  • Terra clean

    Has anyone tried this on any of our vehicles? For those that haven't seen it is a machine that supposedly removes carbon from an engine be it petrol or diesel
    I was thinking about having it done, but not sure if it cleans injectors mine is a diesel van with 60k but did a lot of short runs when it was new,hardly uses any oil, but will it make the engine last longer? The process costs around £100

    Hardly a recommendation but I remember seeing the chaps on Wheeler Dealers do that to a car they couldn't get through the emissions, it worked.

    Got to be worth a go, especially if the miles are up a bit, these diesels are dirty old things.

      Nothing is really going to shift crud in the intake (its horrid stuff). I think Terraclean doesn't clean the injectors. If you want to clean them then ultrasonic cleaning at your local diesel specialist will probably cost less and will be MUCH more effective.

      I wouldn't bother.

        Not that mine burns any oil or smokes, but was wondering if this would refresh the engine ie give the injectors a bit of a clean and free up the rings

          Try liqui moly diesel purge, this has had some good reviews.

            A relative of mine has bought a franchise for terraclean this year for his local area, so I know a bit about this system. First of all I was very sceptical about the system but I have to say having scene some of the results on both petrols and diesels it does work and its worth the outlay.

            It does clean the injectors by leaving a fluid in the tank which cleans the injectors. The carbon build up in the lines is where it really goes to work.

            The only diesel cleaner that comes close to it is forte diesel treatment, I've scene SDI /pd vw engines with worn out pumps / solenoid and injectors blocked be fixed and showing fantastic results for both of the above treatments.

            And just in case anyone was wondering the terraclean company is owned by edd China of wheeler dealers and it cost my relative £8000 for the franchise and equipment for his area. He has had it 6 months and so far done around 40 cleans but to be fair that's just word of mouth and some leads via terraclean website

              That being said I'd still not bother on a car that is well maintained and within sensible mileage. Unless of course there is a problem. But then again it isn't going to be better than getting the injectors rebuilt, or the pump recon'd, or the engine rebuilt.

              It sounds like a halfway house to me. If it removes carbon, especially on a diesel that will quickly return leaving zero gain.

              I'd save the £100 and rely on a good service interval.

                i agree that a good service plan will keep things on top however i must maintain that it does work and you can notice the difference.

                most customers who use the service are the type of people who are working at 100mph and have busy lives who throw there car into the garage every year for its service, pay the bill and come back 12 months later, its very easy to offer the service as a add on which most buy into.

                to be honest i enjoy servicing my maestro

                  Hiya, yes it will make a big difference, when the terra clean diesel is being done, it first has a really potent cleaner put into the intake to clean all the ports out and then the fuel lines are disconnected from the lift pump and the injection pump is plumed up to the machine. This then makes the car run
                  At different revs on a solution of cleaner/fuel
                  For around 45 mins and this cleans about 99% of all the crud out of the pump,'injection pump and pistons and ports etc. plus the exhaust gets a good blast out to. I have seen this work in person and make a massive difference to fuel economy and performance let alone emissions. And yes clearing old carbon and crud out will make the engine last longer... In my opinion... The old prima deserves it!

                    If you have ever tried to remove the crud from the intake manifold and inlet ports you'll know that no chemical cleaner squirted into the intake is going to make any real difference to how much is there. It is horrid stuff which is very difficult to remove. If by any miracle it did work (which it doesn't) where does all this loosened crud end up? Yes being sucked through the engine and turbo (if fitted) not a good idea.

                    Have you seen how much crud is in a fuel injection pump? Probably not as it is incredibly clean in there. If it wasn't then the pump would be scrap in minutes as the tolerances needed for the pump to work properly are extremely tight.

                    It may be far more effective on petrol engines but on diesels it really isn't doing much.
