Cataclean is a patented EPA approved complete engine, fuel and exhaust system cleaner that reduces carbon build-up and also cleans your vehicle's oxygen sensors, fuel injectors and cylinder heads. Cataclean does not alter fuel composition and is safe for gasoline, diesel and hybrid engines. Testing at an independent emissions testing facility showed using Cataclean can lower your total hydrocarbon emissions (Performance results are dependent on driver habits and vehicle condition.) Use Cataclean to fix drivability issues such as power reduction, hesitation and hard starts, as a pre-treatment before an emissions test or to extend the life of your vehicle. A well-running engine helps to restore and maintain catalytic converter efficiency. Use four times a year to help maintain proper engine operation.
CATACLEAN® PETROL
THE ultimate in fuel additives, Cataclean® cleans, restores and protects the entire engine, fuel and exhaust system.
Simply pour into your fuel tank every 3 months (or every 3000 miles) and Cataclean® will remove harmful carbon and resin deposits. With long term use Cataclean® can protect against build-up and clogging which can prevent failure of your engine and exhaust system parts.
Cataclean® can assist with your MOT inspection by bringing down emissions by up to 60% - the difference between a pass and a fail.
Cataclean® increases MPG (miles per gallon) saving you money on your fuel. Plus by using Cataclean®, there is no need to use premium fuel, more savings to you.
Cataclean® will improve BHP, torque and throttle response, improving overall vehicle performance
Do Catalytic Converter Cleaning Sprays Work?
Additive and cleaning products such as Cataclean claim to clean a vehicle's catalytic converter, oxygen sensors, fuel injectors, and cylinder heads. Customer reviews tout different results, but we’ve yet to see substantial evidence that these sprays are anything more than marketing-heavy stop-gaps at best, snake-oil at worst.
Yes, Cataclean is EPA approved, but it’s better to find the real problems and fix them the right way. Expedition Money LLC

I did some online research and Google told me that this could be the issue. Went to Auto Zone and bought some Cataclean. Got my tank down to a quarter, add the Cataclean, drove for about 10-15 minutes, filled up my tank, drove around some more....and the check engine light went off and my car is running smoothly again.

I drove it for about 3 weeks with light on and decided to unhook my battery, reset engine light and I drove 80 miles to complete a drive cycle and the engine light didn't come back on. I pulled into inspection station and passed.

What might’ve happened is that the catalytic converter itself is fine, but one of the sensors was slightly dirty from either burning a small amount of oil over time that isn’t noticeable, but a little solvent is probably all it needed to get back to it’s happy place.

Its works well. Here in the UK if your car is over 3 years old it has to go through a rather tough government test every year at a cost of around £45, I mean these test are really tough. One of the criteria is exhaust emissions. My wife drives a smart for 2 convertible but she does very little mileage its only covered 48,000 miles but as its not a daily it failed the emissions test last year, the guy at the desk recommended I went to the lock car shop and got a bottle of cataclean and drove the car "hard" for 20 minutes or so and then return. I did this and WOW the emissions had dropped to within the acceptable level, a pass WHOOO HOOO. Yesterday this years test so before I went I got catacleam, did the drive and it flew through the test so for me its a winner winner chicken dinner.

[@otpyrcralphpierre1742]

One thing that most people are not really aware of...the Cat clogs up when your engine uses oil. Most people on here regularly change their oil, but most do NOT change their PCV valve. If this valve fails, your engine may well be sucking up oil into the intake. If you have to clean your Cat, change your PCV valve. It's Cheap, and it just might prevent it from doing it again.

[@Powerstroke98]

Having a turbo six in my F150, I have a 'catch-can' that catches anything a PCV would capture, but your right, many forget to change this valve! Keeping unburned fuel or oil, certainly is not good for the CAT, so keep your engine running well, and you'll have your converter last much longer! I hear that using a higher octane fuel, also helps to keep the car/vehicle from running too rich.

Also worth cleaning your maf sensor with a maf sensor cleaner if one of the metal legs are dirty and holding onto the carbon then spray it in the holes and on the sensor let it dry and your emissions will greatly improve!

[@NetCreativeMinds]

I used this because my check engine light came on in my 2015 tundra. It was throwing code p0430. I will say that it definitely made my truck run noticeably better, however after further inspection I noticed that after my oil change that I got at a Toyota dealer, they had not reinserted the dipstick all the way in the engine bay which I believe is what was causing the code to appear. Just a reminder there could be other causes for this code appearing other than just a dirty / bad catalytic converter.

[@danc2014]

Dip stick loose will allow air into the crank and thus the valve cover. The PVC system need a closed system else this extra air will enter the intake and throw off the fuel mix. You now have an uncontrolled combustion and the O2 sensor and computer will not align and see any proper adjustment thus a code is created. Hope it was a simple fix that you saw, just like a loose gas cap code.

