Only thing the guy said to me wasI must admit it sounds very attractive and it can find some of my lost ponies it may be worth it ! May ask a few questions, removing the deposits from a 15 year plus engine will have benefits but will there be any downside to it ?
May give them a call and see what they say...
Don't do a Ford Diesel as the carbon deposits are the only thing holding the injectors together! Ha.
He said to me after mine was done that he had never had any issues on any car except a ford diesel.
Obviously he will say it's good as that's what he does but it was after he had taken my money.
