My car never felt better

Had an EDT treatment on my 2007 VW Jetta TDI sport. Staff were very friendly and helpful and the car is running better than ever. My mpg has improved drastically and I have full power back after the engine was sludged up by a faulty egr and dpf. Would definitely recommend to anyone

very impressed

my Peugeut 405 mi16 with 258k miles had terrible issues with maneuvering at low revs, it would constantly stall and require over revving to keep it moving. This was in reverse or forward. My old school and very trustworthy independent garage recommended a full service and EDT. The car after this process was very noticeably quieter and the stalling was no longer an issue, it took me quite a while to stop the muscle memory from overrevving when pulling away! I had my daughters 10 year old mini hatchback done too and it was noticeably smoother to drive.

Amazing product

Amazing product, it is like driving a car with a new engine, considering my car has done 85000 miles. Does not take long and to see the muck that comes out of your engine is unbelievable. Definitely will use this method after every third oil change. Highly recommend this

First time I have used this system and I am totally blown away with the results. Engine is as clean as it was when it was new, a lot quieter and the power is back to the way it should be. Fantastic service from EDT.

EDT #CleanEngine Win

So, this is my 3rd time having EDT on my car (different car - Seat Leon Cupra 300 2018 - 30k miles) so I thought this is the perfect time to have it done! It's an excellent treatment that cleans your engine while having fresh clear oil, so engine will be back to brand new again. It's worth the service hence the 3rd positive review using the EDT

EDT engine clean at AW Auto services

I had my 2006 Chrysler voyager engine cleaned today, before having it done my vehicle was a bit sluggish at lower speeds it now runs a lot smoother and has a more get up and go. Was pleasantly surprised by the difference it has made.

Removed loads of carbon and muck from my 2007 Mitsubishi 1.5 diesel. It now sounds a lot quieter on idle and runs noticeably smoother. I haven't checked economy yet but lower friction in the engine must improve economy. I feel sure that this will increase the life span of my engine and turbo. I can recommend this to anyone, its the best £120 you can spend on your car. Thanks Four crosses Garage for advising this treatment

Thanks, New Inn Motors

Mike at New Inn Motors, Cardiff did the engine flush on my Citroen 1.6 C4 at the last service. It has approx 65k miles on the clock. It's always started well and is in good nick so I wasn't sure if I'd actually see much difference.

My motoring is dominated by a weekly 400 mile round trip from Cardiff to Cambridge on motorways, and I generally averaged 43.2 MPG all in. The last two journeys since the flush have been just over 46 and just under 49 (the 2nd was slower due to traffic, so I expect better MPG). So that's 6.5-13.5% improvement in fuel economy, you could say (though it's a small number of samples, so not yet a true scientfic survey!).

This will pay for itself on fuel economy alone in just a few months.
Plus of course after a few k miles the oil is still completely clear.
Just one more reason why New Inn Motors is my garage of choice.

Fantastic service from day one

Fantastic service from day one, from meeting David and Adam to them introducing us to to their detox treatment machine. David answered a lot of questions I had, providing useful and informative info.
My team have now recived our EDT detox machine, along with full training and live demos.
Two days in and 5 detox treatments completed with great results and happy customers.

EDT customer review (not garage)

As per any normal person I checked the reviews before I got it done on my car, after closer inspection the reviews seems to mainly come from garages that offer the service along with all the videos online. My oil went back to black the day after the edt detox, the engine feels as smooth as it does after any oil change with decent grade oil, power is identical and I’ve just finished a tank of fuel and guess what.... same mileage as normal! Don’t get me wrong, I can see a benefit to cleaning your engine out but I cannot see how it got to the claims made and also am now very suspect to all the reviews as they all read very similarly and suspect a garage HAS to write a review

IThe reviews are similar because thats what happens to the vehicles !! Many of them are direct customers which EDT never see !! We also have many Partners for several years that have done thousands of cars each !! We have been Trading 6 years and done over 120,000 cars and won Independent Awards . Along with multiple automotive journals Reviews

Recently had an EDT treatment on my Audi A3 which hasn't had an oil change in 3-4 years. I haven't noticed any difference in engine performance or fuel economy. If anything its gone down slightly. I'm not sure i would be happy selling or paying for this treatment, I've had no benefits from it.
