I have used and promoted Prolong since I saw your infomercial, before you could even buy it in stores. I’ve been extremely happy with all your products. I could tell you about things that impressed me like after 25,000 miles with Prolong Transmission Treatment, I took it to my mechanic to change the filter and transmission fluid. He said that in all the time he has changed the fluid with me using the product there has never been any fine grindings in the pan, which to me means no wear.
