Vehicle Repairs. We've Got What It Takes.
The febi range of high-quality, specialist hydraulic oils provide optimised low-temperature performance. They are based on advanced additives and selected mineral base oils, and are developed specifically for use in central hydraulic systems such as power steering, convertible roof mechanisms and hydro-pneumatic suspension systems.

Quality by Conviction:
Oils from febi are not universal products, but rather are tailored to the special requirements of vehicle manufacturers. Only the right oil can guarantee the safe functioning of the hydraulic systems in the vehicle. High-quality hydraulic fluids from febi are therefore precisely matched to the special requirements of vehicle manufacturers.

About Power Steering Oil

Power Steering Fluid for Porsche - Steering System Performance & Protection

Power Steering Fluid is essential for maintaining smooth, responsive steering performance in Porsche vehicles. Designed to operate under high pressure and temperature, power steering fluid lubricates internal components, transmits hydraulic force, and protects the steering system from wear and corrosion.

Available from Design911, Porsche-compatible power steering fluids help ensure precise steering feel, quiet operation, and long-term reliability across both modern and classic models.

What Does Power Steering Fluid Do?

Power steering fluid supports the hydraulic steering system’s performance and durability.

Core Functions:

  • Transmit hydraulic pressure for assisted steering.
  • Lubricate pumps, racks, and seals.
  • Reduce friction and internal wear.
  • Protect against corrosion and contamination.
  • Maintain consistent steering feel and response.

Using the correct power steering fluid specification is critical for system efficiency and component life.

Why Does Power Steering Fluid Fail?

Power steering fluid degrades over time due to heat, pressure, and contamination.

Common Causes of Failure:

  • Thermal breakdown from sustained high operating temperatures.
  • Contamination from moisture, debris, or metal particles.
  • Fluid oxidation and additive depletion.
  • Leaks allowing air and contaminants into the system.
  • Extended service intervals beyond manufacturer guidance.

Degraded fluid can cause noisy pumps, heavy steering, and premature component wear.

When Should Power Steering Fluid Be Replaced?

Regular fluid replacement helps maintain steering performance and reliability.

Replacement Is Recommended When:

  • Manufacturer service intervals are reached.
  • Steering becomes noisy, heavy, or inconsistent.
  • Fluid appears dark, burnt, or contaminated.
  • Power steering components are repaired or replaced.
  • Preventative maintenance is being carried out.

Performance-driven or track-used vehicles may require more frequent fluid changes.

Key Benefits

  • Maintains smooth and precise steering response
  • Reduces pump and rack wear
  • Protects seals and hydraulic components
  • Supports quiet and reliable steering operation
  • Suitable for modern and classic Porsche models
