Here are reasons why your car’s power steering fluid can go bad:


The components of the power steering system such as the inside of hoses, bearings, seals or gaskets may deposit tiny particles in the fluid which results in contamination. The normal breakdown of the rubber parts used in the system or components wearing against each other can deposit these particles in the fluid, turning it a darker color.

The tiny particles in the power steering fluid can speed up wear of other parts and result in clogs. Checking the color of the fluid is one way to see whether it is contaminated. If it is contaminated, contact your auto technician expert to perform a power steering fluid flush. This process helps to renew the fluid and keep things working normally.


Power steering fluid can breakdown over time apart from getting contaminated. It is a hydraulic fluid that contains additives to hold the integrity of the oil, maintain viscosity, and prevent foaming. Over time, these additives lose their efficiency which makes the fluid very thin and allows foaming. This speeds up wear in your steering system and, as a result, the fluid will need to be replaced. You can avoid replacing the expensive power steering components by having the fluid changed at regular intervals.

You may renew the power steering fluid of your car every 75,000 miles or after 2 years if you do not drive in severe conditions. Severe conditions could include driving off-road, in heavy, stop-and-go traffic or in temperatures beyond 100 degrees. However, it is recommended to renew the fluid every 30,000 miles.
