If you love the quick and smooth way you can steer your vehicle, you need to make sure that your power steering fluid is full and in good condition. This fluid level can drop, but it rarely drops much. You can generally check the level of the fluid by simply looking at the reservoir. If it is looking low, it's a good idea to take your car in for a check, to make sure there's not a leak. While this fluid rarely needs to be replaced, you may want to consider talking to your mechanic about replacement of the fluid somewhere between 50,000-100,000 miles.
Keeping your car working as long as possible means keeping up on the maintenance. One of the most important things you can do for your car is to ensure that all fluids are topped off, clean, and not leaking.
