## Overview

Cataclean Fuel & Exhaust System Cleaner is a patented, EPA-approved formula designed to reduce carbon deposits, clean catalytic converters, DPF filters, oxygen sensors, and fuel injectors. Safe for gasoline, diesel, and hybrid engines, it cuts hydrocarbon emissions by up to 50%, improves fuel economy, clears check engine lights, and helps vehicles pass emissions tests across all 50 states with simple, tool-free application.

## Description

Cataclean is a patented EPA-approved complete engine, fuel, and exhaust system cleaner that reduces carbon build-up and also cleans your vehicle's oxygen sensors, fuel injectors, and cylinder heads. Cataclean does not alter fuel composition and is safe for gasoline, diesel, and hybrid engines. Testing at an independent emissions testing facility showed using Cataclean can lower your total hydrocarbon emissions (Performance results are dependent on driver habits and vehicle condition.) Use Cataclean to fix drivability issues such as power reduction, hesitation, and hard starts, as a pre-treatment before an emissions test or to extend the life of your vehicle. Use four times a year to help maintain proper engine operation and catalytic converter efficiency. One application may not clean an already unhealthy catalytic converter, but the recommended four times per year usage can restore a dirty catalytic converter, maintain a healthy catalytic converter and support a well-running engine. Features: Easy to use - simply pop, pour and go every 3 months Original long nose bottle is capless gas tank compatible Does not alter fuel composition and is safe for gasoline, diesel and Hybrid engines Restores Catalytic Converter, Oxygen Sensors, Fuel Injectors and cylinder heads Pass smog and emissions tests with confidence Cleans and maintains Deisel Particulate Filters (DPF) Reduces Hydrocarbon Emissions on Gas Motors by up to 50% Reduces carbon build-up Improves Fuel Efficiency and MPG Legal in all 50 states EPA Approved Patented Formula e85/Flex Fuel safe New COEX-HDPE bottle constructed for increased strength with no evaporation

Review: Great & Reliable product! - 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.
Review: Works well! - 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.

## Questions & Answers

**Q: What if you can't go on highway my car won't go past 30mph?**
A: I don't believe that it will help if your car will not go above 30. Sounds like something more serious with your vehicle.

**Q: How many miles will this take to unclog a 2005 sentra 1.8l cat, that revs only to 2700 rpm, with no error codes?**
A: It sounds to me as if your cat is beyond repair. If you’ve already used a bottle it should fix it pretty quickly. If your car runs no better, you need a new converter. That’s what happened to me, I had to buy a new converter.

**Q: Once you add this product to the gas tank what is the rest of the process?**
A: add the product to the gas tank when it close to empty - for me that was about 2-3 gallons remaining - then really ran the car hard (like I stole it) - - filled the tank with high test  and some injector cleaner- and again ran the car hard  - check engine light stayed off for a good 6-8 hundred miles - more than long enough to pass NC emissions test - the light did eventually come back on - but then realized it was the fuel my wife purchased - - as I had her fill up with a different brand and light turned off

**Q: One person posted that they used a combination of "cataclean and solder it" in the gas tank? what is solder it - can anyone post a link?**
A: Never heard of that but you shouldn't have to mix anything with our Cataclean

### ⭐⭐⭐⭐⭐ Engine Light issue in Volkswagen jetta 2013 model
*by A***R on 29 August 2024*

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.
