Get a bottle of this stuff, and put the whole lot in mixed with a full tank of 97 or even better still 99 octane petrol (Shell V Power), and give the insides a bit of a clean up. It's the only stuff i use, normally once a year, and actually notice a difference afterwards.

ps: you can get it from Halfords for an extra £4 if you want it quicker.
