Pentosin CHF 11S Power Steering Hydraulic Oil (2 x 1L) - OEM

In this review the Pentosin CHF 11S two-pack is assessed as a direct, practical replacement fluid for vehicles that require a specific synthetic hydraulic oil. The bottom line: technicians and owners seeking an OEM equivalent replacement will appreciate that this set lists multiple equivalent part numbers and is packaged as two 1-liter bottles, making top-ups and small-system refills straightforward. The review focuses on build quality, compatibility signals from the provided equivalent numbers, and customer feedback about value and occasional leakage reports.

Key Features

• OEM equivalent part numbers: Includes listed equivalents such as JLM21112, Q1320001 and 88901975 so buyers can match service manuals and parts guides with confidence.
• Two 1L bottles: Supplied as a 2 x 1L set which is convenient for systems that need less than a full large container and for keeping a spare for future top-ups.
• Synthetic hydraulic formulation: Designed for compatibility with power steering and hydraulic systems that call for CHF 11S grade performance.
• Easy identification: The published part number 1405116-Set2 makes it straightforward to confirm ordering and inventory for workshops and DIY customers.
• Value proposition: Customers frequently cite good value for money, making this a cost-effective option for routine maintenance.

Who It's For

This product is best suited for mechanics, independent workshops and vehicle owners who need a reliable synthetic hydraulic oil that matches common OEM reference numbers. It is especially useful for those maintaining European cars where CHF 11S specification fluids are specified, and for anyone who prefers buying a two-bottle set to handle initial fill plus a spare for future servicing.

Those who should look elsewhere include owners of vehicles that require a different hydraulic fluid specification or proprietary brand-only lubricants not compatible with CHF 11S. Buyers worried about bottle sealing or large-volume professional shops that consume fluid by the case may prefer larger commercial containers from industrial suppliers.

Pros & Cons

Pros

• Two 1L bottles make topping up and small-system service convenient without waste.

Cons

• Some customer feedback mentions leakage concerns, so check bottle seals and fittings during installation.
• Limited to small-volume supply; not ideal for high-volume shop use without multiple sets.
