This is a repeat of my post in the specialist tuning section - this time targeted at R36 owners:
Someone recently advised me to use injector cleaner mixed in the petrol tank every few weeks or months. Does anyone have advice whether this is a good idea for a petrol V6? Is it recommended by VW?
If yes, how often? And is any brand OK or just genuine VW/Audi product? There's a small metal can from Audi for around $40 which is said to be no different to the Holden plastic bottle for around $8. Then there's all the aftermarket ones such as Nulon, Wynn's etc. Thanks.
