Rated 5 out of 5 by 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. September 14, 2016

Rated 5 out of 5 by 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. September 2, 2016
