You did a Terraclean servive on my 55 reg Nissan Xtrail on the 29.07.16. As soon as i started my car I noticed the difference my tickover was smooth not erratic like it used to be. Once I started driving the car it was a lot more responsive than before. It was like driving a different car. We have just come back from being on holiday in our double axle caravan. The car had more pulling power than before. Also I noticed when we arrived on site with the caravan was clean. Normally the front would have black rubbery deposits from the exhaust. Although the treatment is not cheap i do think it is worth it.
