This green fluid ensures smooth, responsive steering and reliable hydraulic performance in everyday driving.

It delivers practical benefits like effortless power steering that feels precise even in tight turns, quiet operation without whining noises, and protection for hydraulic components against wear during hot summer drives or cold winter starts. Works effectively in operating temperatures from -30°C to 130°C, keeping fluid flowing smoothly in extreme weather.

• Long-lasting protection: Shields pumps and valves from premature failure
• Versatile use: Ideal for European cars with combined hydraulic systems

When to Use / Replace?

Use this fluid for top performance in vehicles requiring ZF or similar hydraulic specs. Replace every 60,000 km or 4 years to maintain peak steering feel and prevent leaks or stiff handling. Shelf life is 5 years when stored in a cool, dry place between 0°C and 25°C away from direct sunlight.

Check fluid level monthly and top up if low. Signs to replace include hard steering, unusual pump noise, or discolored fluid.
