Purpose and Specifications

Motul DOT 3 & 4 is a fully synthetic brake and clutch fluid designed for all hydraulically actuated brake and clutch systems. This polyglycol-based fluid meets both DOT 3 and DOT 4 manufacturer requirements, making it compatible with virtually all modern vehicles.

Key Performance Specs:

• Dry boiling point: 245°C (473°F) – exceeds DOT 3 and DOT 4 minimum standards
• Wet boiling point: 160°C (320°F) – allows extended use between replacements
• 100% synthetic formula with superior thermal stability
• Corrosion-resistant and neutral to all brake system seals
• Compatible with DOT 3, DOT 4, and DOT 5.1 fluids (do not mix with mineral-based fluids)

When to Use / Replace?

Replace your brake fluid every 12 to 24 months, depending on your vehicle manufacturer's recommendation. Do not simply top up – always perform a complete fluid replacement for safety. The high wet boiling point of this fluid means it resists moisture absorption better than conventional options, extending the time between replacements.

Operating Conditions: This fluid maintains effective braking performance even under extreme conditions, including high-temperature driving, heavy braking, and challenging weather. The superior boiling points prevent vapor lock, ensuring consistent brake response when you need it most.

Frequently Asked Questions

• Can I mix Motul DOT 3 & 4 with other brake fluids? Yes, it is fully compatible with DOT 3, DOT 4, and DOT 5.1 non-silicone fluids. Never mix with mineral-based fluids like LHM.
• How should I store this product? Keep the bottle tightly sealed in its original container to prevent moisture absorption. Brake fluid absorbs water over time, which reduces its boiling point and braking performance.
• Is this fluid suitable for my car? If your vehicle manufacturer specifies DOT 3 or DOT 4 brake fluid, this product is approved for use. Check your owner's manual or service documentation to confirm.
