351 Tail pipe puking black

My left tailpipe spews a milky opaque black liquid that runs down the rear bumper and will even leave an occasional black puddle on the garage floor.

Does anyone know what's up with that? I have just shy of 2000 miles. Also, fuel milage is still only 17 with a good amount of highway driving. Can I expect that to improve or is that going to be it?

I'm Luke warm on this car. Still feel it wanders when driving down a straight highway at 70.
