I currently use your fuel treatment and oil stabilizer and this was icing on the cake.

I wanted to tell you a story about a problem I was having with my 1992 Honda Accord. I started hearing a whining sound when I would turn corners in both directions from my rack and pinion. Also I noticed I started having a leaky seal at the rack and pinion. My pump went bad and I replaced it but still had the whining noise. I tried your power steering treatment and immediately had no noise. I just wanted to let you know I was highly inmpresed with your product and I will always continue to use it for all applications. I currently use your fuel treatment and oil stabilizer and this was icing on the cake. Your product does what it says it does and I have passed what I know to everyone I know. I work part time at a parts store and I reccommend all your products to customers. Thank you for making such a great product.
