    Rated 5 out of 5 by This stuff really works. I was recommended cataclean by a friend in work as my car had been off the road for over a week due to egr problems. After a new valve fitted I bought cataclean for my car and what a difference the engine performs as it should felt free and lots of power the mpg increases to. Anyone who's had bad emmisons or egr carbon problems I recommend cataclean and take the car on 15 min drive you won't be disappointed. 03 October 2016
    Rated 5 out of 5 by Sceptical of all the products having used other products on the market in a variety of vehicles I was sceptical about how this would make any difference to my Aged Alfa Romeo, having barely scraped through its MOT last year on emissions I was left contemplating and expensive engine clean or at least a try of something else. I read countless reviews on these sorts of products and out of everything on the market this had a higher percentage of positive reviews over everything else. So I bought a bottle did what it said on the instructions, and this seems to be the key to this actually working, and within about 15 minutes I started to notice a differenc in the running of my car, after 30 minutes the car was idling a lot more smoothly, I have since filled the car up and so far covered 250 miles and still have a quarter of a tank of fuel left, I shall be repeating this again for the next couple of months and seeing if this was just a one off or if in fact this stuff does work. 17 June 2016
    Rated 4 out of 5 by worth a try ! After being told that my 2004 Jaguar x type would fail the MOT on emissions by a so called Jag expert garage I thought I would try a bottle of this and poured it in when I had a quarter of a tank of petrol as recommended and then drove for 20 minutes mixed driving (urban & motorway speeds). The first thing I noticed was the car seemed to run better with more power. After another bottle and the same test run I had another garage do an emissions test even though the car wasn't due for an MOT, guess what ?? it flew through with no problems and the test results showed it was running well within the limits..........so...............did it work or was the first garage out to make some money out of me ?? As far as I am concerned there must be something in it and the reviews I read were mostly positive so yes, it's worth a try £15 or so or a new "cat" at £100's what is there not to like !! 05 May 2016
    Rated 5 out of 5 by Worked for me I used before an MOT and the car sailed through the test, It may be a placebo but I felt the car was more responsive after as well 21 April 2016
    Rated 5 out of 5 by Never used anything like this before I've used the other products on the market before to get emissions down on cars for mot but never really found anything that has worked must of spent hundreds since I started driving. Car failed it's MOT on the emissions and that car had already had the filters changed oil and spark plugs but it still failed. Didn't know what to do my car is 12 years old now and couldn't afford a new cat so I spent £16 on cataclean but it into the fuel and drove my car for about half hour couldn't believe the difference in the performance of the car I didn't know the car engine had lost so much power. Next day MOT retest day so I drove the car for another half hour before MOT and dropped car off for retest. The car passed with flying colors so £16 and about a hours driving saved my from having to buy a new cat at £650 or another car. This is the best engine cleaner I have ever used it is amazing 03 April 2016
    Rated 4 out of 5 by Helped on MOT Just failed my MOT on emissions. Was recommended Caataclean. Got through on the re test. Good value 15 March 2016
    Rated 3 out of 5 by Cataclean, not clean enough Having followed the instructions on the bottle to the letter and had the car retested for the MOT and although the emissions were reduced, it still failed the test, which resulted in the car requiring a new catalytic converter. At almost £16 per bottle it is a small price to pay for getting the car through the MOT, but if it fails, it is frustrating to think the money would have been better spent being put towards the new cat. So don't expect this product to cure your emission problems. It's all a bit of a gamble. 11 January 2016
    Rated 5 out of 5 by Cataclean is great! My engine was performing badly (not pulling up hills and similar to fuel starvation at 3000 revs). Added Cataclean as specified and had an immediate improvement. Saved me £900 on quote for a replacement cat! I also think that it's improved my fuel consumption. 25 November 2015
