HIGHTEC ZH-M SYNT

A fully synthetic central hydraulic fluid for level control, hydropneumatic suspension, and combined steering/brake assist systems on newer-generation vehicles — not a gearbox oil despite sitting alongside them in many parts catalogues, so it's worth double-checking your vehicle's exact fluid requirement before ordering.

Questions & answers

What is this fluid actually used for?

It's a central hydraulic fluid for self-levelling suspension, hydropneumatic suspension systems, and combined power steering/brake assistance — not a conventional manual or automatic gearbox oil, despite often being grouped with other transmission fluids.

How do I know if my car needs this fluid?

It's typically specified on vehicles with hydropneumatic or self-levelling suspension and shared hydraulic steering/brake assist circuits. Check your handbook or ask us to confirm before ordering, as using the wrong hydraulic fluid can affect these systems.

What temperature range is it rated for?

It's designed to perform from -40°C to +130°C, with good ageing resistance and low friction at low temperatures.
