## Overview

Cataclean is a patented, EPA-approved 16 oz. liquid fuel and exhaust system cleaner designed to reduce carbon build-up and restore key engine components. Compatible with gasoline, diesel, and hybrid engines, it improves fuel efficiency, lowers emissions by up to 50%, and helps pass smog tests. Easy to use every three months, Cataclean extends catalytic converter life and enhances overall engine performance.

## 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: Cataclean Did More Than I Expected - I own a 2006 Nissan Armada V8 with over 180K miles on it. A "Service Engine Soon" message appeared on the dash... code 420 (problem with catalytic converter). I could have taken it to a repair shop and paid them a $280 diagnostic fee and then potentially another $1800 to replace the catalytic converter, but I didn't want to put that much money into a vehicle this old. I decided to give Cataclean a try. The instructions said mix one 16 oz. bottle with every four gallons of gas in your tank. I bought a six-pack to mix with 24 gallons of gas (tank holds up to 28 gals). It took about a week to run that mix through the engine, after which I refilled with gas only. I could have cleared the code to see if it came back, but I decided to see if it would go away on its own first. In less than 2 weeks time, the "Service Engine Soon" message dissappeared and hasn't come back since. During that two weeks, I monitored my miles per gallon and found that I was now getting exactly 20% better mileage! There was also a noticable improvement in responsiveness and acceleration. I wasn't really expecting all that, but the fuel injectors were obviously in need of a good cleaning... and they obviously got it! Six bottles of Cataclean wasn't exactly cheap, but it was much less than the alternative. I'm very pleased with the results and can highly recommend it.
Review: Put in gas tank when about 1/4 fuel - Good stuff

Good stuff

### ⭐⭐⭐⭐⭐ Cataclean Fuel & Exhaust System Cleaner - Pack of 6
*by D***. on 9 July 2025*

Bought this product last year because my 2016 Buick Encore engine light on fail emissions. Mechanic say might be cost more than $1k to replace catalytic converter. Use 1 bottle every 6500 miles oil change. After 3 bottles the engine light is off and car run smoother.
