MAG1 power steering fluid (12 oz) is a hydraulic fluid formulated to lubricate and protect components of a vehicle's power steering system. It supports consistent hydraulic pressure, reduces wear on pumps and seals, minimizes foaming, and helps maintain responsive steering performance across varied temperatures. The 12 oz size is ideal for topping off the reservoir, small maintenance tasks, or keeping as an emergency spare. Always check your vehicle manufacturer's specifications before use, store in a cool dry place, and dispose of used fluid in accordance with local regulations.
