Knocking during idle
I always use premuim fuel (Mobil 93) and recently added fuel system cleaner until I do the Fuel Induction service, for a while my engine knocks during idle & I don't know where it's coming from? Is it possible that I need a tune-up? I'm hoping this is minor becuz it's really irritating me to hear my beautiful VQ sound like that... any suggestions

To me, it sounds like the sound it not Fuel related...Fuel related would be more of a tap or a clicking sound...your problem sounds engine realted to me:::
Try to locate the sound when its at operating tempurature (get underneath, over the top)...Is it a deep knock or a light knock ?? You may just need a heaveir weight Oil or even a different Oil Filter...if your using 5W-30 try using 10W-30 and the knock may go away since its gettin warm lately
Try Synthetic too while your at it >>> MOBIL1 10W-30 Fully Synthetic Motor Oil

Re: Knocking during idle
why did you add that to your car, was it running poorly??? unless it does you shouldn't use any of that stuff... and no, there's probably nothing wrong with your car, just turn the volume on the radio little higher
