Pickup for my Honda city improved I instantly after process was completed. Engine running was exceptionally smooth and sturdy. Would recommend to anyone who is looking for the betterment of the cars performance.

I recommend green engine solution guys because after engine carbon cleaning for my innova the performance increases slightly and It have a nice chnage in milage of 2k pl (before cleaning I have average milage of about 14kmpl). And it has smooth engine sound even in 140 after cleaning. They have done excellant job. Go visit them guys.

Madhu M

I had a long drive till Thanjavur. I'm 100% sure, decarbonising made difference in vehicle performance and fuel efficiency.

Usually it makes 18-19kmpl for long drive speed between 80-100kmph.

Yesterday it made solid 21kmpl for the 300kms drive speed between 80-100kmph.

And also performance wise, pick-up of the vehicle had got noticeably increased that I could feel everytime when I slow down for speed-breaker and while throttling again. There is no lag and can experience the pull, enginemakes.

I'm sure in adding decarbonising as on of the to do list in every service interval

I had done my Fabia diesel engine decarbonization in Ashwin hydro. Feeling the engine noise and vibration are good and smooth now. Also driving and engine pickup is good.

I am owning a Skoda superb 2014 model. 75000kms driven. Recently I had some uncomfortable performance and heavy black smoke while driving. After I don the decarbonizing from Ashwin Hydro Carbon Services. Now I could feel very smooth in engine performance, pickup also works good than before. It was really a good experience. Regarding increase of mileage, will let you know shortly. I recommend everyone to go for it to make your old car to a new one. Thank you very much for the service. Highly recommend for 5/5 ratings to their team.
