Sounds interesting Edd...what system did you use (was it a head off job?)

No need to take the head off, thats the good thing about this process. They connect a machine that contains two cans of a high tech fuel, bypassing the fuel pump and the engine runs off this for about 30 minutes. The tech goes under the name of [link=http://www.youtube.com/watch?v=p5SFUAp8iPM]Terraclean[/link], they have some pretty crappy american marketing techniques but the technology seems to hold up. Well worth the £100 if you ask me. Edd

Just had my engine decarbonised and I have to say I was a bit skeptical at first but the results are pretty good. I'm not sure exactly how the tech works but its certainly made a difference to how the engine feels. Its got a fair bit more poke, right across the rev range, but most noticeably lower down. Apparently the system they used cleans both fuel injectors, combustion chamber and then post combustion areas too.
It would appear any high mileage/older car could benefit (with injection systems), its obvious to me now that carbon build up can alter how well an engine runs. Its another step in the right direction in regards to restoring lost ponies over the years if nothing else.

Indeed, if you can get past the corny marketing the product itself appears to be a worthwhile engine refresher/treatment. In regards to throttle response and engine eagerness and I would compare the result not too dissimilar to having the Promax chip fitted. Edd

This cant be compared to a can of redex or STP, its not a chemical process, but one that uses physics apparently. As I understand it the highly refined fuel in this process is negatively charged by the machine, this means it attracts to the positively charged carbon deposits in the engine, which are then vaporised and shot out the exhaust. There are two solutions used, one to clean the injectors and one for the post combustion area like the cat converter (my car doesnt have one). I'm not sure how much is being removed but one treatment seems enough and it certainly can be felt so its obviously doing something. I think it may also have a cleaning effect on the oxygen sensors with can also improve engine response. Edd

Miles Ahead Motor Servicing in on the A406 North London, a small outfit but the mechanic successfully connected up the '44 to his machine (modern cars are much easier apparently) and all was done in about one hour. Although next time (its a once a year treatment apparently) I will probably use [link=http://www.monster-sport-europe.com/index.html]MSE[/link] as they are close to Promax in MK. Edd

I think most people think its snake oil, however after having it done I can report a definite change for the better as described above. I'm pretty sure the next person to try it would have similar results. Edd

Yes it will be interesting, I'm eager to see how MPG has changed too, I usually average 25-26mpg on spirited runs to Cornwall, so we will see when I go next month. Edd

If it really was something wonderful, there would be a better explanation of it. Their website is devoid of facts. The pseudo science explanation is complete nonsense - negatively charged particles attracting positively charged carbon? And what's a "physics" process?. This is as bad as all the cosmetics adverts. No carbon in the product? then what is the engine running on? never heard of arophatic? compounds. Aliphatic compounds are the hydrocarbons that are in chains, (like petrol [
] ) not in rings (aromatics) I can understand how some processes might dissolve the carbon based grime inside an engine (or in an exhaust) - however modern fuels and oils do this job don't they? Looks to me like any other "fuel treatment" you can buy. I just watched [link=http://www.youtube.com/watch?v=5VCuki_-vXQ]This video[/link] - from the US - the man from the company is again talking complete scientific nonsense. "Columbic fractionation" for example. In this video they seem to suggest that they are actually using a hydrocarbon fuel, but with some nonsense about negative charges. How about this ".....the utilisation of technology rather than chemistry. This process involves refining standard petrol and removing the part of the fuel that produces carbon when burnt. It also reduces the particle size of the fuel flowing from a patented Nano-technology process within the machines’ reactor and finally passes a negative charge through the fuel...." [8|] [link]http://randstadonline.co.uk/TerraClean/pdfs/terravision.pdf[/link] As for cleaning direct injection engines - the problem in those seems to be in the inlet manifold / back of the valves, because there's no fuel to cool / clean, (and this process wouldn't help. ...Anyway I'm off to squirt some anti-ageing cream into my inlet manifold []

I think he means it leaves no carbon deposits. I did warn re their marketing techniques[], I cant comment on the crappy science, all I can report is the difference I can feel, which is certainly real and tangible. Lots of people are sceptical and perhaps rightly so, but of those that have used it I don't know of any that have stated it doesn't work and therefore it really is snake oil, its usually the opposite.

Update, ok I've done about 300 miles since having this done, mostly spirited A and B roads, not had a chance to check mpg yet but the performance remains the same. Engine revs more easily and feels a tad more torquey, throttle response is improved. Its subtle as its only restoring the engine to how it should be but its certainly noticeable and a welcome result. I'm running the same V power fuel as before and no weight advantage. I know the car well enough to perceive a difference when I have a passenger or full tank of fuel and this decarbonising has made an improvement that can also be felt. I can also detect a small change in exhaust note. The process has obviously done something, whether cleaning or replacing the oxygen sensor would have a similar effect or whether it is actually decarbonising the engine is hard to tell. Its certainly appears to have had a replenishing effect. I think aporschefan in now considering having this done so we may be able to get a secondary opinion on the process soon. Edd

The website's pseudo scientific drivel certainly doesn't inspire confidence in their product, however, I am also comfortable with the fact that Edd is really seeing a "gain" regardless of how it was achieved. I doubt I'll be treading this path. I can clearly remember "Formula Shell" petrol from the 1980's and its amazing Vauxhall engine destroying properties. That has made very wary of all "clean your engine out" products, particularly their medium to long term effects on an engine. Edd, if your beasty is still running OK in 50,000 miles time I'll think about it. Keep me posted!

I agree re terraclean marketing, appears to me that they may have shot themselves in the foot with the JML style adverts and Edd China's face everywhere, being a Canadian company perhaps the US style advertising is customary. It you can look past this the product itself appears to hold up to expectations. Re damage to engines, I did a fair amount of reading before deciding to try it and so far I've not heard of any damage caused, this product has been running in Canada and the US for 15 years or so. It would also appear several Subaru and BMW dealerships over there also offer it as part of their service schedule. Edd
