I was in the local motor factors shop and a guy was buying about 6 Wynn's engine Flush in little cans and he also bought some CATACLEAN for removing sludge and coke build up.
He was a mechanic and over heard me about giving the EGR another clean and he owns a Passat with 250K on it.
He suggested the CATACLEAN would clean out the turbo, CAT, EGR and manifold anything where the fuel and air was going to pass through. After he said get engine flush to get rid of any deposits left in the oil.
So questions:
Would you use any of these products?
The engine Flush said do not use with high millage cars over 75K.
I took out the EGR today and it was spotless since it was last cleaned about 20K ago?
This all came about due to MPG being a tag low of late.
I've never used engine flush or any Redex or CATACLEAN type of derivatives just regular oil changes.
Discuss!

Can't remember the brand but some stuff ECP now stocks some oil flush stuff sorted a sticky tappet out on the GFs car. Wasn't a believer til then, still don't know if I like the thought of using it or not really.

I used forte engine flush on my old Astra ecotech engine many years ago.It had had a sticking valve was quoted 1500 quid for engine rebuild best 8 quid i ever spent.Cant recommend it enough tbh..
-
Great unless it removes the crap holding your rubber seals together. ....
Never stick it in an old engine unless its your last hope
-
Engine flush or the cataclean stuff?
-
^engine flush as said it is sometimes the crap/deposits that are keeping the seals sealed and the engine flush can remove it, my old caddy tdi was sounding a bit rough even after an oil change so i ran some engine flush through it and changed the oil again less than a week later i noticed a couple of places were slightly weeping oil and i dont think it was a coincidence. it did run a hell of a lot smoother though :cool:
-
I've been on a forte flush training course. Can't fault any of their products. They all do exactly what they say on the tin.
I use oil flush every time I do oil changes without fail.
-
I was reading about Cataclean and I still can't work out how it cleans the CAT if its combusted at engine level?
Anyways I've got soot issues and low MPG, cleaning the EGR and getting some life back into the diaphragm shaft seems to have brought it back to life and got an extra 6MPG on the trip comp.
I've ordered the Cataclean and will report back if MPG and engine will be more responsive!
I'm Curious as for engine flush I might give it a miss as I've got over 70K and seals might be wearing thin?
-
I have only ever used that Redex injector cleaning stuff and it worked quite well. My sisters partner has been in the trade for 30+ years and can't recommend it enough. When I used it I just primed a new fuel filter with it neat and reved the balls off it for a minute or two. No smoke at all now, even under load! :smiley:
-
Does Redex still smoke a 1000 cigs after you stick it in :laugh:
Happy to report got another 10MPG out of her since sticking in Cataclean but I did clean out the EGR again which probably did more good than the Cataclean.
Was getting 30MPG around town now back to 39MPG, Motorway was getting 45MPG :shocked:
I always know when the car pulls harder at 3K rpm and only getting 80MPH now it sits happy at 2.5K rpm @80MPH.
-
I had a disagreement with a cataclean rep as he guaranteed that stuff would clean my cat despite me saying a dozen times I don't run one! It does sound like good stuff but so many have come on the market recently that all have similar claims so which to buy? (My factors sell cataclean so it's a bit cheaper)
-
I'm still skeptical as it in theory the stuff should atomises in the combustion chamber leaving very little to clean the cat. But I do believe its enough to clean the lambda sensor and any debris in the fueling system.
TBF MPG has gone up, I was doing the Italian tune up when it was in the tank. :evil:
470ML is not gonna hurt in the big smoke block, but I reckon sticking some V power diesel would do the same thing as they have just launched its cleaning additives. @ £12.75 and its saving me fueling up at the pump I can't complain really!
It does say for maximum performance use it at least three times a year :whistle:
-
I will give cataclean a shot next week and will get some exhaust readings before and after (I run it with a tank of v power every so many tanks and it does get driven hard every so often). It's worth a try for the money (at trade)
-
Since sticking in £20.00 after Cataclean I managed to get 134 Miles till red light came on.
So @ £1.34 per liter which worked out roughly 42.4MPG around town not bad for a two tonne brick. :lipsrsealed:

