There have been threads about Redex, Terraclean, branded fuels, what are the opinions as to the best fuel system cleaners? As I haven't had the car long I'd just like to run a cleaner through it. I've used Forte in the past but don't know if it made any difference, never tried Redex, thought about Terraclean but at £108 and reports that the effect only lasts a few months . . . . hmmm
