Fuel & Exhaust System Cleaner – Pass Emissions Tests – Clear Check Engine Lights – Restores Catalytic Converters, DPF Filters and Cleans Fuel Systems, 16oz (120007)

I got the code P0420 in my Dodge Charger 3.6L V6. I added this and drove the car at 125 Kmph | 75mph (5th Gear @ 2950 RPM in cruise control) for about 30 minutes (keep an eye on your engine/gear oil temp), and my check engine light is gone, and my idle has drastically improved. This isn't a permanently solution but using this in intervals, I strongly believe that this should definitely be added as a routine maintenance for your car. Extremely satisfied with the results.

I would like to say must buy product. I was going through all the review and found a good review of this product so thought I should try this for my cars since 3 years I was facing Engine Light issue which was appearing on my car dashboard. I pour this directly to my fuel tank and drove for 2 days and found that engine light got disappeared. I am totally surprised with the result. I am really happy :) as I went to so many garages and they could not find the exact issue and everytime they reset this manually with machines and its back again in few days. I suggest if you are facing same issue then you shoud try once.

First off, I assumed and got a message that the delivery would be late due to pending orders but it arrived on time. Second - I did not have any codes, and I did a lot of work on the car such as changing of spark plugs, cleaning carbon off the throttle body and the air intake manifold, cleaning of MAF sensor, and changing PCV valve. To top it all off and get the system efficient I used Cataclean and I can say the car has never been so comfortable and the engine has never been this healthy since I bought the car. I intended to clean out the fuel supply lines and catalytic with it because the car was a little high mileage. The car was above quarter of the tank, since there were no codes, I wanted it a bit more diluted rather than it being more potent and damaging something along the line. Would definitely be using it again but preferably at a 6 months interval.

Very affective product for the catalatic coverter and even feel good pickup of my car after use

So far the best product I used , can feel change in car performance and Mileage

Didn't work

It's been 2 weeks now since I used it and it is really effective

After wachting tons of videos, I ordered & used as advised but my engine light came back, I dont know whether these cataclean youtube videos are fake, I have high hopes for this product, guess I have to go to welder to take out the catalytic converter then clean it with detergent or put a new one, let's see.

I think the Cataclean did help. The fuel economy has improved and so far so good no error message has re-appeared appeared.

Muy buen producto cumple con lo que se promete en menos de 24 horas se quito el error del carro por culpa del catalizador se borro solo 100% recomendado "APROBADO POR CHAYANNE"
