I did see slight lowering of some numbers but very little. Basically buy it but don’t expect to actually get a refund much less twice the amount **Q: Does this clean oxygen sensors and catalytic converter?** A: This product cleans out just about everything totally from the gas tank to the exhaust tailpipe. Severely clogged systems may require a second treatment but anyone that lets it get to that point is probably going to need a lot more than an oil change and a few spark plugs. **Q: Does it have to be done right before the test or a week before is okay?** A: i've done it 4 days before testing...and this is if you're failing due to a worn out cat converter; if you're not passing due to HC, that is a tune up and maybe new O2 sensor... **Q: Will this help with the egg smell I get once in a while after I floor it. Doesn't stink all the time only once in a while** A: Yes, it will. The "rotten egg" smell is unburned fuel passing through your car due to dirty injectors, dirty intake valves, dirty compression chambers, dirty catalytic converts and dirty EGR valve & passageways, and dirty spark plug tips. This product cleans all of these areas. ## Customer Reviews ### ⭐⭐⭐⭐⭐ P0 420 check engine lite on? *by R***N on 19 April 2026* A fruend called me anout her MIL/Enginel light coming on.
