Purpose and Specifications

LIQUI MOLY 20980 Central Hydraulic System Oil 2500 is a fully synthetic hydraulic oil designed for power steering, suspension level control, hydraulic brake boosters, and hydro-pneumatic systems. It meets key specs like LDS, PSA S71 2710, and Renault PSF Class 1, making it ideal for Peugeot, Citroen, and Renault vehicles.

This green-colored oil delivers maximum wear protection, excellent corrosion resistance, and superior thermal stability to keep your hydraulic systems running smoothly. Special ash-free additives prevent foaming under heavy loads, protect against premature aging, and ensure reliable performance in Arctic climates with a pour point as low as -45°C for easy cold starts and full function in freezing temps.

• 1-liter carton packaging for convenient use and storage.
• Outstanding low-temperature flow keeps steering responsive in winter.
• High thermal stability maintains thickness during hot operation, reducing wear.

When to Use / Replace?

Use LIQUI MOLY 20980 when your vehicle manual specifies LDS, PSA S71 2710, or Renault PSF Class 1 oils. Perfect for topping off or full flushes in central hydraulic systems. Replace every 60,000 km or 4 years, or sooner if fluid darkens, foams, or you notice noisy steering/hard suspension—whichever comes first. Shelf life is 5 years unopened in cool, dry storage.

Shake well before use and follow manufacturer instructions for best results. Works undiluted for optimum protection.
