24-hour Hotline:

4006 939 808

Performance Features:

Low-viscosity, swift response: at –40°C, it outperforms conventional DOT 4, delivering a more responsive cold‑start performance.
High resistance to air‑induced brake fade: effectively prevents brake softening or failure under conditions such as long downhill grades and aggressive driving.
Corrosion‑Resistance and Seal Compatibility: Protects metal components, is compatible with a wide range of rubber seals, and prevents seizing and blockages.

Technical Specifications:

Dry equilibrium boiling point: ≥230°C (meets and exceeds the GB 12981-2012 HZY4 national standard, effectively preventing high‑temperature brake fade)
Wet equilibrium boiling point: ≥165°C (retains a high boiling point even after absorbing moisture, with no degradation in braking performance)
Low-temperature kinematic viscosity: ≤750 mm²/s at −40°C (faster brake response)
Fully compatible: Supports fuel‑powered, hybrid, and select new‑energy vehicles equipped with braking systems such as ABS, ESP, DSC, and EBD.
Compatibility: Backward compatible with D0T3/HZY3.
Replacement interval: 2 years or 40,000 km, whichever comes first.
Applicable Standard: GB 12981-2012 HZY4
Shelf life: 4 years

Warning:

Brake fluid can corrode painted surfaces; if it is accidentally splashed, rinse immediately with water.
Protect against contact with skin and eyes; if contact occurs, rinse immediately with clean water and seek medical attention.
Store only in the original sealed container to prevent moisture absorption. Use promptly after opening.
Please dispose of used brake fluid in accordance with environmental regulations and deliver it to a designated recycling facility for proper treatment.

Xiao Han on Lubrication—Mixing Old and New Motor Oil? The Consequences Can Be Severe.

Some car owners, when they find their engine oil is low, top it up by mixing in leftover oil of different brands and viscosities, assuming, “It’s all engine oil—mixing them shouldn’t be a problem.” This notion is profoundly mistaken. Mixing oils with different formulations and base stocks can trigger a cascade of adverse reactions, which, in severe cases, can even lead to complete engine failure. Today, we’ll discuss the dangers of blending oils and the proper way to handle this issue.
