Purchased yesterday and put bot cans in my gas tank. Very pleased with how it works. Had a code P0175 02 sensor bank 2. Thought I had to replace the sensors but looked into products and read the reviews of these can. Check engine light went off this morning. Drove it aggressively after I used the cans and they worked as advertised. Highly recommend.

car performance improvement

I bought this to use in my 2021 chevrolet equinox when my check engine light came on with an exhaust issue. so far I believe it's working. I have noticed increased mileage and a little more "zip" in the engine.

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.
