    Miracle Juice

    Hi Guys - I wanted to tell my story…I had recently used your Catalytic cleaner in my 2009 Chevy Colbalt because the oxygen sensor light came on. I took it in to my mechanic and he said I needed to replace the Catalytic Converter…a $700 repair bill! I went to my local auto parts store and decided to try your product. It was even on sale, so that was nice! Within two days, the oxygen sensor light turned off. Amazing! I also purchased more product for my 2004 Chevy Cavalier. The light just came on in that one, too! I didn’t even take it to my mechanic…just put in some more ‘miracle juice’ Review by Bob W. • (Posted on 9/1/2017)
