This did allow a P0420 code to stay off for about four months when instructions for use were followed precisely...this is very important. Note cataclean also wants you to use a bottle about every 3-4 months...\nBe sure to verify these instructions on the bottle and read carefully, as you never know when instructions might change from a posted review. I did follow these exactly, as it is not "fill and go"...you have to watch your gas level.\nFirst, I cleared the code with an automotive diagnostic scan tool.\nThen, I added the bottle of cataclean to a 1/4 full fuel tank\nDrove for about 14-15 miles\nRefilled the entire tank\nDrove til the tank was down to 1/8 full, and refueled.\n\nThe code stayed off for those four months of driving. \n\nThis is probably not a permanent solution for anyone, but does seem to be an effective product when used exactly as directed. I have an older car with a 2.4L GM Ecotech engine (and 134000 miles), which is notorious for oil blow by the piston rings, so I suspect there is slow oil byproduct combustion contamination of the catalytic converter. Since that can't be fixed without a major engine overhaul on an old engine, Cataclean is a lot more cost effective, and does seem to bring the emissions system up to operating efficiency.

Reviewed on www.walmart.com·DD
First time user of this product. 16 year old Chevy truck with 206,000 miles 5.3 V8. I've used Seafoam fuel treatment regularly over those 16 years but never anything focused on catalytic converter cleaning. The truck wasn't throwing any check engine lights nor was it experiencing any noticeable sluggishness prior to using this product so I can't necessarily say I've noticed any increased performance since. Fuel economy seems to be exactly the same and the engine sounds the same as it always does. I purchased this off the recommendation of a friend with a high mileage truck that claimed to experience a big increase in engine performance as he was having sluggish and poor running issues along with a noticeable increase in his fuel economy, saying it was more like the MPG he had when it was new vs the decreased mileage he'd had for a while. Anyway, I won't say this didn't do anything productive, I'm sure it cleaned something down the line. I will, in my opinion, say this stuff is quite overpriced. Now, had I been experiencing issues and other products failed to remedy and this product was successful, the price would be considered reasonable and on par with similar fuel additive offerings. For me, I'll stick the the seven or eight dollar can of Seafoam once or twice over an oil change period. My regular use of that appears to have me running just fine for a lot less.

Reviewed on www.walmart.com·Ed
I used Cataclean before and, previously, it did clear out the "Check Engine" light on my dashboard and that was about a year ago. We are now about 300 miles since I added this to my fuel tank at below a quarter tank, and although my car does run smoother, my check engine light is still on. Based on the smoother sound of my engine I believe the product works well but I do wish it turned off my check engine light as it did last time for a catalytic converter engine code.

Not Bad.
Reviewed on www.carid.com·Hunter Jeffrey
The build quality was nice, love how clean it came but the rear bumper had a small crack on it but I’m not complaining about it. This kit was well delivered and somewhat cared for *back bumper small crack*. Everything was in one box, I was told I would possibly come separate but since it was ONE whole item it came in one whole box. Haven’t put it on my Camry yet but a test look had me satisfied.

Reviewed on www.walmart.com·Bren29
My check engine light was on in my 2011 Honda CRV. It's the same thing as last year. Last year, I used one dose of this and got it through inspection. This year, it took two doses. I was about to give up and prepared to get robbed at the dealership when suddenly, the light went off. I took it directly to the inspection shop. I first started using this product after watching YouTube videos. I think the key to this stuff is to get on the Thruway or someplace where you can get the RPMs up high to clean the catalytic converter out. I drove it like the cops were chasing me. Of course, I normally don't drive like that. Anyway, I'm so happy I get to drive my otherwise perfect car for another year all because of this product.

It works great for a while. My engine light went off about two weeks later it came back on. Whatever's in this product works for a while but obviously you have to keep using it but so far it has kept me from having my catalytic converter changed.

Works as advertised
Reviewed on www.walmart.com·Gus
Did exactly what I expected. After the treatment, fuel economy increased slightly and the engine ran better. \nThe instructions say to get down to 1/4 tank (or 4 gallons) of gas, add a bottle, run the engine for 15 minutes and then refill the tank. To be clear, it's OK to run the engine longer than 15 minutes if you want to. I was shooting for maximum benefit and I know how far my truck will go after the gas light comes on. I added the bottle and then drove for nearly 2 hours (55 miles) before refilling the tank.

Reviewed on www.walmart.com·ITGuy
2012 Accord V6 with 165K miles. Started getting the P0430 code (catalytic converter efficiency error). I didn't expect much but thought I would give this a try before replacing the converter. Ran from 1/4 tank to near empty. Immediately started noticing more HP. Really pressed the gas pedal down whenever safe at stop lights/signs to help blow it out. To my amazement, ~50 miles, MIL P0430 dissapeared and check engine light went off. This stuff worked for me and I am very happy with the results!

Reviewed on www.walmart.com·JEAN
The dreaded "code light" came on in my car and the code was "low efficiency catalytic converter" ... great. So I tried to find out if I really need to get a new one, extremely expensive, or could I do something else. So, everyone I asked recommended Cataclean. I got it from Walmart and put it in the car, and this is supposed to clean it rather than replace it and that will be good for me. Could happen again, but hoping it won't. Happy with the product.

I don't know if I would recommend this product yet, because it did not seem to do the job the first %26 only time that I have used it, but I understand you have to repeat its use to actually see it work. It was recommended to me to use it to clean out my catalytic converter so my check engine light would go off and it would stop coming on and telling the computer check that it needed to be fixed or replaced. So I plan to use it again as recommended by the manufacturer and then I will give it another review.
