HI my fd oil has just been changed about 6.5K since last change. 2009 model with a proper drain plug, i noticed this is magnetic and appeard to have some form of graphite grease on it. The oil had no 'bits' in it but appeared to be stained with the grease. Anyone on here experienced similar? There is no play in anything or nasty grinding and the bikes done 14,600 miles.
