Purpose and Specifications

RAVENOL PSF 1L is a fully synthetic power steering fluid that delivers smooth, reliable steering in vehicles from Citroën, Peugeot, Honda, Kia, Mazda, Mitsubishi, Subaru, and Toyota. It matches exact specs like CITROËN/PEUGEOT 9735EJ, HONDA PSF-S, KIA PSF-III, MAZDA PSF, MITSUBISHI DIAMOND PSF-2M, SUBARU PS FLUID, and TOYOTA PSF-EH, ensuring optimized power transmission and long-lasting performance.

This high-quality fluid excels in extreme conditions, flowing easily down to -48°C for crisp steering in freezing winters, while staying stable up to 211°C flash point to prevent breakdowns in hot summers. It provides excellent wear protection, stops foam buildup for quiet operation, and protects seals and metals from corrosion, extending steering system life up to 100,000 km or 5 years with proper maintenance.

• Smooth steering feel with reduced effort, even at low speeds
• Prevents pump wear and leaks for fewer repairs
• Stable performance across -40°C to 150°C operating temps
• Shelf life of 5 years unopened in cool, dry storage

When to Use / Replace?

Use RAVENOL PSF 1L during power steering flushes or top-ups in compatible models to restore like-new responsiveness. Replace every 50,000-80,000 km or 3-4 years, or sooner if steering feels heavy, noisy, or jerky. Ideal for electro-hydraulic systems in modern cars needing low-temp flow and high-heat stability.

Avoid mixing with ATF or generic fluids, as this can damage pumps quickly—flush completely for best results. Perfect for daily drivers and performance vehicles demanding precise control.
