Had it done yesterday by a garage in London. £110+VAT. Ouch. Cheaper in the regions apparently.
Asked the guy to take an emissions reading beforehand.
Emissions immediately before

The guy said all the emissions were low to begin with. For example, the MOT hydrocarbons limit for my car is 200ppm whereas my car was producing 11ppm. Carbon monoxide MOT limit is 0.3% whereas my car is producing 0.01% etc. The guy said he wouldn't expect it to make a major difference to emissions.
Whole process takes about 50 minutes but I'd say half of that is them dismantling the fuel system and plugging in the hoses for the Terraclean fuel. Engine was running for probably no more than about 20 mins at idle, with the guy occasionally revving it hard.
Emissions immediately after

On the way home, I noticed quite a lot of white smoke coming out of the exhaust and when the car was idling despite it only being 12c outside. The smoke disappeared after I gave the car a 20mile run and didn't notice any more smoke the next day.
Can't say that I've noticed an major differences in driveability. The engine is very marginally smoother particularly with part throttle responses (think on/off throttle in traffic jam crawls) and initial acceleration is slightly more instant but its only very marginal. The effect is a bit like when you change your spark plugs and air filter - the car feels slightly more eager but I wouldn't say its a massive difference.
Will have to see whether mpg is improved but I'm not expecting a major difference.
I suspect the benefit of this stuff is only really seen in cars that have been gunked up with carbon, have high emissions already, or have been badly maintained. The people who claim to have seen been big changes seem to have crazy high emissions readings in the first place.
I think the theory of this stuff is fine, but based on my experience, I'm not convinced its necessary on a properly maintained car. Although my car is high mileage (120k), turbo'd, has had the Hirsch engine upgrade (195bhp) and been used 50% of the time with supermarket petrol, its always been maintained properly, with a full history / servicing, oil changes every 8-10k (despite using 18k long life oil) etc.
No harm in having a clean(er) engine I suppose but I am somewhat underwhelmed.....
