Worth the cost

I've used this product twice now on cars due to take their mot. The first car had failed on emissions and passed at the second attempt after using this product. The second car also passed but the product was used as precautionary measure just in case. For the small sum incurred, I'll be using this product regardless of whether I think it's needed or not.Read full review

My car failed this time MOT on "Emissions" and I had to pay for a new "Cat" .

I cannot blame the product, but as in the title after my car failed its MOT after using the product so it didn,t have any affect with me, as my car failed on the "emisions test" and my Cat was only a couple of years old.Read full review

Very Good Product. Try it and see for yourself.

My car's MOT last time showed borderline high emission problems, but just scraped through and passed. So before this years MOT I used CataClean Liquid, and I'm very pleased to say that the emissions were very much back to normal. My car passed the test with no problems.Read full review

It is a miracle

Mr, Sceptical here had what felt like a major problem with the fuel system and it seemed necessary to have the injectors taken out and professionally cleaned or replaced after 210,000 miles. However after using cataclean the engine runs sweet and all the hesitation and misfiring has totally gone!! I was gobsmacked. Try this first before undertaking major repair work to the fuel system. You could save a lot of money.Read full review

Some you win some you loose

Had my Astra scrape through mot on emissions last year so though this worth a try before getting a new cat ,for me I'm afraid it did nothing ,eml came straight back on and after a week of resetting still no change so bought a new catalytic converter.The product may work in some cases ,it may be that my cat was too far gone 😵Read full review

Great product, worked as it said.

Worked a treat, had the engine light on which was the cat converter. Used cataclean and the next day it was off. Will use again if needed.

It works

Hi everyone. I don't know what that liquid is actually doing and what isn't but it definitely affects the engine performance positively. You will start feeling it after the tank is half empty.
