The power steering on my Grand Am was making all kinds of noise and was so tight that it was almost manual steering instead of power. A mechanic told me that it would be $400-$500 to fix. Before I would spend that much money I decided to try Lucas. I bought two bottles of stop leak, drained the power steering, added one bottle and topped it off with regular power steering fluid and drove it around the block a couple of times. The problems almost immediately went away. I let the car sit overnight and the next day I repeated the above process. Several thousand miles later the car is still driving BETTER than new. Once again Lucas has saved me several hundred dollars.
