Any offers on this please ? we have a 156 T/S 2.0 well looked after, never uses oil & 7 months months since a service , oil is still golden & clear, so great! But on the JTS 2.0 the oil was rather black well before its service & has looked very black since just a few days after its recent oil change. Other JTS 2.0s oil goes BLACK? I am concerned about this, ALFA don't seem to think its anything. Is Selena Racing Oil black & straight out of the ground?
