Ok. I found out exactly what it is. It is coolant that is leaking.

I woke up this morning going "oh shit". We thought it was oil because the stain that was on a tissue that I used to wipe up the stain was oil. BUT, I remembered that that piece of tissue was in fact oil because I used it to check the oil levels that day. BIG :doh: on my part.

So I just put some saran wrap under my car to catch the drips, and it was green.
