I bought a Honda Civic LX 1997 model, i see a liquid coming out from my car, after i stop the car, it starts leaking slowly. I use AC when I am driving. Also, when i touch the liquid it is not at all greasy but i see some stains on the road after a couple of hours.

 

If it's just water and pooling other the passenger front then it's likely just condensation from your A/C evaporator.
