Rated 5 out of 5 by from IT WORKS I had a leak in power steering pump for a long time. It got to the point that I was adding fluid every 2-3 days. This was recommended to me, and since I added it to my system, I've not had to replace any more fluid. Its been a few weeks now.

Rated 5 out of 5 by from Does what it says! I started using this on a recommendation from a mechanic I used. Since then I have used it in three vehicles all with very good results. I have been using it on my 2002 Honda Odyssey for about 30,000 miles and have had no more leaks or steering issues. I like this product.

Rated 1 out of 5 by from FOR LUCAS PRODUCT-VERY DISAPOINTING 2nd time I have used product and both times only used part of the bottle and it made the problem worse than the original problem.1st time in a caddy-it made the steering so tight (even after flushing and putting a re-built/re-man steering box on vehicle) that you could not steer at all !! Second time in a ford Escape with the same results,plus it blew out the power steering pump !!!

Rated 4 out of 5 by from THis product works great. It stays in my system up to 2 weeks longer during a leak than just the regular fluid alone.

Rated 5 out of 5 by from Instant miracle!! My Vette has had morning sickness for years. I replaced equal amount of power steering fluid with (1) bottle of Lucas stop-leak. It cured the problem instantly. Finally, no more hard erratic steering!

Rated 5 out of 5 by from Power Steer me in the right direction FORD Contour 1996 SE with 151,000 miles. Noticed a leak by the driver's side tire. Oh no! Type of fluid , location and internet forums pointed to a costly power-steering rack replacement. "But wait!" (They all said) "Try LUCAS first!" I did and I am glad i did! It took about a week's worth of driving (50 miles) but the leak has completely stopped. This product is a God-send!
