"My old truck went for its MOT last week and my fear of it failing with the new emissions went with it. I added Cataclean a week before the MOT.
Well I needn't have worried. It not only passed but the emissions were far lower than last year when I looked back at last year's certificate. 
Last year I hadn't used Cataclean yet but using it for the last 12 months as directed it has made my L200 so much better on emissions than even my mechanic expected. So another glowing review for a product that clearly works not only on fuel consumption but on the emissions as you say. Never had any doubt 😁

"I normally put in Shell High Octane diesel into my Peugeot Expert before a council taxi test, followed by Cataclean. I did not put Shell in this time, but no matter, a bottle of Cataclean Diesel, a run down the road for 10 minutes and got a nice cloud of 'black smoke', test emissions results 'very good - nearly insignificant', from a tough tester. Cataclean - bloody marvellous!

"I just wanted to write in and say how impressed I am with Cataclean! My car is a Volvo S60 D5 and recently it had been feeling sluggish and although I had tried a couple of other cleaners, they didn't seem to make much of a difference. So I thought I would give Cataclean a go before I took it to the garage and I'm so pleased it did as it has made the car go as well as it used to almost immediately. I still have no idea what was wrong with it but whatever it was Cataclean fixed it.

My Saab 9 e 1.9 tid was running badly ... Lumpy and the mpg had dropped to 25.3!! Had wafts of black smoke from exhaust. 

Got some Cataclean and emptied it into my tank. Then I took the car out for a drive. I could tell it was smoother after about twenty miles. Got home and checked the mpg .. Up to 43 which it where it normally is. The power is back and it is showing me 44 mpg now, no black smoke and smooth running. I am very pleased and will order another for the three month treatment as recommended.

What an amazing product . My car failed it's MOT due to emmissions. I was told it would be cheaper to scrap the vehicle rather than get it fixed. I bought this product used it and took my car for a good run . I then went to another garage for a second opinion & it passed that mot without any problems. Would definitely recommend buying this product.

I am a courier and bought my latest van last November. I run it 6 days a week for an average of 8 hours a day and in that period I might turn it off 5 or 6 times so you can imagine how hard the engine is working. The van has been chucking out thick black smoke whenever you rev it a little to hard so I thought I'd give this product a go ( last van cost me two new converters ) I added the cataclean this morning and just left the van to idle for 20 minutes as I won't get round my routes on a quarter of a tank. Ran the van as normal all day and when I got back to the depot in the evening I put her in neutral and gave her a bit of a rev... and ... NO SIGN OF ANY BLACK SMOKE!! excellent product which I would recommend all day long.
