Review: Works if you need help. Not a miracle in a bottle. - It has worked every time I've used this product. Won't fix a damage catalytic converter but will help you pass the test if your car almost passed.
Review: Worked like a charm. - Used it as directed. Down to an eighth of a tank. Poured it in and added enough gas to get back to one half a tank. Wanted to get it mixed in really well. Immediately jumped on the interstate and ran 75 MPH for 40 miles. Stopped and filled the tank and when I restarted the engine, the light was off. Coincidence? Not a chance. Light had been on continuously for weeks. AutoZone said I needed a catalytic converter. Nope. One thing I found out the hard way. If your gas filler has a flap at the top, make sure it is easy to push aside. Mine had a little release button near the top that the filler hose would depress before the flap would release. Dumped the first bottle right on the ground. Twelve bucks wasted. No one to blame but me, I guess. Still a bargain, even at twice the price.

## Questions & Answers

**Q: How do I get my money back it did not work**
A: I once submitted all the required paperwork for the money back and they never sent me a dime.  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.

### ⭐ Before use on March 15 two days later March 17 engine light still on
*by B***N on March 17, 2026*

I read the specs on this product and it was guaranteed to cleanse as well as turn engine light off in vehicle. I received it March 14.2026 and used it on March 15.2026 I took a picture on Sunday before I entered it into the gas tank engine light was on at that time. Today is March 17.2026 and engine light is still on. The truck was driven for one hour on the 15th 45 minutes on the 16th and 50 minutes on 17 March. Still the engine light is on. Got home parked the vehicle took a picture again to show engine light is still on product guaranteed it was shut it off, but unfortunately product does not work.
