Prestone Power Steering Fluid

Prestone Power Steering Fluid: Engineered Protection for Every System

When it comes to keeping your steering rack, pump, and hoses in top working order, the fluid circulating through the system matters more than most drivers realize. Prestone has built a reputation over nearly a century as one of America's most trusted automotive fluid brands, and their lineup of power steering fluids reflects that same commitment to chemistry-backed protection. Whether you drive a domestic truck, a European sedan, or an Asian-market import, Prestone offers a targeted formulation engineered to match your vehicle's specific hydraulic requirements.

Anti-Wear System Protection – The Core Technology

Every Prestone power steering fluid is built around what the brand calls its Anti-Wear System Protection technology. Designed with this Anti-Wear System Protection, Prestone PSF protects against pump failure, squeals, and clogs — three of the most common and costly power steering complaints. Beyond the additive package itself, the formula contains several key ingredients to ensure smooth system operation: anti-wear agents to protect pump components, antioxidants to prevent sludge formation, seal conditioners to protect and rejuvenate seals, anti-foam agents to prevent pump cavitation and steering loss, corrosion inhibitors to protect metal components, and pour point depressants for good steering even in low temperatures.

A Full Lineup for Every Vehicle Type

One of the defining strengths of Prestone's power steering fluid range is how thoroughly it covers different vehicle platforms. Their standard formula is a versatile, universal fluid with a 50,000-mile fluid life, formulated for use in all manufacturers' cars, SUVs, crossovers, and light and medium duty trucks. It is compatible with factory fluids and meets service requirements of GM, Ford, Chrysler, and many global manufacturers.

For drivers who want extended service intervals, Prestone offers dedicated vehicle-specific synthetic fluids — including formulations specifically for American, European, and Asian vehicles. These synthetic fluids are designed with 2X Anti-Wear System Protection and deliver a 100,000-mile fluid life, which is 2X more than conventional fluid, extending the time between replacement.

Power Steering Fluid + Stop Leak

Prestone also addresses one of the most frustrating power steering problems — slow seeping leaks — with a dedicated combination product. Prestone Power Steering Fluid + Stop Leak delivers increased system life, both preventing and stopping system leaks, with Stop Leak additives that renew, restore, and condition seals in the power steering system. Available in 12 oz. (AS262) and 32 oz. (AS263) sizes, it mixes with all approved power steering fluid and meets requirements for GM, Ford, Chrysler, AMC, and most foreign cars.
