Works for us!
We use this regularly in my car. Seems to help keep sensors clear. My engine light comes on if I don’t add. We add it to gas tank. My husband says it’s because of poor quality (dirty) gas from other countries.

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.
