Review: Ran 1 bottle added to 1/2 tank gas in Subaru Outback with 214K miles, vastly improved performance followed by 2nd bottle added to 1/2 tank and it did not seem to improve past just 1 bottle. Did not make ODB2 lights go off. fast delivery, good value, and I will buy again.
Review: I have used it twice on my 25 year old car and it helped my car pass my state's emissions tests. Before the treatment, my car had a blast of white smoke coming out of the muffler and once I started using it the smoke was virtually gone.
