Red Line 30409 Synthetic Power Steering Fluid - 946ml

High-performance Red Line hydraulic fluid for suitable conventional power-assisted steering systems requiring one of the supported power-steering fluid or ATF specifications.

Red Line Power Steering Fluid is formulated to provide improved wear protection, consistent pump performance and excellent resistance to thermal breakdown, evaporation and foaming under demanding road, performance and motorsport conditions.

Its relatively lightweight formulation helps minimise parasitic power losses while maintaining strong high-temperature viscosity. Red Line states that the fluid helps prevent steering fade at elevated temperatures and excessive steering effort during cold operation.

The fluid is compatible with petroleum-based and synthetic power-steering fluids and satisfies the service-fill requirements of many manufacturers, including Mazda, where the appropriate supported specification is required.

Fitment advice: Use only in hydraulic power-steering systems requiring one of the specifications supported by Red Line. Red Line specifically lists Mazda among the manufacturers whose conventional power-steering service-fill requirements may be satisfied by this product. Always follow the vehicle manufacturer's specified fluid requirement.

Important application note: This product is intended for hydraulic power-steering systems. Vehicles equipped solely with electric power-assisted steering do not use conventional power-steering fluid.

Other items to consider: When servicing a hydraulic steering system, you may also want to inspect the power-steering reservoir, hoses, pipework, pump, rack seals and drive belt where applicable.

Useful tools / consumables: Fluid extractor or syringe, drain container, filling funnel, protective gloves and workshop towels. A suitable hose-disconnection method may be required for a complete system flush.

Difficulty guide: DIY Difficulty: Easy to Moderate. Reservoir fluid replacement is generally straightforward, while a complete system flush requires additional care to avoid introducing air into the hydraulic system.

Why Red Line? Red Line Synthetic Oil is known for high-performance lubricants, fluids and additives developed for demanding road, track and motorsport use. Red Line products are chosen by enthusiasts and workshops for their focus on protection, thermal stability, friction control and application-specific performance.

What’s in the bottle: One 946ml / 1 US quart bottle of Red Line Synthetic Power Steering Fluid.

Service notes: Follow the vehicle manufacturer's procedure when draining, flushing or topping up the hydraulic steering system. Avoid overfilling the reservoir and ensure the system is correctly bled after any work that introduces air into the hydraulic circuit.