I put in 1.25 gallons of high test. Ran all of that through with the CataClean an an the error code was still there. I drove highway miles and did 50 miles on tow/haul which pushes my rpms from 2300 to 3000. Last 4 miles was city driving. Error code still there. Keep in mind I averaged75mph highway to heat things up. Also when I bout the truck at 189K the oil was black and it was really bad. I’ve been changing my oil at 1500-2000 miles since I’ve owned and the oil is almost clean now. So after I ran the CataClean I put some Lucas and 3 gallons of hi test in. 1 1/2 gallons down and I’ve still got an error code. After I run the next gallon I’m gonna fuel for work and reset the computer and see how long I go without the code if it comes back. I just took care of an EVAC leak a 1.5 months ago. Uggh. I’ll update.

Lacquer thinner is actually a secret in the automotive industry that actually works very well. Even highly qualified mechanics have known to use lacquer thinner as a way to clean your catalytic converters. Also if your engine is running efficiently and running properly the catalytic converters should last a life of the car. If the car is running too rich or if it's using a little oil it would be a catalyst to the converters failing. It would be funny if the cataclean was just a bottle of lacquer thinner. LOL

Hey sorry to be a little critical here, but we can all learn… that's why we're here! I agree with Paul M below. He is correct. Unfortunateley, the code you have is for the heating element/circuitry in the oxygen sensor. Cataclean would have virtually zero effect on this code. P431 is NOT set for catalytic converter inefficiency, which is a P420 or 430. Notice on your scanner- "O2 sensor warm up". If it was a 420 or 430 it would say "catalyst inefficiency below threshold -bank one (or two)" The light probably went out because th element is just starting to fail or there's a loose connector/wiring issue somewhere. If the ECU doesn't see the same problem for 1 to 3 additional drive cycles it will turn the light off. All of your theoretical knowledge is correct.... it's just the wrong code....it's an oxygen sensor code... so I don't believe this is a valid test of Cataclean. Easy mistake to make. That said, in my own experience, if you run it hard with the RPMs up for about 20 minutes, and the cat isn't too far clogged, Cataclean generally works (laquer thinner too) most of the time. I have seen the actual change on scanners with cat temperatures/ fuel trims etc. Tip: Even if you don't suspect a problem with your cat, run it at 3-4000 RPM for at least 5 minutes on your way to your emissions test, Right before you arrive at the test station is best. Test results can be night and day if you don't get those cat temperatures up. I've had multiple vehicles fail miserably where customers don't warm them up thoroughly - I mean the converters - and then doh! it will pass with flying colors 20 mins later ....just because they ran it hard before the test. Those cats need to get good and warmed up to do their job, especially if they have alot of miles on them. Hope this helps... and keep up the good work.

Is it something to worry about if my county in my state does not care about emissions? Don't need it to pass. I also got a CAT put in already last Spring. But the p0420 code is the only code that is appearing and giving me the CEL light.

[@richardhill2379]

Hey there, dealing with this right now, I had the PO420 code. What you have to check first is for vacuum leaks and if you have a lean or rich mixture with your car, if your car has poor exceleration it might be your spark plugs need changing and also your PVC valve it might be stuck open or closed, if so clean it out and do the shake test, if you hear the metal bead rattling then its good, if not replace it. Check your O2 sensors and replace both the up and down sensors, clear your code and see if that helps. If the code comes back after checking for vacuum leaks, new plugs and PVC valve, then you may need a new cat. My situation was I had an exhaust leak, my exhaust manifold cracked down the middle so I put a new one on, I changed my plugs, replaced PVC valve and replaced both my O2 sensors and cleared my code. Now it's been one day and the code has not returned, so I am playing the waiting game. If the code returns I will have the catalytic conter replaced. For my experience, Cataclean did nothing regarding this code PO420 for me, but it does clean your engine abit. I used it one bottle to a full tank and felt some improvement with my car, with that in mind, I was afraid of it doing damage if I used a bottle with 1/4 tank of gas, this stuff is very powerful, just saying. Good luck man !!@@kevinbennett4856

My mechanic has quoted me $100.00 to clean the catalytic converter. He said it works about half the time. Otherwise he say about a grand parts and labor to replace the CC short of all the O2 censors.

Is that stuff just the same as fuel cleaner ? if so it work for a few weeks as an octane booster and mask out any lean conditions. Most probably clean your injectors more than anything as it would be burnt up in the combustion process before it could reach the cat. Good for improving your emissions before a test but I doubt it will do anything for the cats long term. Your O2 sensors or the fuel trims are the reason for the codes not the cc. If the cc is blocked then that's a different story and that stuff wont unblock a cc.

EGR's lead to plugged up catalytic converters... Because the engine is re-burning exhaust fumes, just like these newer diesels with DPF and SCR systems getting plugged up from sooty exhaust being filtered thru a mesh.. except gasoline fumes are alot lighter but are moist and carbon sticks to the moisture.. especially in EGR vehicle's.
