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.

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.

Didn't work

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

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

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

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.

Engine light goes off

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

Bon produit
