service manual.
What happens if moisture gets into the fluid?
Moisture lowers the boiling point of the fluid, which can lead to vapor lock and reduced braking performance during heavy use.
Can I use this for my motorcycle?
Yes, this fluid is suitable for most motorcycle hydraulic brake systems that specify DOT 4 fluid.
Troubleshooting
Spilled fluid on vehicle paint
Immediately rinse the area with large amounts of water to neutralize and remove the chemical before it eats through the clear coat.
Spongey pedal feel after flush
This typically indicates air is trapped in the hydraulic lines. Re-bleed the system starting from the wheel furthest from the master cylinder.

Setup, Compatibility & Care
Before use, consult your vehicle handbook to confirm that your braking system requires DOT 4 fluid. This product is generally compatible with other DOT 3 and DOT 4 fluids but is not intended for systems requiring mineral oil (commonly found in specific older Rolls Royce, Citroen, or Jaguar models). When handling the fluid, use a funnel to avoid spills. If any fluid drips onto the bodywork, rinse the area immediately with copious amounts of water, as the synthetic chemicals can permanently mar automotive paint. Store in a cool, dry place with the cap tightly secured to prevent moisture ingress.
