The Best Power Steering Fluids

Understanding Power Steering Fluid Types

Power steering fluids are not interchangeable. The most common types are:

• Conventional (ATF-based): Often found in older vehicles, these typically use automatic transmission fluid as a base. Check your owner's manual to confirm if your car uses this type.
• Universal/Multi-Vehicle: These are designed to be compatible with a wide range of vehicles, often specified by the manufacturer. They are a good choice if you're unsure or have multiple vehicles of different makes.
• Imported Vehicle Fluids: Some European and Asian manufacturers specify unique fluid formulations. Using the wrong fluid in these vehicles can cause significant damage.

Key Fluid Specifications to Consider

Always consult your vehicle's owner's manual for the exact specifications required. Key terms to look for include:

• Dexron and Mercon: These are common specifications, particularly for American and some imported vehicles.
• CHF (Central Hydraulic Fluid): Often specified for European vehicles, particularly those from Germany.
• Manufacturer-Specific Codes: Many brands have their own proprietary fluid codes (e.g., Honda PSF, Subaru PS Fluid).

Always prioritize the fluid recommended by your car's manufacturer to ensure compatibility and prevent potential damage to the steering system. Using the wrong fluid can lead to leaks, pump failure, or stiff steering.
