Good product that worked well in BMW.

My 90,000 mile petrol 3ltr car had passed its MOT, but advised the emissions were getting close to the limit. The car is one I only use lightly about 2-3000 miles a year & sits around in winter with very little use. It is however serviced every year regardless of the low mileage. I read about cataclean & thought it wouldn't harm to try it especially in view of the cost. Following the instructions & YouTube video I gave it a try. The results were remarkable. 300 miles after the treatment the tickover is smooth as silk, the fuel economy improved & a quick test at a local friendly garage showed a remarkable improvement with the emissions. I can only state it appears to have worked for me. The only consideration I have is the 2nd test was done after the car had been driven for 300+ miles so may have cleaned itself out anyway. The car is maintained regardless of cost so maybe I'll just add this treatment before it's next MOT next year & see how it performs. Overall if you have an emissions issue its worth a try, just don't expect a miracle if your vehicle requires maintenance.

My daily hack is a 2000 Volvo V70 T5 which I have owned for 17 years and which now has just slipped past 260k miles. The car has always been well maintained and has been a faithful servant for 20k per year commuting and dog-lugging for a number of years, largely without any real hitches. Over the last several weeks, however, the car has been stuttering markedly between 2000 and 3000 rpm and has been throwing up a CEL and OBD2 codes, indicating both rich and lean running, at random, every 100 miles or so. After cleaning the MAF sensor, checking for vacuum leaks and replacing the boost control valve, all of which are a likely culprit for the issues I've been experiencing, the problem persisted. Although the lambda sensor was replaced relatively recently (c. 30k miles ago) and the spark plugs are only around 12k miles old, I thought about replacing both items as a prelude to the dreaded, last resort, injector replacement and/or new ETM module. As a shot to nothing, I first threw in a bottle of a quality PEA-rich injector cleaner - which made no real difference - followed by a bottle of Cataclean into the last 15 litres of fuel in the tank. After a 100 mile commute, on a freshly reset CEL light, the problem appeared to be cured. The car pulled like it should, the hesitancy/pinking had gone, and after what now amounts to 500 miles of driving I haven't seen a recurrence of the CEL light or the pinking/stuttering on boost. It may only be a tub of acetone and xylene, but it evidently works very well for certain niggly issues relating to potentially gummed up components in the emissions and exhaust system. Worth a try if you've got an older car with a troubling, intractable, and potentially expensive issue.

Bought product with slight trepidation......but....crikey....filled tank with solution, then quick run round block. Car sat for a few days until had to do longer journey allowing engine to heat up - what a difference. Engine much more responsive and smoother. Will see if consumption improves, but engine response is amazing.

I was recommended this by a friend who swore by it to get me through my emissions test for mot. The car it went in was a 1994 Toyota supra twin turbo. Last year's mot was just about a pass for emissions(very close to the limit) and where parts aren't readily available for my car (if parts are available they come with the added jdm supra tax!). I thought I'd give this a go. I had a little too much fuel in my tank but was a bit scared to use this with the less stated fuel to cataclean mix ratio considering the car is old and has a £6000 engine, which I was scared to cause damage to. Mixed it into a 3rd of a tank of superunleaded (+25 litres approx). Let the car idle for 10 minutes to get up to operating temperature. Then cruised at 50 to 70mph for about half hour. Feeling confident the mixture was safe for the engine I started driving in lower gears doing hard pulls in the car. I drove this pretty much close to empty didn't take long considering the type of engine it is. Then filled up with super unleaded. 1 week later it had its Mot and passed with flying colours! Well within the emission limits and actually surprisingly almost too low on the Co figures. I now swear by this product and will be using it throughout the year to keep the fuel and emission system as clean as possible. Car drives alot smoother, and pulls a bit quicker too. I did a 0-60 before and after to make a comparison and it was 0.45 seconds quicker after the cataclean.

Postage was OK. Had a error for 02 sensor one up. Read reviews to say this product gets rid of it. Well I followed the instructions. 1 day after putting it in the error went. Great stuff. Getting low on fuel so filled up as normal. Driving as normal. Half a tank later the error is back. Same one as before the 02 sensor. Didn't work. Looks like I am going to have to pay out and get a new sensor put in. Also did not notice a increase in mpg as it says. Can also get it cheaper in other places.

