Long life fluid:
MOTUL DOT 5.1 high wet boiling point (185°C / 365°F) is superior than the requirements of the standards DOT 3 (140°C mini / 284°F mini), DOT 4 (155°C mini / 311°F mini) and DOT 5.1 (180°C mini / 356°F mini), and therefore enables longer use of this product.
Indeed, DOT 3, DOT 4 or DOT 5.1 brake fluids have the property of absorbing moisture from the air, which reduces their boiling points and therefore braking safety.
The wet boiling point is measured after moistening the product with 3% water in order to be representative of the state of the fluid after 1 year of use.
Perfectly neutral with seals used in braking systems. Anti-corrosion.

Specially designed for anti-locking brake systems (ABS):
The viscosity at cold temperature (820 mm²/s at -40°C / -40°F) of MOTUL DOT 5.1 is lower than DOT 4 (up to 1800 mm²/s) and DOT 3 (up to 1500 mm²/s) brake fluid specifications and allows easier fluid circulation and flow through the micro-valves of anti-locking systems for better response of ABS and other electronic stability programs (ESP, ASR,...) requiring quick brake systems actuation.
