I'm just running through my first full tank of gas on my new 50th Anniversary Targa LX. Just the other day as it was sitting on the concrete.... i noticed a oil spot below the end of the exhaust. Sure enough...quite a bit of oil is collecting on the end and then dripping out. Is this normal?...good/bad? Maybe it's because I'm running on the reserve fuel right now? Is the oil injection system just injecting to much fuel? Any help will be appreciated.
