I am not saying that additives are not to be used, just not the cheap ones, they do very little. One additive I use consistently is BG44k, it is not cheap (here in the UK) but really does work in cleaning the fuel system. Outside of this garages offer an fuel system clean, with specialist equipment for about $100 ??????. I have had feedback to say that people have had excellent results....... like most things everyone has an opinion !!!!! I have used this for the last number of years on all my cars.......it made a big difference when I did it on my 6 series for the first time!!!
