About Cataclean

3d diagramPrestolite Cataclean is a fuel and exhaust system cleaner that reduces carbon build-up and cleans your vehicle's catalytic converter, 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 by up to 50%! (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.

Using Cataclean may help to avoid the replacement of costly oxygen sensors or your vehicle's catalytic converter. If you have to replace your catalytic converter, use Cataclean with the installation to extend its life.

Cataclean is easy to use – simply pour in your fuel tank. Cataclean complies with VOC (including in California) and OTC regulations, as well as federal low sulphur content requirements for use in diesel motor vehicles and non-road engines.

For optimum performance and protection, use Cataclean four times per year. Ask your retailer or service technician about Cataclean today!

Independent Testing

truck testTesting was performed at an independent emissions testing facility that is EPA and Air Resources Board certified. The test uses a calibrated emissions bench that is verified daily, monthly and annually with gases that are accurate to 1% of their stated concentration, which is better than the EPA requirement of 2%.

Cataclean Test Results Show:

  • Up to a 50% reduction in total hydrocarbon emissions in vehicles with high THC emissions. (>10 ppm THC at idle)
  • Up to a 20% reduction in total hydrocarbon emissions in vehicles with lower THC emissions. (<10 ppm THC at idle)

  • "This represents a genuine opportunity to garages in terms of gaining good will with customers by saving money on parts." - Commercial Vehicle Workshop Magazine
  • "I know what you mean about miracle cures that come in a bottle, but we've had a product in from Cataclean that does work. It's designed to clean up valves, injectors, Lambda sensors (oxygen sensors) and cats. We've done our own test on a car that failed the MoT emissions… and after adding a bottle and taking the car for a short drive the figures came down to 0.15% CO and 21 PPM hydrocarbons. If you want more info have a look on catacleanus.com." - Performance Car Magazine
