Generally, BMW recommends using a specific type of power steering fluid that meets the BMW specifications. These specifications ensure that the fluid provides the necessary lubrication and protection for the power steering system components and maintains the system's optimal performance.
The recommended power steering fluid for BMWs is typically a mineral-based fluid with certain additives. It is usually labeled as "BMW Power Steering Fluid" or "BMW PSF." Using a non-recommended fluid can compromise the performance and durability of the power steering system and possibly void the vehicle's warranty.
If you are unsure about the correct power steering fluid for your BMW, it is best to consult your vehicle's owner's manual or contact an authorized BMW dealership or a qualified mechanic. They can provide the precise information based on your vehicle's specifications.
