Purpose and Specifications

Eurolub ZH-L ST Hydraulik-Fluid is a premium green hydraulic fluid specially developed for central hydraulic systems, power steering, convertible top activation, and hydropneumatic chassis with shock absorbers. It ensures smooth steering, reliable roof operation, and stable suspension performance by staying fluid in cold starts and thick enough under heat to protect seals and pumps.

• Operates safely from 30°C to 60°C for everyday driving, with max tolerance up to 82°C before risking seal damage or viscosity loss.
• Provides long-lasting lubrication to prevent wear in high-pressure systems.
• Shelf life of 3-5 years when stored properly in a cool, dry place.

When to Use / Replace?

Use this fluid in vehicles with combined hydraulic systems like power steering and suspension. Replace every 50,000 km or 2 years, or sooner if fluid darkens, smells burnt, or you notice noisy steering/pump whine. Check levels monthly and top up to avoid air entry that causes overheating.

Practical Benefits: Keeps steering light and responsive in all weather, extends pump life, and avoids costly repairs from overheating or contamination.

Q: What temperature range is safe for this fluid?
A: Ideal 30-60°C; avoid exceeding 82°C to prevent seal hardening and fluid breakdown.

Q: How often should I change it?
A: Every 50,000 km or 24 months under normal use; inspect yearly for contamination.

Q: Is it compatible with my car's systems?
A: Yes, for central hydraulics in European cars with servo steering and hydropneumatic suspension; always check your manual.
