Works like a supplement
If you use it and see a difference, you will blame it on this cleaner, if not, you will say the product does not work. Exactly like your weight loss supplements! Who knows what this stuff does, but it may do something. Or maybe it does not.

Used to clean an O2 sensor
Seems to have resolved an issue with a wavering idle for my 89 Mercedes 300e with 468,000 miles.

2014 Ford Edge SEL
Worked like a charm! Used as directed, it cleared the P0420 & P0430 codes that were coming up on my OBD II scanner after a complete engine swap. Definitely recommend this product.
