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.

Works .pour 1 bottle to a quarter tank.. drive on freeway. Then fill up tank and drive about 150 to 200 highway miles.. keeps the code away for months.. add 91 octane to keep it off

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.

Help with rough idling on our 2014 Tahoe that had the CEL coming on. After using this product no more CEL or rough idling. The OBD code was showing bad oxygen sensor this solved our issue. Would recommend and will purchase again if needed, way more cheaper than replacement of sensors $$$$$
