Injector cleaner

[Speed 3]

I have previously used Redex type fuel injector cleaner in the fuel on higher mileage cars. I remember a Top Gear piece on the cheapest ways to recover lost BHP on older engines where it came out tops with a noticeable % gain. Would there be anything peculiar about the S6 which would mean this unadvisable ?

Personally iv always preffered a tank of super unleaded to run through, it has all the cleaning agents etc that is unless you run it on super already, in which case i dont believe you would receive any benefit.. no science to back it up but it seems to work for me, even if i do run my Tuscan on it lol my daily V6 Alfa however, gets one a month

Good point, I do run it on V-Max.
