Maxima Racing Oils - Automotive 89-01901: Oils, Fluids & Sealer, 32oz, Synthetic Power Steering Fluid - Maxima Oil SYN PSF power steering fluid is a high performance oil engineered to perform under the severe stresses found in modern-day racing power steering systems. Racing power steering systems operate under increased loads and elevated temperatures when compared to on-highway systems. SYN PSF uses technologically advanced additives to prevent wear, thermal breakdown, and oxidation--offering unsurpassed protection to pumps, cylinders, valves, and gears. Special conditioners keep seals and O-rings pliable under extreme conditions. SYN PSF offers smooth, quiet, trouble-free operation. The full-synthetic formula delivers consistent steering response and exhibits excellent flow at low temperatures. This lightweight formula reduces initial drag on pump, avoiding power losses. High-viscosity index fluid offers greater high-temp viscosity than many petroleum-based fluids. Advanced ester-based synthetics eliminate fading and boil-over and exhibit exceptional antifoam characteristics in high performance, high-temperature environments.
