Full Version: Terraclean Seems To Be Spreading

Recently noticed that the Terraclean system as shown in Wheeler Dealers is now being advertised on TV.

Edd China is plugging it in a big way and seems very keen on the system.

Apparently it's also available for diesels now.

Has anyone either had the treatment or might be considering it?

I'm not advertising or endorsing it but thought members here may like the look of it, testimonials seem to support the fact that it does wonders with blocked DPF's and borderline MOT emission tests.


I have found that a garage 8 miles from me does this service so will be contacting them soon to give it a go and report back as to results.

Watch this space.


Well I've taken the leap and booked my car in for the Terraclean service on Thursday, £85+ VAT.

It will take about an hour including setting up and the run through.

I will post up results/observations/etc. when the jobs done.


Looking forward to the outcome Clive!

So am I. :d
I'll probably get chucked out for taking too many photos and asking bone questions.
Maybe I need to take a dictaphone or a notebook to do a proper interview :p
Maybe if I explain it's for a review on a car forum they'll allow me access all areas and knock off the vat (I wish).

can always say it is for the forum but without cash in hand in a dark alley :p....


Update on the Terraclean process-

Had the service done today and have to say that first impressions are very good.

Driving to the garage was a steady 60 mph returning 42.4 mpg.


Booked in to the Garage and the first thing I saw was this-




Car taken into bay and plumbed in to the machine-




Mechanic bypassed the fuel filter and ran diesel directly to the machine (on petrol cars the machine uses it's own fluid) and then to the injectors (the machine has it's own fuel filter).












Machine powered from the car battery and started up with the revs set at 1500rpm-









45 minutes later the machine stops and they reconnect the fuel lines (that's where the fun started, 20 minutes priming the fuel lines to get the beggar to start again.


Apparently on diesels the system uses a fuel additive and a ammonia type mix to decarbonise the system.


Trip back home at same speed on same road returned 49.9 mpg and around town where I'm usually set at 33.4 mpg I was getting 39.6 mpg.


Suffice to say, there is already a noticeable improvement in fuel consumption and, allowing for the placebo effect, I could feel that the engine was running smoother, quieter and moving through the revs better.

Acceleration seems smoother and even allowing for my Bluefin remap felt more powerful.

I'll do a more thorough run about on various road types and driving styles over the next few days and then I can be sure that there are real gains.

According to the mechanics I had a yarn with, they have all done the TerraClean on their cars and in a couple of cases not told their other half's and even they noticed something was different.


Pity I already had a Bluefin done as they were offering a package of the Terraclean and a Quantum Tuning remap for £250 (bargain methinks).

On the phone at the moment so will look at those pics later but sounds like it was worth while did you manage to wangle the price or what was the final dent in the wallet?

on the pic of your interior, I cant see if that pole they attached to the steering wheel is just maintaining pressure on the throttle?

Paid full price but they did allow me access to the work bay which is usually staff only.
You're right, the bar is purely a pedal lock.

waiting to find my nearest to consider it...

Did you go through the terraclean challenge website and use the garage locator?

I just sent my postcode and they came back and told me I have one in sittingbourne. I cant afford it yet, but certainly bearing it in mind...


I think you have previously used it bit could be mistaken... if you had to 'compare' the terraclean to a good old tin of BG244, whats your pro's and con's for both?

BG is quick to throw in the tank but in real terms it just cleans the fuel lines and the injectors.
Terraclean cleans and lubricates the fuel pump and then strips crap from there on.
I'm currently keeping a record of my mpg doing the same run at the same speeds and driving conditions and will post up on Thursday.
Put it this way I'm happy.

i wouldnt mind treating my motor to this

Already the improvements are increased mpg, smoother acceleration, quieter engine and my fuel range has improved by 40 miles.
I'll post my one week findings and review on Thursday so that the car has had a fair and even test, but if the trend continues I'll be very happy indeed.
I wish I had the disposable income for it I'm tossing between this and tune box
Keep us updated stoney, I'm considering it !
I'll post up the weeks results later tonight.

Right, facts and figures-


Mileage between getting the Terraclean done to last average fuel reading is 228 miles.


11/04/13 - 37.9 mpg (out to garage before Terraclean)

11/04/13 - 41.1 mpg (return from garage after Terraclean)

(Both these trips were same mileage and same roads/speeds.)


The following trips were each a 20 mile round trip dropping the missus to work in stop/start traffic using a combination of 30/40/70 MPH A/B roads and dual carriageway-


12/04/13 - 44.1 mpg

13/04/13 - 46.6 mpg

14/04/13 - 49.6 mpg

15/04/13 - 49.0 mpg

16/04/13 - 53.5 mpg

17/04/13 - 49.0 mpg

18/04/13 - 54.0 mpg


These figures will of course take into consideration that variations in driving speeds and throttle usage during city driving will alter fuel consumption.

As much as possible I attempted to match speed and driving styles but it's not an exact science with average MPG readings, 40 seconds longer at a roundabout or junction will skew the figures a bit.

My fuel range reading has also jumped from 370 miles to 410 miles per tank but cannot conclusively state that this was due to the service or just a nominal increase due to warmer conditions, but usually my range estimate would only go above 404 miles if I was doing a lot of motorway/A road driving and in the height of summer.


In summary, the engine feels very smooth and seems definitely quieter than before and idle level is steadier.

Better torque in low gears and I'm hitting roundabouts in low rev third gear whereas normally I'd drop to second to ensure constant power on exiting the roundabout.

First start up smoke appears reduced and car starts instantly on first turn of the key, glow plug light extinguishes faster too.


