Not all power steering fluids are....

Not all power steering fluids are created equal. During extensive lab and on-car testing CARDONE engineers learned that there are many substandard power steering fluid brands on the market that lack the additives necessary for proper lubrication of the pump. More specifically additives such as viscosity improvers, friction modifiers and anti-foaming agents are not present. Use of a substandard fluid eventually causes the steering system to overheat and the pump bushing to break down. At this point the pump no longer holds pressure which results in a total loss of assist. In fact during the testing process pump failure due to substandard fluid was recorded in as little as 20-30 minutes after installation!
