I bought this product after I had looked at reviews from several sites and gave it a try. My car mileage was 150,770 miles. I put it in has the direction said with a full tank of gas and drove from Houston to Lake Charles,La. My engine light had been on, and even driving halfway back i saw that it was still on and I had driven at least a hundred and seventy five miles, but two days later, the light went off And is still off. I noticed better pick up from when I first used it in the gas tank before the engine light went off. Now I don't have to worry about getting rid of the car or buying a new catalytic converter.

⭐⭐⭐⭐⭐ Cata Clean 8-in-1 – Genuinely Impressed!

I picked up Cata Clean 8-in-1 from Halfords today out of pure desperation. My car had gone into limp mode because of the DPF filter, and the dashboard was lighting up with warnings saying the engine was damaged and needed repair. With over 146,000 miles on the clock and relying on this car for more than 200 miles of driving every week, I was honestly worried I’d be forced into buying another vehicle.

I followed the instructions exactly, took the car out for a 30‑minute drive, and the difference was immediate. I was able to turn off the engine management light afterwards, and so far everything is running smoothly. The car feels more responsive, and I can genuinely feel more power compared to the other cleaners I’ve tried in the past.

For something I bought as a last‑ditch attempt, Cata Clean 8‑in‑1 has given me real peace of mind. It’s saved me stress, money, and the headache of thinking I needed a new car for work. If your car is showing similar symptoms, this product is absolutely worth a try.

Was just curious about this stuff but it's made a big difference to my 2.0 vivaro more oomph runs much better will change my fuel filter and put more in after a few months

Cat believe how well this has worked. I had a EGR blockage on my diesel Vauxhall insignia for years. The engine management light was always illuminated. Added a bottle of this at a 1/4 tank and ran it down over 3 days as I do 44 miles motorway driving per day.
The results now are that my engine management light is now off and the car runs and feels much better. Yesterday I drove 200 miles and I was getting 68 MPG were as before I was getting 54 MPG.
This stuff really works.

I tried cataclean diesel first time today don't know if it was me or wishful thinking but after 5 minutes it seemed quieter. Took on a 50 mile run by the end seams to be pulling a lot better. Will definitely having again in 3 months time

Used the product after C0 emissions failure on a low mileage 5 year old car, readings fast idle and natural idle of around 2.0, way above limits. Ran the car for 100 miles with cataclean and retested, dropped the Co to 0.03. combination of a good run and the cleaner worked perfectly for me. Won't fix a mechanical issue, but definitely effective at clearing the system.

Bought this for the first time told to put it in when tank was quarter full and drive it like you stole it 😂 so I did and believe it or not my milage actually went up and that has never happened in my old rust bucket I'm definitely getting this again in 3 months as recommended. Ps only went up 4 miles. But went up 👆

Don't waste your money on this. My vehicle still failed the emissions test after me putting a bottle into the fuel tank. I'll try Forte diesel cleaner instead.

I bought cataclean today cause my catalystic converter kept throwing the po420 code I bought a cat but the dealership didn’t have time to put in yet so I bought this stuff put it in and my move shot up driving the interstate and in town know granted only day one lol fingers crossed didn’t everything in the bottle down to the tea lol

I tried it on my Volvo S80 cant say its made any difference. fuel same, performance same.

I'm always worried about my mot every year as my 12 year old car spews out loads of black smoke. Follow instructions on bottle , rag car around in 3rd and 4th gear 4000 to 5000 rpm for a hour.
Took for mot passed with flying colours.
Smoke test result should be between 34 and 38.
Mine read 0.39.
Brilliant stuff !!!!!

Diesel Cataclean 8-in-1. My 2014 Nissan Qashqai threw up 3 errors all at once. Chassis error, front radar error and start/stop error. All seemingly unrelated but obviously connected in some way.
Searched the Web and one possible reason is a blocked pipe to the exhaust gas sensor! (Thanks Nissan for the helpful error messages!)

Tried unblocking the pipe with a brake cable but could only get it so far and it made no difference. I bought Cataclean from Halfords and added it to 1/4 full fuel tank. Drove for 30 mins and the chassis error disappeared withing 5 mins. Turned off the engine and restarted and all the errors were gone. It's only been 3 days but so far no sign of the persistent errors. 🤞 Fantastic stuff!!!

Bought cataclean petrol from gsf parts complete rubbish made no difference to the car - failed mot on emissions - sent off under the money back guarantee heard nothing - don’t waste your money

Bought this on advice from my garage . Put it in last week, my diesel engine was sluggish in 2/3rd gear low revs. Car not sluggish anymore , fuel consumption up about 5-10% easily. Great buy for the price.

Bought a bottle of cataclean for me fiesta it’s worked very well. It passed its mot fine. Car is running so much quiet for a diesel. Thanks

Bought this because my car was sounding really rough when idle and at top speeds . I’m suprised by how well this has worked I must of had a blocked sensor or injector this did the job I’ll definitely use it again

This stuff is over rated rubbish! I was recommend by Euro car parts on the condition that there was a money back guarantee, My car failed the MOT on admissions, So i sent of the failed MOT cert along with proof of purchase and covering letter to Cataclean in UK , i HEARD NOTHING BACK, RIP OFF , would never buy this again

I’ve got an old Jaguar S type 2007 diesel 2.7 D. I have tried everything to get my Dpf Clean all the top brands. I just happened to look on YouTube and saw this product and I can’t believe the results did exactly what it said on the bottle two hours later, Dpf light gone !!!! car is running like it is new I can’t emphasise enough how good this is I was very very sceptical , I will be using this every three months as suggested on the bottle ,Dpf has reduced from 70% fall to 42% and it is running like a Jaguar should ! and fuel consumption has gone up even though it’s not by much it still counts. Well done Cataclean !!!!!!!!
