Catalytic converter cleaner passes emission tests to maintain catalytic efficiency Oxygen sensor and combustion chamber cleaner, safe fuel additives

It's worked. Give it little time

Took around 2-3 days but did get the check engine light off.

So I poured the cleaner into my empty tank, then filled it up all the way with gas, so of course my check engine light is on with 3 codes about one of the o2 sensors having a slow response, so after I fill her up I went home, drove to work the next morning, 27 minute drive and the check engine light was still on, and my eco mode was not working, so on my way home from work, the check engine light was now gone and the eco was on for the ride home, so I will give 2 thumbs up for this product.

Wasn't sure if this would work or not. Engine light on due to catalytic converter/O2 sensor issue according to trouble code. Poured it into tank. 100 kms later engine light went off. Cheapest auto repair I've ever had. Will definately buy again if trouble code comes back.

It works but, if the the converter is clogged bad, it’ll break up the particles and shoot it all over the O2 sensor. It may take more than one bottle but it works. Notable increase in performance….right before a jig saw. ☺️
