No, different types of power steering fluid should not be mixed.
Power steering fluids can vary in formulation, including mineral-based and fully synthetic options. These fluids are designed with specific additives and properties, and combining different types may reduce performance or create issues within the power steering system.
For the best results, always use the fluid type specified by your vehicle manufacturer. If you are switching fluid types, we recommend completely draining and flushing the system before adding the new fluid.
