Terraclean anyone?

OMGG - Someone actually said that they thought their exhaust sounded like a V8?

Mine did...but wait...it IS a V8 (the Jag this is!)

Hi everyone, an interesting read. I'm getting approx. 630 miles out of 73 litres of diesel which is 39- 40 mpg so surely earlier on in this discussion the mpgs are wrong or is it my poor maths. Cheers Nick.

Some may have an 80 litre tank?

Your maths is spot on

Some of you might remember I had a terraclean done on my 3.2. We took the intake off before and after cleaning. Standard Terracleaning didn't remove the carbon deposits. However, there is a new product and process coming from terraclean that is 'supposed' to remove all the carbon. My car is booked in for Thursday this week to have the new process done. I'll report back, including before and after photos, once it's all done.

Hi fellow members ,

This is not aimed at anyone .

We all have a choice in what we do .

I too wanted an easy solution to cleaning my intake/EGR system and there isn't one AFAIK .

Today I was scrapping away at the carbon in the top section of the manifold, I got to a point where the majority of it had been removed but there was the last layer left. I carried on scraping and sprayed intake with some WD40, the drier layer of carbon instantly soaked up oil and become this bubblegum like consistency glob.



Now I know what I'm thinking about other elements concerning coking and other's can make their own judgement, in my EGR/Intake clean up thread I will show more media of what I did and what my observations where .

Oooh mud pie...now't like it

Nice one Gup!

Seems they do use a cleaning process but instead opt to use Wynn's (http://www.wynns.be/Product.aspx?p=76695&g=GRP_PRO_FUEL) and Motorvac (> CARBONCLEAN 245 | MotorVac) not Terraclean so the only thing I'll be eating is my lunch

Hey guys haven't read through the whole thread yet so i might have jumped the gun.
Wynns stuff is just a fuel additive in machine it does not have any real similarities with Terraclean. The Motorvac you linked is part of the Terraclean all of which are owned by Uview ultraviolet systems. The Motorvac is quite an old system tried and tested. Terraclean might not have been involved with the testing for Gups post as they are a Canadian company who do have a number of Canadian OE manufacturers/importers but to achieve accreditation in every country is a difficult job. As i said in another post Mercedes in Canada have been working closely with Terraclean to develop the Diesel EGR cleaning tool currently in the early release stages in the uk.

To the people who say there is no scientific evidence of this working i just found this trawling the web


So to understand a little more about the problems of increasing alcohol proportion of fuel in a running combustion engine ………

In North America, E10 Petrol (containing 10% ethanol, another form of alcohol) is quite common (only their Highest octane premium fuels do not contain ethanol while the rest are minimum 10%) and recently the EPA approved Ethanol blend of 15% and is considering 20%. Many in the industry were concerned of course about the ethanol content and engine damage (valves, carbon build-up, etc..). Now the attached study concludes that many engines in the existing car park would be damaged by E15 and the new US law should be reversed or modified to offer consumers a choice.

Ethanol also causes other fuel related problems. Because its lighter than petrol, you can get phase separation in the fuel tank. The Ethanol sits on top. In addition, Ethanol is used as a way to control Octane as well as lower emissions. But it also creates problems in engines that were not originally designed to run on Ethanol blends. Ethanol is both corrosive and abrasive. The Terraclean fuel service certainly helps undo potential problems caused by its use. Use of ethanol fuels tends to increase carbon build-up on Lambda sensors and catalytic converters.

I have attached the above two graphs that show the results before and after a TerraClean service for the switch rate between MAP request and Lambda response these were recorded independently by Frank Massey at ADS in Preston and show the TerraClean service halving the snap acceleration. I’m not aware of a competitor’s product that can independently prove this level of lambda / oxegen sensor cleaning. PLEASE BE AWARE the car tested was a VW AXP engine where the Lambda is inverse i.e. up is lean and down is rich, this is the reverse of usual.



As I understand it UK petrol currently contains 5% Ethanol, but can be up to 10% and that 10% will be the standard in 2013. So the real problems associated with Ethanol in petrol may be just starting in UK. E85 availability is still limited and more prevalent in the Southern USA. Strangely enough, they get a lot of carbon issues in areas like Texas and Florida where Ethanol content is highest and most available!

We stand by the TerraClean product and will happily put its results and long reaching benefits against any alternative treatments.

To those who don't know Frank massey is a nationally acclaimed "Master technician" who runs one of the premier automotive training academy's in the UK. He did do some research showing that injector duration can be decreased using Terraclean - ie the injectors efficiency is restored so the required air fuel ratio can be achieved with smaller injector duration.
I will have a go tomorrow at getting hold of the official data frank recorded from Terraclean uk if anyone doubts the integrity of the above information.
I did find his Autoinform video but there no real technical aspect to that so i'll try and get the official information.
I thought it was quite fitting that the car in the testing is a VW lol.

The Terraclean diesel and petrol systems work in similar ways but use very different technologies i have heard the full technical explanation from Uview's Les Polowsky and it definately works. As per usual misconception is the main cause of rumours.

The Terraclean petrol system was originally developed as a Emissions Free fuel but was deemed to be non-economically viable due to cost of fuel production. When the test engines were stripped down they were found to be spotlessly clean and free of carbon deposits. The re-engineering of the system started from there with it being developed to be a service item rather then an instant cure.
A Terraclean service is not designed to remove all carbon instantly you would need to run on Terraclean fuel at all times to achieve that and you'd be better off smoking £50 notes lol.
The idea being that the service reduces carbons effect on combustion and fuel delivery/post combustion sensors improving mpg restoring performance and in most cases improving emission quite drastically.The system is designed to used as a yearly service to help contain carbon levels while most dealers are advising a Terraclean with your Major service to keep costs down unless you do mega mileage.

If you look closely at all Terraclean images in the UK the diesel machine is a blue Motorvac machine :

Great info ... I posted the VAG info to show that VAG have/used something similar to Terraclean, sorta like to add weight to that perhaps Terraclean does work ...

I have seen the Frank Massey video and lots of his other Autoinform videos. When my idling issue was at its worst I searched on-line where I could book car in with him. Luckily through the help from VWAF plus other info and his videos (which are very good ) I got to the bottom of it.

As you know I've manually cleaned some parts of my intake and replacing some bits of EGR but I believe my air inlet valves must be terribly coked from what I saw in the swirl manifolds just above them, when I do replace swirl manifold/intake/EGR I will photograph the inlet openings on cylinder head and if the EGR specific Terraclean is out by then I maybe up for it ...

I blinking seem to be doing the hokey cokey on this Terraclean thing ...

[MarkTM]

Clearly Gup you need to wait for this new fandangled process that's coming out.

Would be useful if we knew where those 'trial' centres are? We do know there's one in/near Aldershot but haven't heard back from SlackerChris yet
