CAT-A-CLEAN Anyone Used It?



  Lionel Richie
for what? If the CAT is knackered, its knackered for a reason (fuel/spark)

no need to "clean" the CAT, it cleans itself at 7000+rpm and 1000degC ;)
 
I would have said its alot of balls but I've seen cars with cat faults and this stuff once run through the car and u turn the light out the lights never coming on again

The thing is my 54 plate has 20k miles on it. Its never driven hard and only does 4-5 miles at a time. From time to time the exhaust monitor warning light comes on. When I plug in the OBD reader it won't give me a code. I'm thinking £12 won't hurt to try and clean the full exhaust system.

Stuck a bottle of this in the car and I can honestly say I can feel a difference. Acceleration is a lot smoother. My car as said before has only been used for short journeys all it's life. I understand it's not a magic solution that can fix cats but if it can clean lambda sensors and not throw lights up every now and then it's £12 well spent. I understand there are sceptics but it does what it says on the bottle.
 
LOL at "Rather look after my engine"

So instead of giving it a decent blast when warm to clear it out, which is actually beneficial to the engine, you'd rather pour some random chemicals into the fuel system. Whilst ignoring the advice of specialists and other enthusiasts.

Congratulations, you're an idiot.

Why the need? Were you bullied at school?

I will take heed to 'specialists' advice if they explain how and why. I will not listen to sanctimonious keyboard warriors.

When your pootling around at less than 3k rpm all the s**t that goes out the exhaust gets stuck in the cat, blocking it up.

get the cat nice and warm, send that exhaust gas flying out the exhaust taking all the blocked up s**t with it thus sorting your issues.

thats it in basics. Driving around "looking after your engine" as you call it isn't actually looking after your engine and it just blocking itself up. These engines have a full rev range to play with, so use it!

So would an engine that has been red lined all its life last longer than an engine that has been revved cautiously? Also if the car has been de catted does your theory still stand.

Cars are designed to be run at certain temperatures and they are designed to have the full rev range used at least once in a whilst, pottering around in them whilst cold just causes carbon build up and blocks and chokes them, a decent run with your foot down and a good few mile at 70 in 3rd should see you clear some out. Cat cleaner does do some good but its not recommended as the engines were never designed to have carbon dissolving chemicals run through them. If you gave it a good run with your foot down you wouldnt just see smoother power delivery and better acceleration but increased fuel economy too.

Also i have worked on plenty of 172 and 182 models, the ones that are pottering around in them dont drive half as good as the ones that have their foot down and theyre getting same MPG. Also from from my experience these engines are pretty much bullet proof aslong as you keep up the service regime.

Not necessarily, poor maintenance usually kills an engine. I believe the only thing these engines really don't like is sitting at very high rpm for very long periods of time and they end up dropping exhaust valves. Otherwise the weekly blast making use of all it can give you is good for the engine.

As for decats obviously not as there's no cat to clog up but it's not just the cat that gets clogged up there are plenty of other areas of your engine that will benefit from a good blast every week/month.

Aoart from a speeding fine there's not much damage you can do by revving the nuts off your car, they are built to do that with safety tolerances in mind
 
To add to whats been said above..

Doing 4-5 miles a day, means that the engine will never get up to temperature, this in turn causes the oil to condensate, and break down a lot easier. The engine that never warms up will also still be on the cold start enrichment map, making it more susceptible to things like bore wash, which won't be helped by an oil that is breaking down.

Giving a car a good thrashing gives it a good chance to clear the blocked up ports that'll be coked up, the cat would get up to the temperature it's designed to operate at, the exhaust that will be filled with water will be able to evaporate.

Are you running it on super? Or just regular unleaded?

A few years ago I picked up a Williams 3, had a 64 year old owner for the last 10 years. When I first got it, it would not do anymore than 110mph. Just wouldn't pull atall. 3 weeks of hard driving and it would then ping off the limiter in 5th.
