    Rated 3 out of 5 by from Dont know it it works or not As the title says I don't know if it works as I ended up replacing the cat on my pug as post cat sensor was following precat sensor, however at this price will get from euro carparts for half the price.

    Rated 5 out of 5 by from Does exactly what it says Bought to fix an emissions fail (only failed by 0.06). Got the car to a quarter of a tank of petrol, poured it in, went for a 20 minute drive down the motorway in 4th and low and behold. Emissions was 0.11 instead of 0.36. Make sure you give your car a good blast down the motorway before taking it to the test centre. Also worth using a higher grade of petrol ( 98 ) when mixing in a quarter of a tank so that it cleans everything out! Definitely recommend. Get it when it's discounted and use it in your system a couple of times a year, old cars will handle better and you will notice a difference.

    Rated 5 out of 5 by from Does the job Have an astra convertible that sadly failed emissions last week quite badly, tried cataclean in a quarter of a tank and took the car for a blast down country lanes using only 2nd gear in high revs to get everything properly hot, took the car back the next day and im pleased and relieved to say she passed, not a miracle cure but definitely worth a try

    Rated 4 out of 5 by from good product I used this to help get my car through the emissions test for my last MOT. After using it I also took the car for a long run on the motorway because using it just for short trips around town, it failed the year before. My car is seventeen years old but in good shape.

    Rated 5 out of 5 by from Highly recommend if self servicing for emissions. Renault scenic Diesel CDI Note product says petrol on the label but their website confirms it is also diesel compatible, or you can buy their diesel version. Emissions were 3.74 , MOT requires 3.00 Changed oil and oil filter Cleaned EGR valve Put in cataclean as instructions Checked air and fuel filters were clean. Ran engine at 3000 rpm for a few minutes Took a 15 minute normal drive Result emissions tested 0.65 MOT pass. Conclusion: highly recommend this product.

    Rated 5 out of 5 by from It's not snake oil Step daughters fiat panda 1.1 2004 failed its mot on emissions. And the garage recommended her to scrap it. As her mum also has a panda I said we would buy it for parts. Anyway on picking it up I thought it was far too good to scrap. So second hard parts were sourced where needed but at £200 for a cat. It would make the car boarder line for an economical repair. So cataclean was bought. One oil plug and filter change later, the air filter was reasonably clean by the way, a bottle of cataclean stuffed in the tank and the car given a good hard drive. (Italian tuning) Performance appeared to be better after about 5miles. Better acceleration and top speed. Noticeable even though it's only a 1.1! Anyway the mot Result was a pass. I think at least partly due to the Cataclean. So it gets the big thumbs up from me

    Rated 5 out of 5 by from amazing My car failed the emissions test with 0.273 CO. After that I stopped using the car and it has been laid up for 18 months. I recently decided to try again. I got some Cataclean, filled up to 1/4 tank with Shell V-power fuel and added the Cataclean. I made a 10 mile run to a pre-booked MOT test keeping the revs at 3000 to 4000rpm. It passed the emissions test with 0.11 CO.
