I came back from church this morning and saw this suspicious puddle as I was pulling into my garage. It is directly under the exhaust pipe, and also about a 1.5 feet back from the pipe. I consistently park my car in the same location every time.
I haven't seen this puddle ever before. It is not from melted ice or snow from the car. We haven't had any snow for the past 2 weeks. The puddle is black, so if it is water, it is dirty water. I think it is just water, probably condensation from the exhaust when I preconditioned the car this morning before leaving for church. It was about 5 degrees F. this morning. I didn't notice the puddle as I got into the car to leave, however, I did smell a slight burnt rubber smell when I got into the car. I assumed it was the normal burnt smell which is caused by a new engine burning off some of the coatings from the manufacturing process. Now I'm not so sure.
Common to direct injected (DI) engine is sooty (black soot) deposit covering the exhaust - which contaminates the condensation that builds up within the exhaust pipes, hence the blackish water that trickles out.
