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. A well-running engine helps to restore and maintain catalytic converter efficiency. Use four times a year to help maintain proper engine operation.

  • Recommended by my mechanic
My auto mechanic recommended this and using 91 instead of 87 and my car is now getting better gas mileage and just overall running much better!

  • Can confirm or deny that it works
Used for some preventative maintenance. Also when accelerating hard, I would get a sulphur smell. Haven't had that happen in a while, but I don't accelerate hard often. A bit inconvenient to use, since you are supposed to put in your gas tank when it's a quarter full. I usually fill up at half a tank. Drive for 15 miles or so and then fill up. I was not having any real issues, but used this as a preventative measure. ... show more

  • Didn't work
Didn't work for me. I have a cat converter that is borderline. Sends a CEL every now and then. This didn't resolve it. Used the 2nd bottle on another car that has similar symptoms and didn't fix that one either.

  • Check Engine Light Went Away!
I recently purchased the Cataclean 120019 Twin bottle value pack, and I couldn't be more pleased with the results. Not only does it offer great value with two bottles included, but it also quickly resolved an ongoing issue I had with my check engine light regarding my Honda's catalytic issues which according to them was just a software issue. After using Cataclean as directed, I noticed a significant improvement in my vehicle's performance, and most importantly, the check engine light, which had been a persistent nuisance, cleared up within a few days. This product's ability to clean and restore the fuel system is impressive, and it undeniably saved me from costly trips to the mechanic. I highly recommend the Cataclean Twin bottle value pack to anyone looking to improve their engine's efficiency and swiftly address check engine light issues. ... show more

  • Difference maker????
I'm not sure if this product did anything. The catalytic converter code tripped, we ran a tank of gas using this product, and a few gas fill ups later the code came up again. Maybe a second bottle is necessary to clean the converter better, is the converter bad, or is the product ineffective?

  • Worked for me
2008 jeep rubicon, code showed inefficient cat, I bought the two pack so I ran it twice in same day, I cleared code and it did not return, I did have a pending code but it still passed as it was only pending. The smog station saw the pending code on their screen and did a very thorough visual inspection but everything was stock so they had to pass me. ... show more
