So far the engine felt smoother & lesser vibration, and lesser throttle input required to get my autobox to downshift. Initially after I left the place I can't really feel much difference but I guess after driving through my usually office route definitely there's some positive change in overall driving experience. Well per session is not enough for my car due to high mileage, I need at least another seasion to really benefit from the carbon cleaning but I think Im happy with current result. I do not want to be removing so much carbon though as it might introduce other problems later. Dave mentioned it's good to do it every 20-30k interval besides normal servicing as it helps to clear/reduce down carbon build up in the combustion chamber.</blockquote>
