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 ?

Its a funny thing the whole redex stuff thing.
Some say it's terrible as it does more harm than good, others say it's great. I chucked a couple of bottles through my chimaera when I got it and I can't say I noticed it but if it helps then It's worth the few quid.
Ultimately, if you're concerned about injector quality then pull them out when/if the cars laid up over winter then you know they're performing properly. I'll probably get mine done this winter.

Remove them have them ultra sonicly cleaned flow rate and pattern tested and new filters installed.

I've don't it on a few cars sometimes there fine and it makes no difference some times it's night and day especially when u compare the flow rates.

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
