It comes out of your crankcase.... And our car goes approximately 750 miles between oil changes. If that.

Edit, also i think with a daily driver you get a lot of condensation because the motor gets a lot of start/stops and cooling in between. On the race car everything in the catch can was basically pure oil, because it is run for 7/14/24/25 hours at a time... so very little water actually ends up in it.
