    Any ideas what is the best stuff to use. I'm going up the garage in a minute and need some advice if i can use this stuff at all? or if there is a different type i need for a Turbo engine.

    With modern fuels, you shouldn't need to use injector cleaners.

    if you mean the stuff you put in the tank then forget it.

    after 50k miles, the injectors will have a poor flow pattern and should be removed and run through a proper ultrasonic injector cleaner - this will restore the flow pattern and increase max fuel flow, but tends to make the injectors noisy - that was my experience. the car did run a lot smoother though.

    although if you run on modern fuel such as optimax, there is a chance they wont need doing - my last car (volvo t5)had done 55k on cheap fuel before i got it.
