I know its not an issue, but I'm curious as I look at countless cars with normal deposits on the plugs, then up pops one with pinkish/red coated plugs, so...
Anyone who has had pink spark plugs please post what fuel brand fuel they were using and what additives (if any). Obviously bear in mind they could be stained from using a previous brand of fuel or additives, so if the car was bought second hand and still has the same plugs or you have switched brands, please state so.
And if anyone knows what chemicle causes the pinkness, feel free to educate me; As one of side studies is finding out which brand fuels contain what chemicles in their additives to boost/maintain octane/combustion cleanliness.
