I bought a Saturn SC2 w/ 112,000 for my daughters. I thought the engine felt weak so checked the compression which was at 120 lbs. New it would be at 190. After some research I came across Auto-Rx. I did the engine treatment and the compression came up to 180 lbs.
My father bought a Ford Windstar w/ 90,000 miles and thought the engine oil looked too dirty. I had told him about Auto-Rx so he did the engine treatment and now makes 2 mpg better than before.
I have a friend that has a Chevy Lumina w/ 190,000 miles. Her transmission was slipping so bad she was afraid to cross intersections. I added Auto-Rx to the tranny and after 2,500 miles it is shifting normally.
I have family, friends, and co-workers using the product now because of these results.