I decided to use this because I was having problems with my engine management light coming on. I took my vehicle to the main dealer and they put it on the diagnostic computer, which showed the emissions were not right. They suggested it was probably a bad batch of fuel and told me it was fine to drive, once I refuelled I should have no more problems. I then paid the £35 for the diagnostic and went away happy the problem was not going to cost me a fortune. As you can probably tell already, I know nothing about cars. Several weeks later, the engine management light came on again, so it was another trip to the garage. It cost me another £35 but this time they told me I needed a new catalytic convertor at a cost of £600. I was shocked. My car is nine years old, but I'd had it since new so I know it was well looked after (rarely used & serviced every year). My friend told me about this and I found it easily on Amazon. I ordered two bottles and straight after use immediately noticed it was running far more smoothly. The downside was the dreaded engine management light was still on. My car is quite large and my friend suggested I order another bottle or two. Well another two bottles later (four in all) my car is running really smoothly and the dreaded light went off. I have waited several weeks til posting this review and the light is still off, and the car is running like new. I thoroughly recommend this product.

I think the Cataclean did help. The fuel economy has improved and so far so good no error message has re-appeared appeared.

Bon produit

Muy buen producto cumple con lo que se promete en menos de 24 horas se quito el error del carro por culpa del catalizador se borro solo 100% recomendado "APROBADO POR CHAYANNE"

This is my story. My Honda Odyssey EX-L 2005 (85K miles, first owner, bought new, all regular maintenance) all of sudden had a CEL light on 11/22/2016. It threw a code of P0420 pointing at catalyst system efficiency below threshold (bank 1). Based on my research, there are too many things that can cause this code. However, if it comes to the catalytic convertor or oxygen sensor replacement, the expense could be too high. So, I decided to take care of it myself before I go to Honda dealer or other mechanics. I first changed the engine oil at Walmart, just regular Quake 5w20 oil. Besides, I asked the technician at Walmart to add a bottle of Lucas (heavy duty Oil stabilizer, white bottle) as well because the engine seems to burn a bit oil over time. I also filled the gas tank up (regular 87 gas) and added a bottle of Heet (red bottle, Heet Fuel Line Antifreeze, Water Remover and Fuel Injector Cleaner) into the gas tank to remove water and hopefully to clean the fuel injector. Then I cleared the code myself and started driving the vehicle locally. After driving about 135 miles, the engine light was on again and had the same single P0420 code. At the time, the Cataclean I ordered from Amazon arrived so I want to give it a shot. At this weekend (12/03/2016), I already drove the car for about 190 miles since I filled the gas full. I poured the whole Cataclean into the gas tank, which had a bit less than a quarter tank of gas. Then I drove on to highway. As some reviewers suggested, when there were no cars close to me, I stepped on the gas pedal hard (almost 'floored' it) to get RPM to 5K. When the RPM reached 5k, the speed of the car was about 85 miles on highway and then RPM immediately fell back below 4k and 3k itself. I released the gas pedal to slower the car. (If you do that as well, do be careful. Nobody wants to get a speed ticket on high way, right?). I did the same cycle for about 5 times on highway: slowing down to about 60 miles/hr -- flooring gas pedal to reach 5k RPM (speed over 80 mile/hr) -- releasing gas pedal to let the car slow down. After driving about 30 miles, I stopped in front of a mall to shop a while. About 15 minutes later I came back to the car and started it. You know what, the engine light was off, on its own! I drove another 40 plus miles after that and stopped at a gas station to add some fuel. I just added 6 gallons of regular 87 gas. As I do not plan to add premium gas in the future, I did not want to do it now as some reviewers suggested. With 6 gallons of fuel, I drove more than 120 miles before I filled the gas tank again. That 6 gallons of gas gave me about 21-22 miles/gallon gas mileage, which was about right for Honda Odyssey. The engine light is still off (after driving 170 miles). I felt the car was getting more power after adding the cataclean. The acceleration was smooth and more powerful. I did not observe any black smoke (or any kind of smoke) from the tailpipe when I floored the gas pedal. The car did not have any driving issue or noise or anything. I did not expect it worked so well when I did not see any smoke or anything coming out of the tailpipe. But obviously it helped clean the catalytic convertors or oxygen sensors or whatever that threw the P0420 code. I am not sure how long the code will be off and I will post a follow-up comment in the future. Again, the car has been maintained regularly for oil change, transmission flush, and I added sea foam to gas, oil gasket, and even brake air intake lines once every other year. However, the car was driven mostly local in the past 4-5 years. I can tell you, its RPM never reached 5K in the past 5 years. What causes the P0420 code? I do not know. But obviously the Cataclean did help at this time. Spending $16-20 on the Cataclean before you touch the expensive oxygen sensors or catalytic convertors could be a good investment. I plan to buy another bottle in case the code comes back again. Good luck to you DIY maintenance.
