"I don't often leave reviews but this…"

I don't often leave reviews but this one I believe deserves one. I am a technician of 23 years and I admit I was a bit sceptical of the product. Until I tried it on my own car. My car has regular oil changes so I didn't expect to see anything unusual. After the final cycle had finished I checked the filter to find all sorts of bits of metal attached to it. Who knows where they came from, but they have been inside my engine for I don't don't know how long. All the dirt and filth that was removed has blown my mind. The engine was quieter and seems to have more performance which is a bonus. I strongly recommend this service. I will be convincing all my friends and family to get it done.

"Just had my car done and cannot believe…"

"EDT at cornerstone autos ltd"

I have a 64 reg for galaxy 2.0 tdci that has covered 148,000 miles. Before EDT treatment my car was unresponsive and sluggish.
I took my car to CORNERSTONE AUTOS LIMITED in ilton. What can I say except they were very friendly and the service was exceptional. Now after the EDT treatment my galaxy drives like a totally diffrent car. It feels like someone has fitted a supercharger as the car drives brilliant and there is so much more power and it's not sluggish at all anymore. Thank you Cornerstones....
I will be recommending you to everyone I know

"Engine flushed and clean."

On my car i get 38mpg max thats after a remap. Today morning i had my car done with this oil clean treatment at renovo autocentre manchester thought if i was lucky i would get around 42-43mpg and to be honest i was really suprised i got alot more i am averaging minimum 50.4mpg now plus my engine sounds so much quiter and its smoother when idle and whilst driving. They told me you will feel the difference straight away and i did. Overall would definitely recommended having it done and will have it done again in the future. Just want to say thanks guys brilliant job.

"I had my car serviced at Cornerstone…"

I had my car serviced at Cornerstone Autos,Ilton and was offered an EDT treatment on my car. The staff at the garage were great! They explained everything and were really helpful.
My car is performing so much better and I've noticed that I'm saving fuel as well! Great team all round and I would definitely recommend both the garage and the EDT treatment. Cheers guys!!

"Variable valve issue fixed after 1 treatment"

I own a 2001 Honda Accord 1.8 vtec and for years I've had a hesitation/flat spot at around 3000 rpm. I new it was a variable valve issue and I spent money on numerous cans of oil flush and new oil but flat spot was still there. EDT offered to do a treatment on my car and ill be honest, I didn't think it would fix the flat spot. 1 treatment later and not only has the flat spot gone but the car drives like it's got a second wind. Also the amount of sludge it pulled out when doing the treatment was unreal. Worth every penny and ill be doing it on every oil change.