In my personal and unbiased opinion, I would recommend the service to anyone looking to improve their fuel economy and keep their engine in top condition.


good review Clive, with any luck it will be the quality of the service and not the warmer temperatures.


Sounds like if you have the income, you should do it! but if you cant afford it yet and just want to do a quick sweep of the cars fuel systems, buy yourself BG244 / 245 (whatever they call it these days) at a quarter of the price, you will probably get a quarter of the cleanup that you would get from terraclean, but it wont be as good for all the system that is cleared out!


Clive, as its coming up to nearly 6 months since you had this service done, how would you say your car performs today (compared to the day before, and after the teraclean service?)


Just wondering if you still really feel the effects of it?


Fuel economy still good, drives like a dream and still very happy with it all.

Still would recommend the service wholeheartedly.


Sorry to drag this back up from the dead but...


I'm getting this done today on my limp moded Ford Focus with DPF!


Reading this has filled me with a bit more confidence. Hopefully this can resolve the blocked DPF issue and allow it to regen for a few more thousand miles!

Let us know how it goes Fella.

Ok, I'm actually gobsmacked!


So much doubt from people over this new way of cleaning but I'm a very very happy bunny.


My DPF was blocked, throwing up the EML and "Engine Malfunction", got Terraclean South to do his magic, clean it, reset the codes and computer. She now runs like a charm, and pulls like a train! Didn't realise how much performance was lost through 86,000 miles of carbon build up!


It ain't half weird watching the car do a forced regen. Starts revving its self up on its own, and the crap that comes out during the whole entire process is amazing.


Now the crunch is to see how she is in a few weeks!


Now some pictures of the process:

All hooked up and ready to go:



First run before soak, that's just a little bit of crap to come out the back:



Cleaning after soaking:



Good result there Fella.

Amazing how much gak comes out eh?

I've read this post with interest.


Just had my Focus Titanium 1.8 TDCI done today, and like everyone else I'm really impressed. I just wanted my car to run a bit better rather than improve the MPG, but going to the garage I was getting 39mpg, and on the way home it was 55mpg, driving the same way.


The whole car seems a bit more refined and much better to drive, money well spent.


The garage I used was top notch, really knew their stuff, and the guy was saying I should consider getting the EGR blanked off now. He uses a service where he downloads the details from the ECU and sends it to a mapping company who then delete the EGR from the map, tricking the engine into thinking it never had one and thus avoiding any EML coming on. Whilst this is taking place he fits the blanking plate.


Like Bluefin, I would also get a copy of the original map should I ever want to revert back.


All sounds good.

Another convert.
There's nothing better than a nice clean engine :d

Oh, one other thing is that if the cardboard cut out of Ed in the reception is his real size, he's a giant of a man! Must be all of 6'9"!

He's 6'7".

Am a takeaway food delivery driver so i do put the miles in, am getting 38.1mpg round town, and not much difference on motorway, car has done 22 thousand miles.


Do you think my car would benefit from this terraclean.

David 295 have you ever tested out leaving your car running for delivery, perhaps getting a second key cut as long as it's parked in sight. If mpg does significantly improve, perhaps you can ask an auto sparky or find an on the shelf system for what they call run lock.

It's what police have, where u can take the key with you leaving the car running, but it will only stay running if you have the handbrake on and the car is in neutral.

Just a thought.

I don't think you will ever get brilliant mpg as a short journey stop start driver, have you tried a good old 'Italian tuneup' and long trip?

I have a 2nd key, but i can't lock my doors whilst engine is running.


My car is booked in today for a terraclean at 3pm

WOW, what a difference terraclean has made I was out doing deliveries last night, and I was getting 56.6, I've never seen my car get that, the most I have ever had is 42.9 on motorway, on a run to Alton Towers.

Another satisfied customer. :)

I'm guttered, I was going to get Terraclean done! I need to get a few pennies in the bank and get it done with the timing belt!

D13 HPD 95

hmm from all these reviews might get mine booked in soon :)

Definitely, as soon as I have the money I will be getting the timing belt changed and terraclean done. I'm getting 51mpg on average in my car and I can only imagine what I would get after a good service and terraclean!

Sent from my MY SAGA C2 using Ford OC mobile app
D13 HPD 95

if i can improve on 32 average ill be happy lol


found a terraclean place not far from me, think i'll book mine in for the start of july, only thing is i wont see my increased mpg as i dont have a trip computer so i'll have rely on the trusty old fuel guage haha.


You could always install a computer ;)


On the plus side though you can just use your mileage, and tank to work it out, but I recon you will get a good result.


i searched on here about fitting a trip computer but couldn't find any proper answers, or it was just for mk1's


If you want to fit one to a MK2, then you just buy a replacement from a higher spec, and you also need to replace the indicator stalk so it includes the reset button, should be a straight swap, then just get an auto locksmith to code your keys to the new cluster and should be good to go!


I would say though, if your going to this effort, do the upgrade and get the MK2.5 cluster, you can get more features from it!


I have a MK1.5 Ford Focus Ghia 1.8 TDCi 2003-53 58,000 miles. So is it worth getting it done

Your car will love you for it.

Well I rang a place up and they will do it for £110 +VAT, I said about my EGR blank, I can remove it and he said yes do that so it can be fully cleaned

Definitely worth it. Also worth buying two egr gaskets from Ford and when you fit the blank plate fit with a new gasket either side

I want to know what the results are like after months not 2 hours on the drive home

Engine runs sweeter and fuel economy improves slightly.
Emissions on the MOT are way down.
