Redish not grayish
My car has always left a light gray exhaust residue on the underside of the car from the collectors back. I now have a redish brown residue. New batch of Cam 2 110 from a track these 15 runs. Is this from the purple dye in the fuel?

That is a sign the fuel contains to much MMT additive in it.Methylcyclopntadienyl manganese tricarbonyl is used to boost the octane rating of the fuels.
