Was kind of dodling along on a country road today when a late model Malibu closed in behind. He must have floored it to pass me. What surprised me was the large amount of very black smoke that spewed out of the exhaust. It continued until he was up to speed and backed off the throttle. It was easily as bad as an old pre-TDI VW.
I guess I just witnessed rich fuel ratio that produced soot and possibly fuel dilution of the oil. Makes me wonder if the recommendation to drive GDIs hard is valid.
