    5.0 out of 5 stars Excellent product if emissions too high during MOT!!!

    A.T. · 21 February 2024

    My 11 year old Skoda (petrol) failed its MOT based on emissions, which were way too high. The garage already replaced the Lambda sensor etc and although this brought down the emissions, they were still too high to pass the MOT. Nothing else was visibly wrong, there was no engine/ catalytic warning light, no exhaust or engine noises or visible fumes, no burning smells etc. Garage said to take it to a main dealer for a more in-depth diagnostic as they couldn’t put their finger on why emissions were still so high. However, before I went down that route, I decided to get a second opinion from another local garage who suggested to try a catalytic cleaner, give it a good run out on the motorway (50 miles each way) and fill up again with 98 octane petrol (rather than the 95 octane/ E10 stuff as that apparently causes more carbon deposits and blockages in the catalytic converter and exhaust system than the previous 95 octane petrol, which can lead to higher emissions). Second garage said that if there was something wrong with the catalytic converter and the car needed a new one (£1,000 upwards), then it would definitely show up via a warning light and/ or during the diagnostics stage, so that was probably not the problem. Anyway, bought the Nitrox Catalytic Converter Cleaner Petrol via Bolo based on the good reviews from people with similar problems to mine and did as suggested by the second mechanic/ instructions as per bottle – AND IT WORKED! Car passed its MOT the second time round, with no emissions issues at all! My tank was ¾ full when I put the cleaner in, then went for a 100 mile round trip down the motorway, used up a bit more petrol commuting to work for a couple more days, booked another MOT three days after the motorway trip and it passed no problem. Extremely happy with the product and the advice provided by previous reviewers and will keep this in mind for next year’s MOT. Will also start to fill up with 98 octane petrol from now simply to prolong the life of the engine/ car – 11 years is not that old after all. As previous reviewers have said, give it a try before you fork out for expensive repairs on your exhaust system and/ or catalytic converter, especially if there are no engine or exhaust noises or fumes and the car is otherwise running well.

    Best product of this kind I have used,improved pick up and smoother tickover.Lamda didn't like it at first,didn't close quickly ,but after an hour's driving it closed as normal within 1 minute on start up.

    5.0 out of 5 stars Worked when Cataclean didn't

    g.p. · 7 July 2022

    I've always had an engine warning light on with my petrol corolla verso. I've used cataclean and had the light go out for a few miles, but not reliably. Had my mot coming up and put this in the quarter of a tank that it suggests. Didn't wait for it to clear but reset the warning light with my odb2 reader. Drover it around town for about 20-30 minutes, couldn't do motorway speeds or high revs and in that time it didn't come on. Took it for it's mot, and where we've cleared the light before but it still fails emissions, it sailed through the emissions part. TWICE!!! (it failed on failing uv joints first time!). I'd use it again. It's cheaper than cataclean, and I will add to this review after I've done more miles to see if it lasts.

    3.0 out of 5 stars Important Note: Valve Design Caused Spillage

    K. · 24 April 2024

    I recently purchased the Nitrox Catalytic Converter Diesel Cleaner, 500ml, hoping to give my car's engine a boost. While the product itself seems promising, I encountered a significant issue during use.Most cars, including mine, have a valve under the fuel tank cap that only opens when you push the nozzle into the fuel tank. Unfortunately, the design of the Nitrox Catalytic Converter Diesel Cleaner's nozzle doesn't align well with this mechanism. When attempting to use the cleaner, the spout broke as I pushed it into the fuel valve, resulting in all the contents spilling outside the tank. This not only made a mess but rendered the product completely useless for its intended purpose.I believe it's crucial for the manufacturer to address this issue by clearly mentioning the compatibility of the nozzle design with common fuel tank valves in the product details. Potential buyers should be aware of this potential problem to avoid similar frustrations.Overall, while I cannot speak to the effectiveness of the cleaner itself due to this issue, I urge the manufacturer to consider redesigning the nozzle to prevent such mishaps in the future.

    5.0 out of 5 stars Turned DPF Light off And Cleaned it.

    S. · 30 March 2025

    Worked great I had a DPF light on my dash so I order this and it come the next day I put in my fuel tank and i driven it 3k rpm for a short while and the light turned it self off and hasn’t come back on I will probably put this in my tank every other month to keep everything clean

    5.0 out of 5 stars Very good

    A. · 28 January 2025

    Very effective indeed. Car is running a lot better and you can feel the difference almost immediately. Poured it in and then ran the engine for a few minutes then took a car up a dual carriageway and the car has never felt so nippy and it’s only a Skoda lol. very happy with the product and will defo buy again. Thank you

    4.0 out of 5 stars Good value for money

    R. · 23 July 2025

    After using this I noticed a difference, the bottle is designed well and ensures no leakage. Useful if you’re trying to clear engine light to do with you cat. Also seemed to knock off my service light for a few days although now it has come back on. I was not expecting this to be a permanent fix by any means.Still a great product does what it says on the tin.

    It worked

    C. · 12 October 2024

    Sealed up a coolant leak from inside of the engine block . Made a great deal of difference and after tightening up a few bolts on the intake manifold I was good !

    It works!!!

    R.B. · 18 October 2024

    This product really works! My check engine light was on for a couple months reading that it was the catalic converter. After 2 cans of this stuff, my check engine light has been off for months and haven't come back on.

    I used 2 cans to clear the cat engine check light.

    B.S. · 9 June 2025

    I used 2 cans and it did its job. The cat engine check light is gone.

    Did not work!