I am going to try this next week (I know this week I got 38.1mpg from my house to Humberside airport and I'm due to do the same trip Thursday next week, so will see if it gives me any different)
I hope so as under 40mpg from a 2.0 8v slug is disappointing!! :sad:

Redex was the only thing ECP had in stock today. Filled the fuel filter on a 3.0 Iveco Daily with it then the rest of the housing with diesel. Instantly took it for a massive hammering and watched all the soot come out.
Result: Injector stopped tapping and it's got some balls back in the thing plus the smoke it was producing all the time is clearing up now.
This is a 2012 van.

Whole aim of a engine flush is to remove deposits that build up in the engine. Now, get me if im wrong, but you dont really want deposits floating around your engine and blocking important galleries. If people have looked at insides of engines, you will find that 99% of them are usually pretty clean inside oil wise.
EGR cleaners are never going to work, For a start whether they go in the fuel or the oil...neither of this has anything to do with the EGR valve. Best way to clean that is to remove it and clean it out manually with some petrol and a brush to break down the carbon deposits.
Same with the fuel stuff, you dont really want to be breaking down impurities (if any of them actually do it) and then them travelling along your fuel pipes and blocking an injector.
next time you have a terrorclean or a sales rep for forte, ask them what project they would recommend for cleaning a TSFI engine deposits on the valves etc. If any of them give a answer they are wrong as its impossible to clean any of the intake system on a TSFI due to the direct fuel injection into combustion chambers.
IMHO, all these 'cleaner' products are a big con.

I agree with the oil flush even though VW do this and BMW in all services!
I've heard that if you do use it then you need to do an oil change at least twice afterwards to get the oil thinners out of the block. I've heard horror stories with engine flush thinning out the oil too much, or leaving inside the engine for too long stripping and grinding metal. Even oil seals going afterwards causing sump/gasket leaks.
As for Cataclean it was so little that went into the fuel tank, whether it helps or not is no different than the additives they stick into the fuel like shell V power stuff.
I'll wait until BoneBrady does a more scientific result of checking emissions before and after as I've already stated I've cleaned out the EGR valve already before sticking the Cataclean in.
:whistle:
Chuff no whistles you own a big old smoke machine, so fess up you must have used a product at some point? :tongue:

Seafoam?!

Nope. Never needed to :lipsrsealed: BUT dismissing all this type of product is just nonsense.
I have seen first hand that " sometimes " they can and have saved people a fortune. :wink:
But hey, what would I know, I am a mere After Sales Assistant :evil:

Here's some results from cataclean added to my 110'000 miler Mk3 2.0 8v (running without cat!)
1st fast idle test
CO level = 0.51 % vol HC level = 31 PPM Lambda = 1.109
2nd fast idle test
CO level = 0.50 %vol HC level = 19 PPM Lambda = 1.109
and after
1st fast idle test
CO level = 0.39 % vol HC level = 29 PPM Lambda = 1.109
2nd fast idle test
CO level = 0.37 %vol HC level = 18 PPM Lambda = 1.109
It has reduced the CO and HC level's on my de-catted car to just outside m.o.t limit! I will record fuel economy this weekend and compare to last weekend's (the car does the same journey every Friday and Saturday). It certainly reduces emissions and if it improves fuel economy, well it will pay for itself and is a bargain buy.
I will update the thread with mpg results and a further emission result early next week :smiley:

Which is how they should be viewed.

Good results BB I think after a few doses I'm changing the fuel filter and oil see if that will help with a few issues!
I think I have a boost leak somewhere aswell as I can see oil from the EGR pipe so hopefully the MPG will be better as it gets serviced. I wouldn't have bothered 10 years ago, but fuel prices is like being a junkie at the pumps and long term hope it saves me some money! :smiley:
